Hi all,
I have a constructor in DAO(Data Access Object) which gets
InitialContext.
I am using this DAO in my EJB.
its working fine if i use this DAO independently.
The problem is when i use this DAO in my EJB it couldn't get me the context
and giving the following exception.
java.rmi.RemoteException: Weblogic RemoteException(weblogic.rmi.ServerError)
remapped from:weblogic.rmi.ServerError: A RemoteException occurred in the
server method
- with nested exception:
[java.lang.NoClassDefFoundError: javax/naming/NamingException]; nested
exception is:
