Well, what's wrong with this post. Let's count the ways:

1. You use a bad title (you can use Java to search a MySQL DB, but you can't use a MySQL DB to search Java).

2. You dump a bunch of unformatted into the post (because of a very poor attempt at using code tags).

3. You provide no description, what-so-ever of what your actual problem is.

4. You say "please see attachment" with some funky symbols after it, but didn't attach anything.

5. And I haven't even started to look at the code, either (and won't).
