This session discusses techniques and tools for debugging enterprise applications (without using System.out.println()!)

It's an interesting dilemma – we have the best tools for software development ever, yet developers are still debugging enterprise applications using ystem.out.println()! This session discusses techniques and tools for debugging enterprise applications. It shows how to perform remote debugging through all the major IDEs, either on the same machine or across a network. It also shows how to debug using the command-line jdb debugger (the only one guaranteed to always be available).This session shows how to debug web, EJB, and lightweight enterprise applications. It discusses class loaders, interactive enterprise debugging with Groovy, and how to automate repetitive tasks using JWebUnit and Selen

Regular expressions should be an integral part of every developer?s toolbox, but most don?t realize what an important topic it is. Regular expressions have existed for decades, but many developers don't understand how to take full advantage of this powerful mechanism, either through command line tools and editors or in their development.

This session shows how to fully exploit regular expressions. It begins with the basic premise of how regular expressions work, then shows how to take advantage of the RegEx library built into the Java platform. This session shows how to use wildcards, escape characters, meta-tags, character class operators, look-aheads/look-behinds, and how to use the greedy operators effectively. It covers regular expressions from the beginning through to advanced usage, both in Java and in tools that support regular expressions. This session is packed with real examples of regular expressions (including a game show with no fabulous prizes).

Key Session Points:

This session shows how to use Java as the building block for domain-specific languages. It discusses the next revolution in programming: language-oriented programming and the nascent tools that support it.

If you look at the way advanced programmers in highly dynamic languages (like Lisp, Smalltalk, Ruby, etc.) work, they tend to build domain specific languages on top of their low-level language. The language syntax itself becomes building blocks for languages that are highly specific to their problem domain. It’s not as easy to apply this technique to a static language (like Java), but it is possible. This session shows how to use Java as the building block for domain-specific languages. It discusses internal and external DSLs, with pros and cons for each. This session progresses from creating an internal DSL using Java syntactic elements as keywords through using compiler-building tools to c

Security's become a hot topic among enterprise developers in recent years, but to many developers, security is still the white elephant in the middle of the room. Discussions about security usually begin with, "Uh, we'll worry about that later", or, "Start with two really large prime numbers.....". Security isn't as hard as developers make it out to be, but it is something that developers need to face and recognize.

In this talk, we'll extract the 10 Items on Security from Effective Enterprise Java and talk about them, giving developers the basic heads-up they need to have when building enterprise systems in Java.

There's a set of fallacies that every enterprise developer has fallen for at some point in their enterprise development lives, and unless they've come to realize it early enough, all cause big trouble and painful learning experiences in the long run.

In this talk, we'll go over the Enterprise Fallacies, discuss why they're so insidious and easy to fall into, and how developers can go about making sure they avoid them in the future. Discussions will be relative to both .NET and Java, as well as the emerging Web services stack, as the Fallacies know no technical boundaries.

Rules engines are powerful beasts which allow you to program in a way in which you specific rules and facts, rather than a linear set of instructions.

Learn about how you can use Rules Engines in Java development to take care of complicated problems.

Rules engines are powerful beasts which allow you to program in a way in which you specific rules and facts, rather than a linear set of instructions.

It takes awhile to get used to "Thinking in Rules", but it gives you immense power for particular logical problems. You pass control HOW the rules are applied to the rules engine, and just give it the information it needs to get the job done.

Rules based systems are often great solutions for enterprise problems, and are uniquely useful for building so-called ""business rules"". Now you have an external view of your business, and can change behaviour via the rules rather than hard coding your application.

What? Another programming language? Are you kidding me? That is what we often feel when something new comes around, and is something you may be feeling about Groovy. However, Groovy could fit a niche for you in your daily toil. It is the swiss army nice that Perl/Ruby are, yet lets you work in a more structured way, and plays nice with the millions of lines of code already written on top of the Java Virtual Machine.

What do we really mean by "performance" and "scalability"? This talk gets into the meat of problems which cause our applications to degrade. We will focus on issues such as problems caused by the database being a bottleneck for our application, and see how we can architect our solutions to bypass the issues, resulting in a solid system which scales with the increased load.

