I don't have first-hand experience with JEE6 namespaces, but default Cayenne
config loading is based on ClassLoader URLs. You didn't mention what version of
Cayenne you are using, but assuming 3.1, ClassLoaderResourceLocator.class is
responsible for XML file location. It does the following to find the right
ClassLoader:
protected ClassLoader getClassLoader() {
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if (loader == null) {
loader = getClass().getClassLoader();
}
if (loader == null) {
loader = ClassLoader.getSystemClassLoader();
}
if (loader == null) {
throw new IllegalStateException(
"Can't detect ClassLoader to use for resouyrce location");
}
return loader;
}
What this means is that XML files must be accessible from the ClassLoader that
loads Cayenne's own classes. BTW, you didn't post the error you are getting
either. Maybe there are some clues. And finally - if the standard
ResourceLocator above doesn't work, you can define your own.
Sorry if this answer is too abstract. I guess I'll need to experiment with
namespaces to better understand class loading patterns involved.
