Java native library System.loadLibrary fails with UnsatisfiedLinkError

Question

I'm trying to use a native C++ library in Java.

When I'm loading it with

System.loadLibrary(filename);

I get the error:

java.lang.UnsatisfiedLinkError: Directory separator should not appear in library name: C:\HelloWorld.dll

Any ideas how I can solve this?

Answer 1

Just use:

System.loadLibrary("HelloWorld"); // without c:\ and without ".dll" extension

Also, make sure HelloWorld.dll is available on your library path.

Answer 2

loadLibrary needs the filename without the path and the extension.

If you wanna use the full path, you can try the System.load() method.

See java.lang.System API.
