wsad 5 - initial context from client module

[Jeanne Boyarsky]

I am trying to access the initial context from a client module in WSAD 5.1. I get an initial context, but when I try to get the datasource from it, I get:
NoClassDefFoundError
Invalid Implementation Key, com.ibm.ws.transaction.TXCurrent
I also get this error if I call an access bean from the client. Any ideas of where this file is or what else could be causing the error?
My code is:

Hashtable parms = new Hashtable();
parms.put(
Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.ejs.ns.jndi.CNInitialContextFactory");
parms.put(Context.PROVIDER_URL, "iiop:///");
Context ctx = new InitialContext(parms);
DataSource dataSource =
(DataSource) ctx.lookup("jdbc/MyDataSource");

Also, are there any tricks about running from the client in 5.1. Like in 4.0, we had to change the JRE for the client project.

There is a trick or two. It's documented in the InfoCenter. Look for "Configuring data access for application clients" or "Application Client Resource Configuration Tool" for the reference.
Or alternatively, look in the EJB client chapter of my book.

The main problem was that I was running as a junit test and not as a client program. Thanks for the help references.
