n00b RCP deployment problem [message #463808]

Hi everyone,

I'm running into a deployment-related exception when I use the export
wizard on my Eclipse RCP project's .product and launch the resulting win32
executable. For now the product is based on plug-ins, just to keep it
simple. I have my project's plug-in and clicked the "add required
plug-ins" button. After I run the export wizard, I can see my
Activator.class in my plug-in's jar file under the <deployment>/plugins
directory.

Running the project from within Eclipse (debug and release) are working
fine; it's running from the launcher that's failing. Any ideas what I'm
doing wrong here?

If it'll help, here's the code for my activator class. It's pretty much
straight modified from the Eclipse RCP book:

package <snip>;

import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.plugin.AbstractUIPlugin;
import org.osgi.framework.BundleContext;

/**
* The activator class controls the plug-in life cycle
*/
public class Activator extends AbstractUIPlugin {

// The plug-in ID
public static final String PLUGIN_ID = "<snip>";

// The shared instance
private static Activator plugin;

/**
* The constructor
*/
public Activator() {
plugin = this;
}

/*
* (non-Javadoc)
* @see
org.eclipse.ui.plugin.AbstractUIPlugin#start(org.osgi.framew ork.BundleContext)
*/
public void start(BundleContext context) throws Exception {
super.start(context);
}

/*
* (non-Javadoc)
* @see
org.eclipse.ui.plugin.AbstractUIPlugin#stop(org.osgi.framewo rk.BundleContext)
*/
public void stop(BundleContext context) throws Exception {
plugin = null;
super.stop(context);
}

/**
* Returns the shared instance
*
* @return the shared instance
*/
public static Activator getDefault() {
return plugin;
}

/**
* Returns an image descriptor for the image file at the given
* plug-in relative path
*
* @param path the path
* @return the image descriptor
*/
public static ImageDescriptor getImageDescriptor(String path) {
return imageDescriptorFromPlugin(PLUGIN_ID, path);
}
}

Hi everyone,

I managed to track it down - there was a problem in my build.properties
file that was placing my Activator.class file in the wrong path.

FYI - in case someone else runs into the same problem, I ended up fixing
it by going back to the bare-bones distribution in the RCP tutorial part 1
( http://www.eclipse.org/articles/Article-RCP-1/tutorial1.html), making
sure I could get that to deploy, then comparing the directories in the
plugin.xml, <x>.product and build.properties to see if there was anything
fishy.
