[jboss-user] [EJB 3.0] - Exception during passivation a stateful session bean

[rockerman]

Hi,

I have a problem with an exception during passivation a stateful session bean that only occurs in product environment. The server produces the following stack trace:

I think the problem is that an instance variable of the session bean (an ArrayList) could not been passivated. I've tried to reproduce the error by setting the 'overager-period' and the 'max-bean-age' properties of the 'Standard Stateful SessionBean' element in the 'standardjboss.xml' file, but as long as we're using EJB 3 I had to configure the 'ejb3-interceptors-aop.xml' file I think. But I'm not sure which properties I have to change to activate an early passivation of the stateful session beans. Does someone have a solution for this?

Thanks
