JNI Problem

[Marcelo]

I would like to know what happens here....
In one computer (terminal) the program executes as normal, but in
another computer (terminal with ssh connection) it doesnt work anymore.
The message that I have is:

The library that I use for the JNI program is called libPrompt.so,
the command line that I use to compile this shared library is:
g++ Prompt.c -Wno-deprecated -shared -fpic -o libPrompt.so

Can anybody help me?

Your JVM searched for "libPrompt.so", but didn't find it.
You can check where the JVM actually looks for *.so libraries by doing
System.out.println(System.getProperty("java.library.path");
somewhere in your code. You'll get a list of directories (separated by
":" on Linux/Unix, by ";" on Windows). You have to put your *.so library
into one of the directories given there.
