Central Ohio Software Symposium
July 25 - 27, 2008 - Columbus, OH
President of Gist Labs
Agile/Kanban coach, REST architect, software craftsman
John D. Heintz is a husband, father, developer, Agilist, entrepreneur. After studying electrons in college, John's intuition led him to pursue software, and he's been a digital craftsmen since. Always seeking solutions with higher leverage and deeper simplicity has led John to important methods and tools. John's approach to building systems and teams started with leading his first Scrum team in 1999, included XP and TDD, and now Agile and Lean methods are part of his daily work and consulting. John has built single-source hyperdocument SGML publishing systems, a version control CORBA/Python CMS, an AspectJ dependency acquisition framework, added test automation to many Java and .NET systems, coached a 100-person Agile/Lean game studio, and built RESTful Web integration systems. John has launched his own company, Gist Labs, to further his focus on essential innovation.
REST is a description of how the Web works, what use is that to developers just trying to build or integrate applications?
This presentation introduces REST, explains the key differences/constraints, and then highlights how these concepts can improve key parts of application and service development: * scalability, integration, evolvability

In this session you will learn about the Glassbox open source troubleshooting and monitoring tool. Glassbox enable detection of common application problems such as database failures, slow operations, thread contention, and excessive distributed calls. Glassbox enables low overhead monitoring and troubleshooting without needing to "bake in" instrumentation up front.
Glassbox provides an intuitive Ajax Web interface, an automated installer and concise summaries of common problems out of the box. Glassbox focuses first on highlighting the underlying cause of a problem without requiring a person to sift through volumes of profiling information. Glassbox also supports customization and detailed analysis for deeper investigation. Under the covers, Glassbox uses JMX and Aspect-Oriented programming to discover applications, track performance, and automatically diagnose common problems in Java applications.
You will see how Glassbox can be extended easily (with XML, AspectJ and Spring AOP) to providing a useful foundation for customized application monitoring. Glassbox is open source and can be downloaded freely from http://www.glassbox.com/.
Java's Annotations provide a way to add data to program elements. Annotations are used to configure containers, describe persistence configuration, set security roles, and are defined by nearly every recent JSR standard. This presentation explains the processing options available for consuming Annotations and demonstrates the techniques with live code demonstrations.
The presentation: * introduces Annotations and how to create custom Annotations, * surveys the techniques that can add implementation effects from Annotations (code generation, bytecode transformation, runtime reflection), * demonstrates adding behavioral effect to an example with APT, Reflection, Javassist, and AspectJ, * wraps up with best practices for using and defining Annotations.
No prior experience is necessary, and attendees will learn how to define and to provide behavior for custom Annotations in their own systems.
This presentation introduces and demonstrates Liquibase: a new Java tool to support automating database refactoring and deployment.
Agile Database tools and techniques have been evolving to catch up with the existing support for source code. Many projects struggle to keep external databases (and DBAs) in sync with rapidly changing and tested source development.
Support for Agile Database development needs to include tools support for the following areas: * Database Refactorings * Schema Version Control * IDE Support * Scripted tools (Ant, Maven, command line)
Liquibase is an LGPL-licensed Java tool for tracking, managing, and applying database changes. Liquibase enables the database schema, reference data, and data change scripts to be managed as effectively as source code on Agile projects: * the CI build doesn't break from forgotten SQL script runs * developers don't have to coordinate check-ins/outs with each other * embedded or external databases can be managed with the same scripts * databases can be automatically upgrades, or SQL generated for review
This presentation introduces these topics and demonstrates Liquibase with an example application showing Spring Framework, Ant, and continuous build integrations.
