WASCE 2.1  Configuration Issue in Eclipse 3.3

This is the issue which I faced while configuring WASCE2.1 in eclipse europa. Just want to share what's the issue I faced.

WASCE2.1 causes NullpointerException during deployement. 

I installed Websphere community Edition 2.1 (WASCE2.1) and tried to deploy a small dynamic web project using eclipse. First I tried thro' the eclipse latest version GENEYMEDE. But I couldn't deploy successfully. After that I came to know that WASCE Eclipse plug-in doesn't supports Eclipse Ganymede platform.

So I tried to deploy thro' Eclipse Europa. Still I couldn't deploy successfully.The server starts up fine. But am getting NullpointerException while publishing.

Solution

Community Edition uses a Geronimo specific deployment plan(geronimo-web.xml) But the installed plugin didn´t generate the geronimo-web.xml file when defining a Dynamic Web Project with WASCE as its runtime.

so, I tried to place geronimo deployment descriptor file in /WebContent/web-Inf/ folder. Still it doesn't work. 

Below is the error which I got while publishing the WASCE server.

!ENTRY org.eclipse.wst.server.core 4 0 2008-09-05 23:01:50.285

!MESSAGE Could not publish to the server.

what was happened is my eclipse is configured to Java.version=1.6.0_07. Under this configuration eclipse is not generating the geronimo deployment descriptor. After configuring eclipse to Java version 1.5, eclipse generated the geronimo-web.xml and the deployment went successfully.
