Tapestry and WebSphere Portal Server 5.1

[Ryan Wynn <rw...@us.ibm.com>]

After about a weeks worth of work today I was able to get a running 
tapestry JSR-168 portlet to work in WebSphere Portal.  I had initially 
gone down the path of trying to integrate Tapestry 4 with Portal Server 5. 
 This didn't work because Portal Server 5 runs jdk 1.3.1 and Tapestry was 
trying to load a 1.4 class, specifically java.util.IdentityHashMap 
(Created bug Tapestry-452 on JIRA).  Then I went down the path of 
installing WebSphere Portal 5.1 which uses jdk 1.4.2 (most of my time 
being spent here).  This got me further, but not quite there.  I got an 
exception involving tapestry annotations.  This ended up being an easy 
fix.  Remove tapestry-annotations-4.0.jar from the classpath.  I should 
have known this since I'm using jdk 1.4.2 but it may be beneficial to add 
to the documentation to only include this jar if you are using jdk 1.5 
(for people like me that blindly include all framework jars when trying to 
get a sample app running).

Otherwise, everything was good.  Looking forward to experimenting with 
tapestry in the portlet world.
