I have written a program that I put into C++ for speed reasons. I now want to use the JNI to
a) Get familiar with the JNI
b) To merge a Java GUI and speedy code together.
I've read that if you use the JNI then you cannot run your program everywhere. But I thought about programs written in C/C++ that do run everywhere, with respect to say the OS.
So isn't it possible to still have that via the JNI?

So, you measured the speed of a Java prototype and a C++ prototype and found the Java version to be significantly slower?
Or you just assumed it would be?

You may be able to use the same C/C++ source code, depending on what it's doing, but you'll at least have to recompile the native code. A Windows DLL can't be used on a Linux box.
