Hi Andrea, -----Ursprüngliche Nachricht----- >Von: Andrea Broglia [mailto:[EMAIL PROTECTED]] >Gesendet: Freitag, 16.

But this should have been set correctly by the StatelessSessionInstanceInterceptor (see your xml-descriptor), before. Puzzling. Which version of jboss are you using? Could you trace the container from the ContainerInvoker to the ContainerInterceptor? Otherwise, you could send me your source/jar such that I will do it ... Best, CGJ -- -------------------------------------------------------------- To subscribe: [EMAIL PROTECTED] To unsubscribe: [EMAIL PROTECTED]
