    NullPointer exception!

      In my latest application I am using 3 tier architecture.

      1.Glassfish(V2) as the app server
      2. frontend is a web application (JSF)
      3. enterprisedb database
      also using ejb as business components.

      In my application i have written a stored procedure to calculate the interest of all existing customers. Also i used a return parameter inside the procedure. Procedure is working well.
      But when i am calling the stored procedure from my ejb, some time is gives 'NullPointer Exception' but the procedure is excuted and the interest calulated successfully.

      Here i am using connetion pool to connct to the database.

      It is never occour all the time. but sometime it will occour.

      Can any one help me to solve above problem?

      thank you....
