Exception when starting java_first_jaxws example

Hi,

I'm trying to deploy and test the "Code first development" example as described in the Development Guide 5.0_b (chapter 3. Web Services). I've successfully installed the bundle but when I try to start it, I'm getting the following error:

Do you have an idea how to fix this?

Martin,
your issue seems to be pretty similar to Export demo to deploy folder of container,karaf generated errors!. Which jave jre/jdk are you exactly using?

Hi Martin,
I had a second look on your issue. Just forget my first posting, it is not related to the JRE / JDK version you used. I could reproduce the problem when using TESB 5.1.0 (With 5.0.2 it works fine). With CXF-2.6.0, the version we integrate with 5.1.0, the one big bundle used before was split into several smaller bundles. This seems to cause problems in our sample. Unfortunately I don't have a solution or workaround yet, but I will keep you updated.

Regards,
Zsolt

The java_first_jaxws archetype wasn't updated for CXF 2.6.0 (oversight on our part) -- it was updated last week and should be fine for the upcoming CXF 2.6.1 (not yet released though sad )  This guide will also probably need updates (I'm checking it now.)

In the meantime, this tutorial can teach you Java-first development:  http://www.jroller.com/gmazza/entry/jav … eb_service  (although we'd always rather everyone start learning with WSDL-first   smile

Martin,
a possible workaround is to use JAX-WS as frontend in the Activator class instead of the Simple frontent as documented in the guide. The activator class would then look like this:

package demo.hw.server;

import javax.xml.ws.Endpoint;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class Activator implements BundleActivator {
	private Server server;

	public void start(BundleContext arg0) throws Exception {
		try {
			HelloWorldImpl implementor = new HelloWorldImpl();
	        String address = "http://localhost:9000/helloWorld";
	        Endpoint.publish(address, implementor);
			System.out.println("Server is started...");
		} catch (Exception e) {
			e.printStackTrace();
			throw e;
		}
	}

	public void stop(BundleContext arg0) throws Exception {
		try {
			server.stop();
		} catch (Exception e) {
			e.printStackTrace();
			throw e;
		}
	}
}

We should change the example to use JAX-WS ayway.

BTW, I logged your issue in TESB and in CXF

Hi all,

thank you very much for your fast and comprehensive help! I've successfully deployed the examples from Glen's blog (java-first and wsdl-first ;-)) as well as the original example from the developer guide using the JAX-WS frontend in the Activator class as suggested by Zsolt.

Kind regards
Martin