Not only will we look at the factors, but I will delve into a couple of case studies to show how real world problems were solved!

Frameworks? We don't need no stinkin' web frameworks. OK, so maybe that's overstating the case. Web frameworks do plenty of good things, but sometimes they can also be golden handcuffs. Too many web developers fall into the trap of thinking, "If it can't be done by my web framework, then it simply can't be done."

This presentation focuses on the cool things that you can accomplish by stepping out of your web framework and getting closer to the underlying technology. We'll take a detailed look at what really goes on during the request/response cycle, and how new techniques like AJAX allow you to break the mold. We'll look at the clever things you can do with MIME types, User-Agents, and HTTP Headers in general.

Old technologies like CSS, DOM, and JavaScript are experiencing a renaissance under the guise of new names like DHTML and AJAX. Google Maps and GMail are literally redefining our expectations of how rich a web application can be by using these technologies to their fullest potential. Co

Hopefully your test plan involves more than, "Well, it compiled..." JUnit is fast becoming a required part of the modern Java developer's toolkit. Unit testing your Java classes is a great start, but your test plan shouldn't stop there.

This talk will introduce several additional testing tools for the web developer -- HttpUnit, Canoo WebTest, and JMeter. These tools allow you to test a live website with no changes to the production code. Even better, you can test sites that have been implemented in technologies other than Java.

You will see code examples and live demos of these tools in action. We'll talk about the differences between unit testing, functional testing, and performance/load testing. Come get "test infected" -- you'll never look at the development process the same way.

By Scott Davis

JUnit is more than a Java testing tool -- it is a testing framework that can be extended to test non-Java resources as well. In the first presentation in this series, we examined three JUnit extensions that allow you to functionally test your website. In this talk, we'll look at three more tools that web developers should have in their toolkit: JsUnit, DbUnit, and the W3C Markup Validation Service.

JsUnit allows you to test your JavaScript. Anyone who has done JavaScript development knows that cross-browser support of JavaScript is a tricky proposition. Rather than emulating a specific browser, JsUnit can literally launch different browsers and execute the test suite to ensure that the JavaScript code you wrote actually works.

DbUnit allows you to stage your database tables for unit testing purposes. You can insert and delete information as a part of your test suite. While the database isn't technically a part of the web tier, we'll show how the proper use of this tool allows you to test the other parts of the web tier with ease.

Too often, Swing applications are slow, ugly, and hard-to-maintain. It turns out that it doesn't have to be this way. Swing can be used to create highly-responsive, beautiful applications that are very maintainable. If this isn't consistent with your own experience, don't feel bad; its not very obvious how to make Swing sing.

In this session, I explore three topics that lead to much better Swing applications:

Proper Swing threading

High-quality third-party Swing look-and-feels

Good practices for coding Swing applications

In the threading portion of the session, I explain Swing's event handling architecture and its implications for Swing applications. Understanding this topic is crucial to creating highly-responsive Swing apps. I demonstrate how to use this knowledge in the form of many live-coded examples, and I show how frameworks like SwingWorker and FoxTrot can make this easier. Java's default look-and-feel, Metal, is awful (and in my opinion, the "Ocean" theme in JDK 5.0 doesn't do enough to improve it

Are you spending more time plumbing your Swing applications than solving business problems? Has your Swing application grown out of control? This session is for you.

In the first part of the presentation, I analyze the architectural problems that plague many Swing applications and present architectures that overcome these problems. These architectures are presented in terms of principles along with a reference implementation. You can therefore either adapt the principles to meet the needs of your existing applications, or incorporate the specific ideas of the reference implementation into your new projects. Fortunately, there are some existing frameworks that have done some of the architectural work already. I present some of these frameworks in the rest of the presentation.

For many of us, XML has become a ubiquitous presence in application development, whether parsing, validating, or manipulating it. For many of us, all that XML is coupled with pain, in the form of tedious APIs (like, say, the W3C DOM API) and confusing technologies (oh, I don't know, W3C XML Schema?).

