Posting just code without an explanation isn't going to get you much help. Just posting some text in the subject is not enough.

Please explain in detail what the problem is (beside using scriptlets in a modern JSP )

Well, I'm sure you know that I'm going to tell you that putting Java code into a JSP, especially database access, is a really bad practice that causes lots of problems, including ones like this.

My advice: move the Java code into Java classes, and use the JSTL and EL on the page rather than obsolete and discredited scriptlets.

Do you intentionally drop the first element of rs?

Ivan is correct.

The first rs.next() advances the rs pointer, so if only 1 result then the while rs.next() is false

leading to ... ?
