I was trying out an example from EJB 2nd ed... I have correctly deployed the
entity bean in weblogic... the database is up and running and the db pools
have been correctly created and initialized... when i try to run the client,
i get the following error... I recreated the jar and redeployed it but to no
avail... any help would be appreciated...
thanks in advance
r
p.s: the code (1st two lines) on which it chokes is:
Context jndiContext = getInitialContext();
Object obj = jndiContext.lookup("CabinHome");
lookup throws the following error:
javax.naming.ConfigurationException. Root exception is
weblogic.rmi.server.ExportException: A description for
com.titan.cabin.CabinBeanHomeImpl was found but it could not be read due to:
[Failed to find a stub for [class com.titan.cabin.CabinBeanHomeImpl]

weblogic.rmi.StubNotFoundException: Failed to find a stub for [class