In this session, I share the following tips for making the XML in our lives a little easier to deal with:

- Use StAX instead of SAX

- Use StAX to create XML

- Use JDOM instead of W3C DOM

- Use XPath to select XML

- Use Jaxen to enable XPath over custom trees

- Use RELAX NG instead of DTD or WXS

- Use Trang when DTD/WXS output is required

- Use Sun's RELAX NG Converter when WXS input is required

- Consider RELAX NG's compact syntax

- Use Schematron to extend schema languages

- Consider XML namespaces for versioning

- Ignore unknown namespaces

The Eclipse project's SWT GUI toolkit provides one of the only viable alternatives to Swing for creating so-called rich client applications in Java. Whereas Swing paints its own widgets and has distinguished itself with a complex (and often obtuse) API, SWT relies on the host operating system for widget rendering and sports a simple, clean API. If your goal is to create a Java application that "looks" like a normal Windows application (or OS X, or Linux), SWT will revolutionize your world. In this session, I introduce SWT from the ground up. I start at a high-level, but quickly move into the details of SWT's API. By the presentation's end, attendees will have a solid understanding of SWT.

This session picks up where SWT Fundamentals leaves off. Among the advanced topics I discuss are creating custom SWT widgets and exploring tight native integration. I combine another compelling topic with the advanced SWT material: JFace. SWT is a more akin to AWT than Swing; its concerned more with wrapping native functionality than providing any high-level abstractions. JFace is an API on top of SWT that provides such abstractions. The combination of SWT and JFace is comparable to Swing. My coverage of JFace includes an introduction to several of its frameworks, such as the Viewer and Window frameworks, along with many examples. Learning JFace will enable you to write complex SWT applications much faster.

You can do some pretty cool things with XML these days (despite what some curmudgeons in the technology world may claim). In the past few years, XML has solidified its place as the lingua franca of data sharing and data manipulation. But XML as a data transfer language is only marginally interesting. Things get really exciting when XML is dynamically transformed into other formats. In this session, I focus on two XML formats which can be readily transformed into high-quality presentation-centric output formats. XSL-FO is a typesetting format for XML that can be readily converted into PDF (or Postscript and some other formats). SVG is a vector graphics language in XML -- a sort of open-source version of the popular Macromedia Flash format. SVG files can be converted into beautiful, completely scalable -- and interactive - - images.

As recent high-profile web apps such as Google's GMail have shown, modern browsers are capable of natively rendering web apps with highly dynamic and compelling UIs - fetching server data without page refreshes, animating and manipulating page contents on-the-fly, even offline use. The line between web and "desktop" apps is blurring.

Experienced web developer Dion Almaer (editor of TheServerSide.com) and noted Java desktop expert Ben Galbraith will describe and demonstrate these new techniques, including how to adapt modern web frameworks such as JSF and Tapestry to ease both the creation and maintenance of these types of applications.

O/RM (Object/Relational Mapping) seeks to eliminate repetitive or tedious work enabling the CRUD (create, read, update, delete) that underlies most applications. Hibernate is a popular, open-source O/RM tool that uses reflection (instead of code generation, like EJB, or bytecode injection, like JDO) to manage your persistence layer. This session will introduce you to Hibernate. After an overview of common usage scenarios, including web and enterprise applications, we'll examine the basics of getting Hibernate running. We'll cover the mapping file format and syntax, including common relational mapping structures. Then, we'll examine the Hibernate API for interacting with the framework. Finally, we'll cover the common architectural decisions you'll have to make as you include this (or any other) O/RM framework.

Hibernate is easy to get started with, but can sometimes be hard to make efficient or secure. In fact, the default settings for Hibernate createapplications that will run slowly, cause unwanted round trips to the database, and may be more restrictive and/or permissive from a security standpointthan you would otherwise want.

This session will show advanced techniques for tuning performance, including:

• advanced collection mapping strategies

• lazy loading

• cascading update management

• lifecycle management

• Hibernate's interceptor layer

In addition, we'll examine the security considerations when using Hibernate. Often, single-credential data access isn't enough for sensitive data. We'll

walk through using per-user credentials for data access, logging security information about and through Hibernate, and accessing data sources through secure application servers.

