How to retrieve a DataSource from JBoss via JNDI

What I am trying to do is to retrieve a DataSource from a locally running JBoss (EAP 5.1) per JNDI. It works fine inside a deployed DAO, but I seem to misunderstand something as when I am trying to get the DataSource in a test case, I keep getting a javax.naming.NoInitialContextException when trying

        Properties env = new Properties();
        env.put(Context.PROVIDER_URL, "jnp://lo开发者_如何学JAVAcalhost:1099");

        final InitialContext ic = new InitialContext(env);
        ds = (DataSource) ic.lookup(DATASOURCE_NAME);  

If i add

        env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");

I get a ClassNotFoundException for the org.jnp.interfaces.NamingContextFactory

Being new to JNDI and JBoss, I'm stuck at that point. Searching the web just adds to my confusion as all I find are scattered pieces of info that I try to apply by trial-and-error with no real progress.

Thank you

What functionality is it that you are testing? Is it the retrieval of a DataSource or some actual database code? If the latter, then I would suggest not using JNDI at all and using a local DataSource implementation.

This thread shows how to use Commons DBCP to set up local DataSources.

If you really need the JNDI aspect, this example shows how to populate an InitialContext with a minimum of values to get a DataSource back. You can probably use the same Commons DBCP config as above to configure the DataSource(s) that you need.
