Re: [jetty-users] Embedded jetty-all 8.1.x JNDI + Atomikos + OpenJPA 2.x
|
Will,
java:comp/env is a namespace related to webapps. You don't have a
webapp, just a handler.
Therefore, put your jndi bindings into the global namespace (rather
than the Server instance's namespace), and then look them up from that
global namespace.
So take out the <Ref id=Server> from the binding of your jndi
resource, then look it up with:
ctx = new javax.naming.InitialContext();
String configArg = (String) ctx.lookup("jdbc/myDS");
