Haig,
You need to use a different Statement object for the second query.
According to the jdbc spec you can have only one result set open at a
time for a given statement. So when in the code you create rs2 from
stmt you are causing rs to automatically be closed. Then when the next
iteration of the look is executed rs.next() will fail.