By Justin Gehtland

Web Services are message-oriented. This means that any application intention (the need for security, for transactionality, for reliability, etc.) must be included in the message and not just assumed as external context. The WS-Security specifications are very advanced and currently being used in the wild to create robust, secure web services.

This session will examine these specifications, including:

• WS-Security

• WS-Policy - for sharing enforcement and encryption strategies

• WS-Privacy - for agreeing on privacy policy for service usage

• WS-Encryption - for encrypting or signing all or part of a message

• WS-Trust - for creating a single-sign-on solution

• WS-Federation - works with WS-Trust

These specifications, plus others like WS-Addressing and WS-Notification, provide a platform for communicating security intent across multiple network

layers and many platforms. Of course, these specifications only define modifications to the messagapplication author. We will demonstate these capabilities using the Axis toolkit a

For centuries people have used crypto to build (and break) secure systems. Computers have only raised the pitch of conflict, providing enormous cryptographic power at commodity prices. Most programmers do not write their own crypto libraries, instead relying on the services of an operating system or virtual machine. But even with all this support, building secure systems is a daunting task.

This talk will cover three things all programmers

need to know:

1. the basic tools of computer crypto

2. the programmatic APIs to these tools

3. common programming mistakes that can undermine otherwise secure systems

You will learn the basics of hashing, message digests, public key encryption, symmetric key encryption, certificates, and key management. With each,

you will see programmatic examples, with advice for correct usage.

By Justin Gehtland

Following directly on Cryptography for Programmers, Applied Crypto shows how the cryptographic primitives introduced in the previous session are combined into the identity, confidentiality and authorization systems we use today. We'll take a deep look at certificates, then examine their use in the Secure Socket Layer (SSL) protocol. From there, we'll examine the two competing dreams of distributed identity: PKI and Kerberos.

By the end of this session, attendees will understand the landscape of cryptographic identity systems and the benefits and costs of each. All along the way, we'll look at real code samples to demonstrate the principles, and as an added bonus, we'll finish with an examination of alternative trust models for the truly paranoid.

Java's new Metadata facility introduced in J2SE 5.0 defines a way to attach decorations to classes, fields, methods, and even packages that can be extracted by the compiler or runtime tools to provide advanced functionality. Think of metadata as an extended @deprecated flag, or think of XDoclet++. In this tutorial session you'll learn how Metadata fits in the Java platform (and how it compares to the C# platform). We'll cover how to use the metadata attributes provided in the core J2SE libraries and how to write your own. We'll also show a bit of what's coming in JSR-181, tasked to define standard metadata attributes for web services.

Attendees should be skilled Java programmers ready to see what's possible in the latest release and learn to make the most of it.

XQuery is a new language from the W3C that lets you query and manipulate XML -- or anything that can be represented as XML, such as relational databases. As a Java developer -- especially a server-side Java developer -- XQuery is key to searching and manipulating large XML repositories or performing any XML-centric task.

This talk introduces XQuery. I'll explain the XQuery language; I'll show how to call XQuery from Java; and as the creator of JDOM, I'll also explain when to use XQuery instead of JDOM, and when to use both.

Attendees should have an interest or need in managing large sets of XML, but need not have any past experience with XQuery. After the session, attendees will be able to program XQuery and know which implementations to trust.

By Jason Hunter

In this session I'll take some O'Reilly book content (encoded in Docbook XML) and show various ways that the content can be repurposed and made to sing and dance online using XQuery. I'll show several code scripts each less than a page long that do something interesting -- like combine chapters from various books to produce a dynamic table of contents or index, extract figures and graphics, perform targetted search, and print on demand.

Attendees are encouraged to take the Introduction to XQuery talk before this talk, but that's not a hard prerequisite especially for people who have XPath experience. After the session attendees will hopefully come away with an appreciation for how easy XQuery makes XML manipulation in a real world scenario.

