Method Detail

getResource

public static URL getResource(String resource,
                              ClassLoader classLoader)

This method will search for resource in different places. The search order is as follows:

1. Search for resource using the thread context class loader under Java2. This step is performed only if the skipTCL parameter is false.
2. If the above step fails, search for resource using the class loader that loaded this class (Loader).
3. Try one last time with ClassLoader.getSystemResource(resource), that is is using the system class loader in JDK 1.2 and virtual machine's built-in class loader in JDK 1.1.
