How to unload a dll which gets loaded by System.load(path to dll)

问题

Is there any way to unload a DLL which gets loaded in the application using System.load() API call.

回答1:

You have to use a separate ClassLoader to load the dll. The dll is only bound to the ClassLoader it was loaded with. When the ClassLoader isn't used anymore (means no references to the ClassLoader exist), the garbage collector will free your ClassLoader and unload your dll.
