Solved. I really stupidly forgot an rs.next() :-(((.

Well, that might be true for query and rs and I'll change that, but
in my opinion
public class ServletSQLClass
{
private Connection con;
private Statement stmt;
...
con = DriverManager.getConnection(url,user,passwd);
stmt = con.createStatement();
...
}
con and stmt have to be class scope to hold the connection to the
database and don't have to reopen over and over. Or did I understand
something wrong?
Kind regards
Andreas.
