Hi,

I work to integrate Spring in a jboss-3.2.1_tomcat-4.1.24 base app.

I want to remove the ejb's to use JavaBean , I have integrate a Region Javabean but on the deploy in Jboss I have this error.

(I have already check If I have Hibernate3 everywhere)

I think you have been bitten by a classloading bug. JBoss uses a special kind of classloaders (i.e. Unified ClassLoaders - UCL) and in your case, the CGLIB is probably loaded from a different classloader then your application and that's why the error.
I suggest to read the docs for JBoss and see what options you have in configuring the classloader (especially when dealing with Tomcat you can turn on/off the default java delegation IIRC).
Also, try upgrading JBoss since 3.2.1 is quite old and it might have some bugs.
