Can't using J2EE java mail?

Question

hi all,
Here is a problem that I have with my the usage of Java Mail Session
that i set up in weblogic. I use weblogic 8.1
When I do the JNDI lookup to the mail session (set up in the weblogic
admin interface), it looks that the lookup itself is ok but when i do
the casting, it doesn't work. Have a look at my code and the trace
produced :
writed an external client,follow:
<myCode>
Properties h = new Properties();
h.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory
h.put(Context.PROVIDER_URL,"t3://localhost:7001"); // provider url is
right
h.put(Context.SECURITY_PRINCIPAL,"weblogic");
h.put(Context.SECURITY_CREDENTIALS,"password");
Context namingContext = new InitialContext(h);
Session mailSession = (Session) namingContext.lookup("jndi/mail");
</myCode>
<trace>
javax.naming.ConfigurationException. Root exception is
java.rmi.MarshalExceptio
n: error marshalling return; nested exception is:
java.io.NotSerializableException: javax.mail.Session
java.io.NotSerializableException: javax.mail.Session
<<no stack trace available>>
</trace>
I can understand the exception as javax.mail.Session doesn't implement
serializble. But How do I have to do to make it work, then? Because what
I do is just how it's explained in the weblogic doc. Is there a mistake
in the do? Do I have to cast to somethig else?
Any help would be very appraciated.
Thanks.

Try this on the server side not from external client - that should work fine.
If you need this from an external client, since the java.mail.Session object is not serializable - you can also implement an EJB and have your client lookup the session bean and send the data to the server and have the serverside session bean implementation create the mail session and interact.
