Passivate problem + SerializationException

[lisaanm]

Hi.,
I'm getting passivate problem (sometimes after 5 mins / 10 mins) together with Serialization exception.

Here's the stack trace:
Code:

Any help is highly appreciated.

Thanks

Hi

First thing to check is that all of your entity and SFSB are Serializable, and have defined a serialVersionUID.

Was this all you had to do to solve the passivation problem? I'm having the same issue and all of my beans are serializable and define the default serial version stuff...
