                             throws IOException

IOException

getResources

protected Enumeration<URL> getResources(ClassLoader loader,

                                 throws IOException

Strategy to get the resources by the given classloader.

Notice that in WebSphere platforms there is a WebSpherePackageScanClassResolver to take care of WebSphere's oddity of resource loading.

Parameters:

loader - the classloader

packageName - the packagename for the package to load

Returns:

URL's for the given package

Throws:

IOException - is thrown by the classloader
