how would I resove this?
If you would have posted the StackTrace and the code in your first post- You would surely have got the reason for the exception- with so many people willing to help you. Its always good to post the working code( a small prototype where you can capture the problem). What happens is sometimes the exception name might make it to seem obivous but with out the stacktrace we cannot identify at which line its being thrown and with out the code we cannot tell you why that exception is being thrown at that line.
