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?
