JNI : Two native libraries with the same functions

[floca77]

Hello,

I have two versions of the same native library like "abc_v1.sl" and "abc_v2.sl" .
They have the same functions but they act differently.

I want to use both of them in parallel (each in its own thread) but only the functions of the first loaded library are being called.

Isn't there any possibility to load each native library in a different name space... maybe a different JVM?

Any help will be appriciated.
Thank you!

I don't think that's possible. If they have the same name then you are probably getting a name clash.

Well, different JVM implies different processes, so then anything is possible.

I believe that within one JVM, having different class loaders may allow you to load these libraries. The separate class loaders will keep them apart.

Can you give me an example on how to use class loaders in this situation ?

'Cause the native libraries are just loaded into memory using

System.load([I]<libraryName>[/I]);

and I don't have any possibility to keep them apart.

Thanks again!

Try using a URLClassLoader and then, in the class you've loaded try using System.load and see which ClassLoader gets used. No guarantees, but it's worth a try.
