Hi everyone,

I'm using:
Eclipse 3.0
Xdocklet (build430) to generate interfaces etc...
Jboss 3.2.3

I really need some help regarding a problem i'm having with a no such method error. Strange thing is that this occurs randomly after a successful build and deploy to jboss 3.2.3 has completed. Well at least it looks like it's random.

The error occurs after I have logged into my webapp and proceeded to my "process domain" actions.

This only occurs in one domain as well - when I add entities to other domains (in other packages) then it never occurs.

Find the stack trace snippet below :


HTTP Status 500 -


type Exception report


description The server encountered an internal error () that prevented it from fulfilling this request.


javax.servlet.ServletException: Unexpected Error
java.lang.NoSuchMethodError: Ljava/util/Collection;


This business delegate is a session bean and the Facade is a "POJO". When I decompile the classes however, the methods are there. Also I have checked the parameters and return types and all looks fine.

A shortcut way I have been using to fix this is to clean output folders and build also regenerating my interfaces for my session beans and entity beans and also regenerating their xml files (like the deployment descriptor etc...) After doing all this it sometimes works , sometimes it doesn't. Like I said - Random.

Thanking you in anticipation.
