u can create a new DLL including jni.h, its functions would call to
no-sources-DLL functions (like a wrapper), thus u could access the DLL from
Java...
Hope it helps...

I've checked that. The documentation says:
<cite>
The JNI allows Java code that runs within a Java Virtual Machine (VM) to
operate with applications and libraries written in other languages, such as
C, C++, and assembly. In addition, the Invocation API allows you to embed
the Java Virtual Machine into your native applications.
</cite>
So it is correct, you can use _some_ of the DLLs, if written in C++. But
after checking the tutorial it looks like you have to compile this DLLs with
the header include:
#include <jni.h>
If you can't compile them because you haven't the sources, it won't work, I
assume.
ciao!
