Trouble exporting an application with the Eclipse Product Export Wizard (Windows) [message #689886] Tue, 28 June 2011 10:42 Go to next message

Hello,

I am having trouble exporting an application with the Eclipse Product Export Wizard. I defined my own IApplication (de.emsw.gosa.product.etisch.ETischApplication) to be started. This Application uses a Service (de.emsw.gosa.klassik.service.IGosaKlassikService) which is defined with DS in another bundle. This works fine in the PDE but when I export the application and start the EXE (Winows XP) I get the following exception written to the log:

java.lang.NoClassDefFoundError: de/emsw/gosa/klassik/service/IGosaKlassikService

I am wondering why I get an NoClassDefFoundError since the service-bundle is correctly required in the manifest.mf of the the app-bundle and the interface (IGosaKlassikService) is provided as an exported package in the service-bundle.

Any help is greatly appreciated.

Regards
Christoph

Hi,

I am still working on the problem. If I try to start the problem-bundle automatically, I get a little bit deeper into the problem. The error I get written to the log now looks like this:

Which I still don't understand, because the Activator is straight forward:

package de.emsw.gosa.klassik.service.impl;

import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class GosaKlassikPlugin implements BundleActivator {
	public static final String PLUGIN_ID = "de.emsw.gosa.klassik.service";
	
	private static BundleContext bundleContext;
	
	public static BundleContext getContext() {
		return bundleContext;
	}
	
	@Override
	public void start(BundleContext context) throws Exception {
		GosaKlassikPlugin.bundleContext = context;
	}

	@Override
	public void stop(BundleContext context) throws Exception {
		GosaKlassikPlugin.bundleContext = null;
	}
	
}


Any suggestions where I could look next?

Thanks,
Christoph

Hi,

in case somebody is wondering: It was a problem with the build.properties. it was missing the "." in bin.includes so the class file of the activator was not put into the plugin.

Regards,
Christoph
