Answer 1

You could check the order of directories in the classpath. I once had two versions of a jar file: one in the working directory and another in the Java Extensions directory. The order of the classpath was: check eclipse extensions directory first, then working directory second. Once it found a version of the jar in the extensions directory, it didn't keep looking for the one I was specifying in the working directory. Order matters in the classpath.
