Re: Problem with ejb and struts

It looks as though there is problem in the specifying the name of the bean
to look for  -"java:comp/env/ejbUserManagement"

first of all I think u can reference a bean using
"java:comp/env/ejb/userManagement"  only inside the another bean code

For u to access the bean out side - give "userManagement" as the <Jndi-name>
in the descriptor file

Subject: Problem with ejb and struts


Hi!
I have a problem accessing the InitialContext in the action classes. I'm
using struts blank with ejb and when I lookup the ejb they cant be
found!  The enviroment returns an empty Context..

..code from an Action class..

Context ctx = new InitialContext();
Object homeObject =
m_ctx.lookup("java:comp/env/ejbUserManagement");
home =
(UserManagementHome)PortableRemoteObject.narrow(homeObject,
UserManagementHome.class);



The server which I am using is Orion 1.5.2

the ejb-jar.xml should be correct but I am not sure about the
Refences in Web.xml

This is my web.xml..
