WebSphere 5.1 and JTA

[Paul Sturrock]

We've got a TimerTask which is kicked off by a ServletContextListener when the web app starts. In this task we lookup a user transaction (as directed by the InfoCentrer docs) like this:

InitialContext initialCtx = new InitialContext();
UserTransaction tx = (UserTransaction) initialCtx.lookup("java:comp/UserTransaction");

But always get a NameNotFoundException. We've tried a bunch of different patterns for the lookup string but no luck. dumpNameSpace.bat shows a usertransaction binding in JNDI at (top)/nodes/localhost/servers/server1/jta/usertransaction.

Anyone done this before and can spot what might be going wrong?

I am having the exact same issue (TimerTask but attempting to get DB connection via JNDI). Did you ever find a solution to this issue?

[Judy Spengeman]

I am facing the same problem with a connection to a database using the Resource binding configured in the web.xml...

Please help me resolve...

You gotta tell the Context where to look, something like:

Hashtable properties = new Hashtable();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
properties.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext initialContext = new InitialContext(properties);

... then go your call

you probably need to set the resource reference correctly in your web app.
