[jboss-user] [EJB 3.0] - SerializationException when attempting to activate a statefu

[redyz]

Hi,

I got the SerializationException problem when JBoss 4.0.4 tries to activate a stateful session bean that was passivated (and hence serialized to a file unser [JBOSS-DIR]/server/all/tmp/sessions directory). I am not using enum. The error is as follows:

Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: org.jboss.serial.exception.SerializationException: Could not create instance of org.hibernate.ejb.QueryImpl - org.hibernate.ejb.QueryImpl

Somehow the deserialization in JBoss is not working during activation??

btw my server.log looks like this:
