thank you for the info but everything I found there tells me that the =20=

problem is related
to some reference in the RMI server that is not unbind or unexported =20
properly.

I tried the following code in the RepositoryStartupServlet to see if =20
there were some remote object that weren't unbind or unexported but I =20=

couldn't find any,
I inserted this line after the last line of code in the method =20
unregisterRMI():

	try {
                 String[] names =3D registry.list();

                 log.info("names list lenght: " + names.length);

                 for(int i =3D 0; i < names.length; i++){

                     try{
                         log.info("trying to unbind: " + names[i]);
                         registry.unbind(names[i]);

                         log.info("trying to unexport remote obj with =20=

name: " + names[i]);

                         Remote remoteobj =3D (Remote) =20
registry.lookup(names[i]);
                         UnicastRemoteObject.unexportObject(remoteobj, =20=

true);

                     } catch(Exception ex) {
                         log.error("Exception " + ex);
                     }
                 }
             } catch (RemoteException re) {
                 log.error("Remote Exception getting list: " + re);
             }


but the list is empty!

so at this moment I don't know whatelse to try...

is there any other place in the code where are some objects being bind?


thanks one more time!


cheers,

bruno coelho
