Blogging Roller

Survey says 80% of New Relic's Java customers choose open source app servers over expensive bloat-ware.

Server wars: Open-source Java vs Weblogic and WebSphere | Software, Interrupted - CNET News: Overall, it's not surprising that users who are deploying their applications to the cloud are more likely to use open source, if for no other reason than that licensing is far simpler. Additionally, there are Amazon Machine Images (AMIs) available for most open source stacks, making it very easy to choose open source over a traditionally licensed application server.

In my quest to get Roller running on the latest in Java EE servers, the last server I tacked was the WebSphere Application Server. Unlike Glassfish and JBoss, WebSphere's Java EE 6 offering is not available in final form yet. Java EE 6 support is coming in WebSphere 8. So, for this exercise I used the WebSphere 8 beta, which was made available in July 2010. In this blog I'll describe how I approached the problem what I learned along the way.

It's hard to believe, but I've been dorking around with Roller, the blog software that powers this site, for almost 10 years now. I started in summer 2001. In the past couple of years, I've had a lot less time to work on Roller. I devoted some of that time to mentoring student developers, which was fun and rewarding. I also spent time making Roller more consumable for developers by making it easier to build, run and deploy to modern Java app servers, which was not really fun but was definitely educational, bloggable even.

On the last day of 2010, I made available the third release candidate for Apache Roller 5.0. The main difference between this new candidate and the previous one is that the new RC3 runs on Java EE 6 servers: Glassfish 3, JBoss 6 and Websphere 8 (currently in beta). Making this happen took a lot more work than I expected and I'll blog about that over the next couple of weeks as it is an interesting case study in Java EE 6 portability.

Here's the announcement:

Apache Roller 5.0 Release Candidate RC3 is now available for testing.
Note that this is NOT a release of the Apache Software Foundation or
anybody else; this release candidate is for testing purposes only and
not recommended for production.

The biggest change in RC3 is the new support for Java EE 6 application
servers: Glassfish 3, JBoss 6 and Websphere 8 (beta). I've been able
to verify that Roller runs on all of those servers, and I updated the
installation guide to explain in detail how you install on Glassfish,
JBoss and WebSphere.

If you would like to help out then please test RC3, discuss the
problems you encounter here and file specific bugs with steps to
reproduce in the Roller JIRA bug tracking system.

Thanks,
Dave