Web Caching is very important for high traffic, high performance web site but few people know all the professional-level strategies. In this talk I'll share some of the tricks of the trade, including advanced tips from Yahoo's Mike Radwin.

We'll start with the basics: using client-side caches, conditional get, and proxies. Then we'll talk about more advanced features: how best to handle personalized content, setting up an image caching server, using a cookie-free domain for static content, and using randomization in URLs for accurate hit metering or sensitive content.

Attendees should have experience or interest in how the web works and in cajoling the web into doing their bidding.

By Jason Hunter

There are many interesting and useful algorithms that people just don't remember or never learned. The Boyer-Moore string search algorithm is one prime example. The randomized skip list is another. Both solve common problems with wonderful flair and finesse -- and performance-wise they blow the pants off brute force solutions. This session covers these two algorithms plus several others. It's like your college algorithms course but with a practical bent and absolutely zero proofs. Extra bonus: The Google PageRank algorithm.

Aspect Oriented Programming (AOP) enables modularizing implementation of crosscutting concerns that abound in practice: logging, tracing, dynamic profiling, error handling, service-level agreement, policy enforcement, pooling, caching, concurrency control, security, transaction management, business rules, and so forth. Traditional implementation of these concerns requires you to fuse their implementation with the core concern of a module. With AOP, you can implement each of the concerns in a separate module called aspect. The result of such modular implementation is simplified design, improved understandability, improved quality, reduced time to market, and expedited response to system requirement changes. Come to this session and learn all about how AOP can help you simplify developing complex systems.

AspectJ (http://eclipse.org/aspectj) is the leading implementation of AOP for the Java programming language. AspectJ is a new language as well as its implementation. The output produced by the AspectJ compiler is compatible with the Java byte code specification. Further, AspectJ is well integrated with the most commonly used IDEs, which makes the Java developer more productive.

This session is targeted at the developer with no or little familiarity with AOP and AspectJ. It will introduce AOP’s concepts and the AspectJ programming language, along with many examples and live coding to solidify the concepts learned.

J2EE has become the main new platform for enterprise application deployment. Good performance is an important business requirement. Supporting this requirement needs application profiling during the development phases and performance monitoring after application deployment. Come to this session to understand challenges and choices in monitoring J2EE applications.

Performance monitoring solutions must work under constraints imposed by the environment. Further, they must balance conflicting requirements such as overhead vs. richness of information. All of these need careful understanding of both requirements and solutions as well as the costs of any tradeoff decisions.

This session presents various tools and techniques available for monitoring J2EE applications. We will consider requirements of performance monitoring solutions in different scenarios. We will also discuss underlying enabling technologies such as Java Virtual Machine Profiling Interface (JVMPI), Java Virtual Machine Tool Interface (JVMTI), JFluid, JMX, design patterns, and aspect-orien

Refactoring allows reorganizing code while preserving the external behavior, while AOP facilitates modularizing crosscutting concerns in a system through use of a new unit of modularity called aspect. Aspect-oriented refactoring synergistically combines these two techniques to refactor crosscutting elements. Individually, refactoring and AOP both share the high-level goal of creating systems that are easier to understand and maintain without requiring huge upfront design effort. A combination of the two -- aspect-oriented refactoring -- helps in reorganizing code corresponding to crosscutting concerns to further improve modularization that is easy to understand, highly consistent, and simple to change.

Aspect-oriented refactoring provides means beyond conventional refactoring techniques. While steps in conventional refactoring modularize code to a certain point, the use of AOP squeezes out the code that cannot be further refactored. Aspect-oriented refactoring offers substantial improvement to the code in a variety of situations: exception handling policies, local contract enforcements, resource management and optimization schemes, concurrency control, worker object creation, and so forth.

This presentation will examine fundamentals of aspect-oriented refactoring, a few common patterns, and a few examples in J2EE space. The presentation features live coding to illustrate the ideas learne

This session, for the Spring beginner, helps you: • Understand dependency injection and inversion of control • Know the meaning of lightweight containers and Spring • Understand the basic pieces of Spring • See core Spring modules in action, including Persistence, AOP, transactions.

