Answer 1

rs2xml.jar doesn't contain the needed java class. The most probably reason is that it was built incorrectly.

As you may see it contains 'src.net.proteanit.sql' which is empty.

So to fix the problem the jar should be rebuilt

1. The package should not include 'src' prefix
2. The DbUtils class should be truly included into it.
