[jboss-user] [EJB/JBoss] - Could not passivate; failed to save state
Hi guys
I'm using ejb with a web application on jboss 4.0.5 with jdk 1.5 and i'm getting
this exception:

My code (Session bean statefull):
| protected transient Log log;
| private transient IdentitySession identitySession;
|
| public void ejbPassivate() throws EJBException, RemoteException {
| log.debug("bean passivating... ");
| log = null;
| identitySession.close();
| identitySession = null;
| }
|
the attributes are transient because i had read somewhere that like that i could avoid
serialization problems. but they remain, i've tried with and without them and the
output is the same.
IdentitySession is a non-serializable object and Log is a interface from commons logging
also non-serializable.
can anyone help?
