Re: Entity bean never passivating

[Bryan \(Mailing Lists\)]

Here is how I implement isModified:

    private transient boolean isDirty;
    public boolean isModified() { return isDirty; }
    public void setModified(boolean flag) { isDirty = flag; }

    public void ejbStore() throws javax.ejb.EJBException,
java.rmi.RemoteException {
        setModified(false);
    }

    public void ejbLoad() throws javax.ejb.EJBException,
java.rmi.RemoteException {
        setModified(false);
    }

    // All of my "set" methods follow this format
    public void setXXX(String xxx) { setModified(true); this.xxx = xxx; }

Is this the correct implementation?

Also I should add that my entity beans were passivating correctly in JOnAS
2.1, but when I upgraded to 2.2.4 the other day, I started to have this
problem (with no changes to my code, except the addition of the
<passivation-timeout> value).

Lastly, my entity beans DO eventually passivate, if I shut down JOnAS or
execute "JonasAdmin -sync".

Thanks in advance,

Bryan
