You probably have that class org.jboss.portlet.hello.HelloWorldJSPPortlet defined in 2 different places.

Hai,

Thanks for the reply. I could figure out that i was having a mismatch with different versions of jar files. One used during the build and the other in the server.

Well i have another problem now.
When ever i am trying to make a hot deploy, by touching the web.xml in the server. i am getting the following exception:

:15,683 INFO [DefaultLoadEventListener] Error performing load command

4. DefaultLoadEventListener error when deploying

antoine_h Jul 15, 2007 3:55 PM (in response to explorer)

I have just got the same.

not when touching the web.xml (which is not a very good way, as far as I know... depends of which war...).

I search on that and will reply when I find it.
