Re: Problem with MyEclipse+JDBC Driver

Also, check for libraries that you're referencing. You might be having the
same libraries with different versions (libx-1.0 and libx-1.1) lying around
your build path.

Specifically, you get this when you compile for a platform newer than you are

try to run on 1.4. You'll get the bad version # exception.
