Hi All,

Just to add more to the above exception i found that I am creating a prepared statement from a connection but i am not execution the prepared statement since it is not satisfying some condition so when i am closing the prepared statement it is trhowing a null pointer exception.

My environment is WAS 6.1.0.29 , DB 10g, jdbc driver version 9.0.2
