Ok, I am being hit by this problem again, despite the temporary hack that
tries the old class loader in LoaderUtil if the current class loader does
not work. Furthermore, the missing resource is not an app resource any more.
I am not really familiar with how class loaders are being handled. Trying to
chase this down is probably going to take me more time than whoever may be
more familiar with class loader set up. I am trying to verify my latest
inner.composite sample, which was running previous to doing an update (which
in turn I did to be able to post the patch including this latest
inner.composite sample) and this is getting in the way.
Here's the actual exception I am getting:

And here's the contents of LoaderUtil.loadClass that includes the hack that
allowed me to make progress earlier:
public static Class<?> loadClass(String name, ClassLoader cl) throws
MissingResourceException {
final Thread thread = Thread.currentThread();
final ClassLoader oldCL = thread.getContextClassLoader();
try {
thread.setContextClassLoader(cl);
return Class.forName(name, true, cl);
} catch (ClassNotFoundException e) {
try { System.out.println("Trying old class loader");return
Class.forName(name, true, oldCL); }
catch(ClassNotFoundException e2) {System.out.println("Still not
found");}
throw new MissingResourceException(name, e);
} finally {
thread.setContextClassLoader(oldCL);
}
}

Subject: Re: Can't load implementation.composite
Ok, will try that.
Another question, any idea why a resource (a Java interface .class file)
would not be found? I get the exception:

And I do have a Source.class file in package innercomposite, as far as I
can tell. One guess I was trying to pursue was that the class loader may
be wrong for some reason. Does that ring any bells?
