Hi,

I'm usign 4.0.5/EJB3 and an independent Tomcat 5.5
Ububntu 5-10 java 1.5.08.

Using StatelessSessionBean with a BusinessDelegate as a facade.

Every now an then, sometimes after re-deploying, sometimes after
restarting jboss, a call to Business-Method (isUserAuthorized) from
my tomcat application (web-service) gives this error

Caused by: java.lang.ClassCastException: isoa.users.bean.UserContext
 at $Proxy15.isUserAuthorized(Unknown Source)
 at isoa.users.bean.UsersServiceBd$3.run(UsersServiceBd.java:91)
 at isoa.commons.bean.AbstractBizDelegate$EjbRun.runWithRetries(AbstractBizDelegate.java:150)
 ... 37 more

UserContext class is in the class-path, I checked the version is
always the same in my client and in my server, etc., etc..., all
seems pretty ok.

Sometimes after calling the method a second time or just re-deploying begins to work OK again.

Any Idea where to look for, or what is happening

Thanks in advance
