peterj Aug 26, 2008 12:19 PM (in response to patwary_shiva)Which version of JBossAS are you using?
Are you referencing the jar files in application.xml?
I am not sure in which version of JBossAS it started to automatically recognize the lib directory. -

11. Re: Classloading issue (loading class from another jar)
peterj Aug 27, 2008 2:40 PM (in response to patwary_shiva)Is this stack trace different than what you started with? You originally wrote "unable to acces class in our custom jar" which I interpreted to mean you were getting a ClassNotFound exception. The stack trace you posted is another issue entirely. I have no idea how to convince Struts to call your custom convert method.
