                                         URISyntaxException

For all non-class elements of java classpath with path resourcePath, gets a Collection of resources with pattern resourcePattern

Parameters:

cl - the class loader to use

urlResolver - the url resolver needed to transform classpath URL to native java classpath library, in non classic environments such as OSGI
If unset null, no resolver is used

resourcePath - the parent path of resources in classpath

resourcePattern - the pattern that must match file names of resources

Returns:

the resources array in the order they are found

Throws:

IOException - if an error occurs during the resolution

URISyntaxException - if url is not well formatted
