-------------------------------------

Hi Christian,

I'm actually looking at it right now :)  

I have tested your fix, and it does solve the initial issue.  What I'm seeing is that searches from the hotel search input box is failing with the same basic error.

The problem is that this goes through the "ClientSideInterceptor" not the "SessionBeanInterceptor".  So your changes are not processed.  

One concern I have with your change is that it basically reinitialized the interceptor every call.  It might not be too costly, but it could have other implications.

Another path I'm going down is that the issue is related to the weblogic auto generated classes that it creates from the EJBs.  This might be why reinitializing every time seems to help.  The first time through the interceptors are caching the original bean classes, but when called the generated ones are in there.

In either case I think that postConstruct is not being called, and from what I'm read and debugged is that weblogic is pretty bad at swallowing errors and logging output.  Also that these errors can cause processing of annotations to stop.  

I am trying to get something for this out for 2.0.2.GA - the timing is tight - but hopefully it is will come down to a weblogic deployment option ;)

Thanks,
-Jay

> There is a know issue with weblogic and support for EJBs that use variable arguments.  This is documented in the reference guide for more details.
> I've attached the full stack trace from the console.
> The main errors revolve around EJB3 timers - there may be a way to disable timers through the weblogic.xml deployment descriptor, or perhaps a different file. 
> There are other warnings around EJB synchronization, but they may still function.
> If solved the reference docs should be updated.
