Could not passivate; failed to save state

Question

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:
11:53:50,390 WARN  [AbstractInstanceCache] failed to passivate, id=f373o8gy-s

        ... 6 moreMy 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?

Answer 1

So those are the ONLY fields in your bean? Does the class declare a ThreadLocal field or is a
super-class that declares a ThreadLocal field? If not, it could be a JBoss bug. I'd recommend
posting on the JBoss forum.
