Strategy to get the resources by the given classloader. to take care of WebSphere's odditiy of resource loading.

参数:

loader - the classloader

packageName - the packagename for the package to load

返回:

URL's for the given package

抛出:

java.io.IOException - is thrown by the classloader

                                 throws java.io.IOException

Finds matching classes within a jar files that contains a folder structure matching the package structure. If the File is not a JarFile or does not exist a warn will be logged, but no error will be raised.

Any nested JAR files found inside this JAR will be assumed to also be on the classpath and will be recursively examined for classes in `parentPackage`.

参数:

parentPackage - the parent package under which classes must be in order to be considered

parentFileStream - the inputstream of the jar file to be examined for classes

loader - a classloader which can load classes contained within the JAR file

parentFileName - a unique name for the parentFileStream, to be used for caching. This is the URL of the parentFileStream, if it comes from a URL, or a composite ID if we are currently examining a nested JAR.

grandparentFileName - grandparentFileName

抛出:

java.io.IOException - IOException
