Ravi,
 
In order to help you; we will require more information;
 
The absolute best is a small snippet of code which reproduces the problem; but at the very least the code leading up to the rs.next, and following it
 
What version of postgres are you running? What version of the jdbc driver are you running, etc?
 
Dave
