Subject Help: Eclipse RCP as remote OpenEJB client
Date Thu, 30 Oct 2008 12:43:45 GMT

I have an eclipse RCP application based on eclipse 3.4. I want it to connect
remotely to and openejb server. I have openejb-client-3.0.jar on the
classpath. My connection and lookup code is as follows:

try {
		Properties properties = new Properties();
	        properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.RemoteInitialContextFactory");
	        InitialContext ctx = new InitialContext(properties);
	        Server s = (Server) ctx.lookup(Server.class.getName()+"Remote");
		} catch (Exception e) {
			e.printStackTrace();
		}

This piece of code bombs out at the line : Server s = (Server)
ctx.lookup(Server.class.getName()+"Remote");
with the following stack trace:
