hello
my session bean is "Viewer",my entity bean is "Authors",both of them are within the same jar file named "Viewer.jar".i create a
test client by using jb6,in this client i access the session bean by using remote interface,it works well,but when i try to access the entity bean in the session bean by the local interface,the jb6 throw a "NameNotFoundException".following is the details:
my deployment descriptor:

in my session bean,i specify:
...............
..............
Context ctx=new InitialContext();
Object ref=ctx.lookup("Authors");
................
..............
i think that i should add the "ejb-local-ref" tag to the deployment descriptor,as follow:
