javax.rmi.MarshalException from servlet trying to store sess
Hi,
Just realized this was probably the better forum in which to post this message.
I am trying to store the handle to my stateful session ejb in the HttpSession, so each web session has its own stateful session EJB. Here is my code: (in doPost)
--------------------------------------------
Bobo bobo = null;
// if this is a new session, create a bobo bean for it. If not,
// restore this session's bobo bean
if (request.getSession().isNew() == true) {
try {
InitialContext ic = new InitialContext();
Object objRef = ic.lookup("ejb/bobo");
BoboHome home = (BoboHome)PortableRemoteObject.narrow(objRef, BoboHome.class);
bobo = home.create();
} catch (NamingException ne) {
ne.printStackTrace();
} catch (CreateException ce) {
ce.printStackTrace();
}
} else {
Handle handle=(Handle)request.getSession().getAttribute("boboHandle");
bobo =(Bobo) handle.getEJBObject();
}
... servlet code executing the bean...
// store the bean reference
Handle handle = bobo.getHandle();
request.getSession().setAttribute("boboHandle", handle);
out.close();
-------------------------------------------------
I am getting this exception when I hit the page... seems to have trouble with the setAttribute.

Any ideas? What am I doing wrong?
