EJB client cannot Load Remote EJB

[pushpak1981]

Hi,

We have deployed stateless EJB3 in JBoss 5.0 AS. We have written an Junit class which Does an JNDI Lookup for the EJB. But it is not able to load the remote EJB Object. We are getting following Error.

java.lang.NullPointerException

Any help would be highly appreciated.

Thanks.

For Doing an Lookup we are using the following code:

Properties p = new Properties();
p.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
p.put("java.naming.provider.url","jnp://localhost:1099/");
p.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");

InitialContext ctx = new InitialContext(p);
IAbc ref = (IAbc)ctx.lookup("TransactionBean/remote");

ref.addTransaction(persistenceObject);

We are doing an persistence into Database using JPA.
