Hi Vijai,

This may occur when the attribute 'subscriber_id' does not exist on the session. It will be better to ensure that subscriber_id always exists on session before trying to use it.

vijai sahu,
Welcome to JavaRanch!

In an effort to help you get the most from our forums, we've compiled a

In particular please see:

"can any body help" tells us nothing about the nature of your app.
Many people won't even open a thread if the subject line doesn't describe what's in it.