Attendees need not know anything about Spring. This session does talk about integration with core J2EE frameworks like JDBC and transactions.

The Spring framework is one of the fastest growing open source frameworks. New job postings are gaining rapidly, and many customers are adopting Spring instead of heavier alternatives. In this session, we’ll introduce Spring. You’ll see how Spring can give you much of the power of EJB, without the complexity or pain.

Spring uses concepts like dependency injection and aspect oriented programming to ease standard enterprise development. Spring developers write plain, ordinary Java objects (POJOs), instead of sophisticated components. In this session, you’ll see a basic Spring application. You’ll also see some details about some of the enterprise integration strategies, including:

This session will help a Java developer choose a persistence framework. After the session, you will • Understand the core strengths and weaknesses of the main persistence frameworks in the Java space • Understand where marketing influences can impact persistence • Know what’s going on behind the scenes to impact the persistence pictures • Answer questions about persistence frameworks that might not be mainstream

This free-form session is intended to help attendees choose or validate a persistence framework. In it, the instructor will take questions from the audience, and tailor the session to the questions asked. Bruce will focus on three persistence frameworks: EJB, JDO and Hibernate. He’ll talk about the evolution of each of the frameworks. He’ll talk about the fundamental design philosophies of each, and what makes each unique and strong.

But understanding technical strengths is not enough in the area of persistence. To make the best possible choice, a developer or architect must also understand the politics of persistence, and the marketing pressures that lead to the success or failure of each

All programming languages have a limited life span, and Java is no different. This is a philosophical session rather than a programming session. Sooner or later, Java will lose its leadership position. This session will explore Java's strengths and weaknesses. We'll try to understand whether conditions are ripe for alternatives to emerge, and what those alternatives may be.

The Java programming language has been tremendously successful. Many of the roots of its success may be surprising to the audience. But every major programming language has a limited life cycle. While it’s true that Java and .NET seem to be the only games in town, some alternatives are beginning to emerge.

In this session, we’ll discuss some of the limitations of the Java language, and the impact that they might have on the productivity of Java developers. We’ll then look at some of the innovations around other frameworks and languages, and some of the features of those languages that boost the productivity of other non-Java developers:

• Typing, and why it matters

• Code blocks and closur

Ruby recently enjoyed its tenth birthday. Instead of cake and candles, the community celebrated by releasing a wave of new libraries and frameworks that make Ruby programming even easier. This talk features some of the best of these, as we explore Ruby.

We'll spend about half the session getting to know Ruby: the syntax, type system, blocks, iterators, and so on. Then we'll dive in and develop some real-world code using web services, RSS, and databases. If you want to come to the Rails talk, and you're not that familiar with Ruby, this talk is a good starting point.

The Ruby on Rails framework has exploded onto the scene over the last few months. Propelled by some genuine benefits, and fueled by a whole lot of controversy, Rails seems here to stay. So, is it a Java killer? (No.) Is it a great way to develop certain classes of web application? (Yes.) Does it really deliver the 10-fold increase in developer productivity that some have claimed? (It depends...)

If you can't help thinking that there must be an easier way of developing web projects, come and join us as we construct an MVC-based Ruby on Rails application using the very latest libraries and tools. You'll get a taste of Ruby, and also a feel for some of the power and productivity gains offered by this remarkable framework. You'll need a grounding in Ruby to get the most from this talk; if you're not already a Ruby developer you might want to attend the Facets of Ruby talk before coming to this one.

Are you frustrated by experts who can't tell you what to do, or by junior team members who refuse to see the big picture? How can you best develop careers: both yours and those of your teammates and managers? How can we learn to apply experience more effectively, and why do the many approaches designed to tame complexity actually end up increasing it?

Dave Thomas, of The Pragmatic Programmers, describes the solutions to these and other problems as he turns the Pragmatic Spotlight (and a good dose of twisted humor) on formal learning models, the Nursing profession, and streamlining sheep.

