Question

I use Eclipse with Websphere server .

I need to add a session listener . I added the class SessionListener.java in the package net.test . When I add the < listener > tag to the web.xml file , I get the folowing error :

Distribution of configuration failed.  See log for details.

This is a (nasty) bug in WASCE. It should have been "file:///C:/Program Files/IBM/....". The file:// is here the protocol which was missing due to the space in Program Files. The IBM guys should have quoted path names, but they apparently overlooked it.

To fix this problem, either install WASCE in a path without spaces, or upgrade to the latest version available.
