Val,
you need to specify the class-loader that has access to the resources in
your plug-in (see
org.eclipse.rwt.resources.IResourceManager#setContextLoader) .
Cheers,

Val,
you need to set the ResourceManagers' context-classloader just before
you register the resource and reset it to its previous value afterwards.
If there is a class that resides in the same package as the resource to
load, its classloader would be a good candidate. Usually, any class that
resides in the same bundle should do (special cases left aside, they all
share the same classloader).
Typical code could look like this:
IResourceManager manager = ResourceManager.getInstance();
ClassLoader buffer = manager.getContextLoader();
manager.setContextLoader( <YourClass>.class.getClassLoader() );
try {
// register resource
} finally {
manager.setContextLoader( buffer );
}
