JBoss InitialContext problem

[Haun, Patrick]

Hi,

I'm using JBoss 4.2.2.GA. I'm trying to use a datasource from the inside
of my Application. Therefore I try to get the EntityManager via a JNDI
lookup.

A JSP file containig this code snippet:

                InitialContext ctx = new InitialContext();
      DatabaseMetaData dm = null;
      DataSource ds = (DataSource)
      ctx.lookup("java:/DerbyDS");

works completly.

But inside my OSGi Application I get the following errors:

1.: using this code snippet
          Context ctx = new InitialContext();
        ctx.lookup("java:/DerbyDS");
               
                leads to
                09:59:34,750 ERROR [STDERR]
javax.naming.CommunicationException: Receive timed out [Root exception
is java.net.SocketTimeoutException: Receive timed out]
               


2.: using this code snippet
       
           final Properties env = new Properties();
         env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
         env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
         env.put(Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces");
         final Context initialContext = new InitialContext(env);
         initialContext.lookup("java:/DerbyDS");

                leads to:
                09:59:29,508 ERROR [STDERR] DerbyDS not bound


This is my underlying problem. If the JNDI lookups do work properly I
want to get the Entity Manager this way.
