Multiple Prepared Statements in JSP

Aug 22nd, 2009

Hello all, I've been working on a project where I wish to retrieve two sets of information from a MySQL database using two prepared statements. When I try to do this I get a blank screen, but the first query is successfull executed. Any suggestion would be greatly appreciated.

Thanks.

Not normal behaviour. If adatapost will not solve it please provide code sample of you using.
