My ramblings on Java EE, Java SE and the crazy World of technology in general.

TSSJS 2011 Round-Up

I spoke at TSSJS 2011 March 16-18 in Vegas. TSSJS 2011 went extremely well and so did my talks. I think the TSSJS 2011 agenda, quality of content/speakers and buzz was the best in years. The new TSS editor Cameron McKenzie did an admirable job at putting everything together.  Some of the notable speakers included James Gosling, Steve Harris (SVP Oracle), Adam Messinger (VP Oracle), Patrick Curran (JCP chair), Rod Johnson, Bill Burke, Adam Bien and Kirk Pepperdine.

I started the conference with a 5-minute lightning round presentation on Resin 4, the Java EE 6 Web Profile, Caucho vision, history, thought leadership, values, global footprint and growing customer base. The presentation seemed to go over well with a number of existing customers and developers reaching out to us afterwards. The first session on the first day of the conference I did was my enterprise caching talk titled “Effective Caching Across Enterprise Application Tiers”. The talk covers the different flavors of caching in the web (HTTP), presentation, application, domain, infrastructure (persistence) and resource (database) tiers using mechanisms like proxy caching (especially as supported by Resin), JSF/CDI @ApplicationScoped, @SessionScoped, @ConversationScoped, @ViewScoped, @RequestScoped scopes, passivation, EJB pooling, EJB thread-safe singletons, extended persistence contexts, JPA first (transactional) and second (shared) level caching, database connection pools, prepared statement caching, JCache as well as distributed caching APIs like Coherence, Terracotta, GigaSpaces, Infinispan, EHCache, JCS, SwarmCache and OSCache. The talk was very well attended, the Q&A was good and I got great feedback afterwards. In the evening, I participated in the “Meet the Authors” event. TSSJS gave away two copies of EJB 3 in Action (I am currently working on the second edition) and I signed both copies for the winners. I had a few engaging conversations on topics like EJB/Spring, authoring and the JCP during the course of the evening.

I started the second and busiest day of the conference with a panel titled “The Java Community Process: What’s Broken and How to Fix It”. This was a panel with Patrick Curran, James Gosling and me, moderated by Cameron McKenzie. We discussed the need for reforming the JCP, greater transparency, the Apache Harmony licensing issues, more non-Oracle spec leadership and more participation from non-vendor affiliated independents. We all agreed that many ills in the JCP can be cured through greater interest and participation from the developer community. The panel generated a great deal of interest, attendance, participation and feedback. After lunch, I gave my “A Quick Tour of the CDI Landscape” talk. The talk is a broad overview of the vibrant CDI landscape composed of implementations, supported runtimes, portable extensions and tools. I discussed Weld, CanDI, OpenWebBeans, GlassFish, JBoss AS, Resin, Geronimo, WebLogic, WebSphere, Tomcat, OpenEJB, TomEE, JOnAS, Seam 3, Apache MyFaces CODI, the ZK Framework, Arquillian, Forge, JBoss Tools, Eclipse, NetBeans and IntelliJ. The audience was great and I had some lively discussions afterwards. Later in the afternoon, I did my Java EE testing talk titled “Testing Java EE 6 Applications: Tools and Techniques”. The talk covers end-to-end testing along the entire Java EE stack including Servlet 3, JSF 2, EJB 3.1, JPA 2, JAX-WS and JAX-RS using existing and emerging tools like JUnit, HttpUnit, HtmlUnit, Cactus, Selenium, JSFUnit, embedded containers, embedded databases, Arquillian/ShrinkWrap, Resin JUnit integration support and soapUI. The talk was well attended and I got excellent feedback for the talk. It was only somewhat surprising that folks don’t realize how robust Java EE testing is with the latest release and tools like Arquillian. In the evening, I participated in the “Ask the Experts” session which also went very well.

The last day of the conference I presented my talk titled “An Introduction to Seam 3″.The talk discusses the relationship between CDI, Weld and Seam 3 as well as covering all the Seam 3 modules such as XML configuration, persistence, Faces, Servlet, JMS, REST, JavaScript remoting, security, internationalization/localization, exception handling, mail, cron, document generation, Spring interoperability, Wicket, GWT, Drools, jBPM, JBoss ESB and so on. Since it was towards the end of the conference the attendance was relatively sparse but the Q&A session was very good with a lively audience.

A number of folks asked for the slides and demo code, so the materials for the talks is posted here.
