Hi all,

i have an application that runs on was-6.1
also there is a plugin which uses AspectWerkz and injects something into the application at runtime. Now the problem i am facing is....

AW::WARNING - could not load class [com/infosys/j2ee/core/BaseException] as a resource in loader [com.ibm.ws.bootstrap.ExtClassLoader@406e406e]

and due to this injection does not take place

any idea about the issue.it is very urgent.
Thanks

It's a classpath issue, it looks. Not sure why it couldn't be loaded.

You've got it on the extensions classpath. Is there any way you could repackage the application and place this file in the lib directory of the war? What about moving the file to the WebSphere \lib\app directory?

Here's a tutorial on understanding WebSphere and J2EE classloaders. Maybe it'll give you some insight into your problem:

Demystifying WebSphere Classloaders: Loading Java Classes at Runtime

Good luck!
