[jboss-user] [EJB/JBoss] - Re: jboss throws an exception when casting a proxy class

Jaikiran,

First of all, thank you for your suggestion.

No, I do not have the bean interface in more than one jar (at least not in the files I have deployed). I have read the document for which you sent a link and also followed the suggested jmx-console steps to verify if the bean interface appears in multiple places. This is what I found:

>From the documentation and jmx's output I would say that I only have one instance of my test bean (ConfigurationBean). 

I have more information but still do not know how to correct the problem. :(