Every now and then, it's really helpful to be able to generate a new Java class at runtime. Some problems just can't be solved any other way. It's one of those troublesome tasks: it's fairly tricky to do, and you only need to do it occasionally—but when you need it, you really need it (and usually you need it yesterday). So you have to start essentially from scratch, learning about how to do it on the fly, under pressure.

This talk is designed to help. You may not face this problem for a while, so there's no point focusing on the arcane details that you'll soon forget. Instead, I'll give you what you'll need to quickly come back up to speed when the time comes. You will see some real bytecode generation, but more importantly we'll discuss the types of problems where runtime code generation can save the day, the variety of tools and techniques that are available, and a step-by-step approach to getting the job done. Finally, for those who may be working with more dynamic languages, I'll show how powerful runtime code generation can be when it's easy. We'll start simply, but before we're done we'll be pretty de

The Java Collections framework is a cornerstone of Java development. It's been a part of J2SE for six years now. Every Java developer knows it—how to create Lists, Maps, and Sets, how to put things into them and take things out, and how to iterate over the contents. But there's a lot more to the collections framework than that -- and very few programmers really know how to exploit the power that's just under the surface.

The basics of the collections classes are so simple that many developers haven't even thought to look for the additional power that's there. And it's not just built-in capabilities, either. The design of the collections framework makes possible several powerful techniques and patterns that can magnify your productivity, as well as helping you build systems that are efficient and scalable.

It may seem strange to give a talk on a framework that every Java programmer already knows. But in every project I've worked on for the past six years, I've seen a lot of code that uses the collections poorly. More often than not, that code was written by skilled programmers with significant Java experienc

Most of the time, Java's automatic memory management works really well—it's one of the things that makes programming in Java a pleasant and productive experience, and it's nice that we don't have to worry about managing memory manually. However, although it's usually nice to ignore memory management, occasionally we have to pay close attention. Sometimes we need to take control of certain aspects of memory management. Sometimes Java programs do exhibit memory leaks, or unacceptably long garbage collection pauses, or very poor overall performance. But because Java's memory management is supposed to be "fully automatic," it can be difficult to find out what's really going on inside the VM.

Java memory management is just like most labor-saving simplifications: it works well most of the time, but for the weird edge cases when it doesn't work quite right, it can be a nightmare. This talk opens the hood, examining the inner workings of Java's memory system, including allocation and garbage collection. We'll look at how to control the memory system and interact with it, what's costly and what's not, how to tune the garbage collector and when to switch to a different GC algorithm, and other topics.

With the sudden importance of Ajax, it's time to take JavaScript seriously. That means learning it the right way: looking at the fundamentals of the language and surveying its strengths and weaknesses, instead of just copying other people's poorly written examples.

JavaScript got a bum rap. It's almost universally derided among serious programmers for being a toy language, or for its strange characteristics, or bugs, or slowness, or because it's only good for adding useless window dressing to web pages.

But JavaScript is actually a very nice little language which is popping up everywhere these days (not just in Ajax apps). Sure, JavaScript is quirky, but its problems are mostly due to history, association, and misunderstanding. Especially misunderstanding. Let's face it: most developers learned JavaScript by looking at examples in web pages they found online, and few of those examples are paragons of JavaScript style. Other developers learned JavaScr

We've been writing web applications now for 10 years, and they're still no fun. They're awkward and clumsy to write. Internally, they're overly complicated (which almost invariably means that they're buggy). Meanwhile, they're usually too primitive externally. To put it another way: the web programming model is so cumbersome for programmers that the users pay—through reduced features, clumsy interaction, bugs, and poor performance. There's a better way. I know -- who needs another web framework? But Seaside makes even Rails look primitive.

Seaside represents a new generation of web frameworks. Using it, web development is simple. A little code goes a long way. The code is simple and clear. There are powerful development tools that magnify your productivity. You can focus on making your web application good rather than having to strive with all your might just to make it work. It might not be perfect for your situation—it's written in Smalltalk, for one thing, which presents a barrier to adoption in many organizations. And it's not quite as scalable as more traditional web frameworks. But for most applications, it would drastically reduce the development effort while also increasing the usefulness and robustness of the applicat
