I *think* a file with a relative path is usually put into the directory from
which the JVM is started.
(that's what I've found so far - don't know if it's *always* true)
Well, anyway: "File" has a method "getAbsolutePath()" (or something like
that).
Just let the file tell you where it is :-)
File file2 = new java.io.File("states.gip");
System.out.println("I'm file2 and I am at " + file2.getAbsolutePath());
HTH - Good luck!
