RCP Client for EJB


Hello

I am trying to build an EJB ECP Client, I already installed the OpenEJB OSGi
Bundle and add it to my RCP app dependencies but when i the application
reaches the JNDI lookup it fails.

My EJB Caller class is:

public class EjbCaller {


	static InitialContext ctx;
	static TestBeanRemote testBean;

	public static void init() throws Exception {
		Properties props = new Properties();
		System.out.println("init");
		props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
		ctx = new InitialContext(props);
		testBean = (TestBeanRemote)ctx.lookup("TestBeanRemote");
		System.out.println(testBean.toString());
	}
	public static String hello(String msg) throws Exception {

		init();
		return testBean.sayHello(msg);

	}

}

I am calling the hello method from an RCP Action as follows:
 EjbCaller.hello("rcp");

When I execute the test step by step it gives me first:

2010-02-18 09:09:41,064 ERROR [remote] "null OEJ/0.0" FAIL "Unexpected error

Remark: If i make a test with a standalone java client it works fine.

Thanks for help
