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.

Spring offers developers a simpler, more robust method for configuring applications. These benefits extend to security through the ACEGI framework. ACEGI makes the otherwise daunting task of securing your application logical and straightforward. More importantly, through its support for single sign-on provision through Yale's CAS system and its ability to provide instance-level authorization, Spring extends the common security model of most J2EE apps beyond what they are traditionally capable of.

In this session, we'll explore:

• configuring ACEGI to authorize against an in-memory user list, a database, and a JAAS login module

• page level authorization

• method level authorization

• instance level authorization

• forcing HTTPS connections to secured sites

• impersonation using the RunAsManager

Learn to use Spring AOP, aspect injection. and AspectJ integration.

Spring provides powerful support for Aspect-Oriented Programming (AOP), via

Spring Advisors Dependency Injection for Aspects Integration with AspectJ

In this session you will learn to use Spring AOP in real-world settings. We'll start with the basics of programmatic pointcuts, advice, and joint points. Then, we'll integrate these into the application Spring-style, using Dependency Injection.

With the basics out of the way, we'll move to meatier questions, including:

How (and when) should I step up to AspectJ? How are Aspects implemented, and what are the performance implications? What are the alternatives to Aspects?

Attendees will get more out of this presentation if they have a basic knowledge of Spring and Dependency Injection.
