Same method name in different DLLs

Question

I have two C++ files, "File1.dll" and "File2.dll". Both contain the implementation of a native method. The signature (name, arguments and return types) for each native method are identical, however, the code itself for each method is very different. For simplicity, assume both method are called runmethod(...).
Firstly I want to run the native method runmethod(...) contained in "File1.dll", and then a few lines of code later I want to run native method runmethod(...) in "File2.dll" .
I do a System.loadLibrary("File1.dll") and call runmethod(...) with no problems. However, my problem starts when I then do a System.loadLibrary("File2.dll") and call runmethod(...) again. Unfortunately, this runs runmethod(...) in "File1.dll"
Is there any way I can, when invoking a native method, force it to use a particular dll in cases where there is a name clash.
(Changing the C++ source code is not an option BTW. Unloading the first DLL would be ideal but I understand from looking at other threads this cannot be done. )
Many thanks in advance
David.

Answer 1

You have to dynamically load the second dll and create the method pointers yourself. This is somewhat akin to reflection in java. Note that doing this means that all of the methods have to be called that way (although you might be able to load it twice.)
