Crystal information is needed before this report can be processed

hello

I have doing a program in jsp to open a report rpt.

i using session

( thanks shawn

1. After you run through the first time, save the report / reportsource in session and just retrieve that on each subsequent postback. This is a common technique.

2. Save the values that you retrieved from the request object into something that persists between postbacks - such as session or a cookie.

it's ok)

when active viewer is open i's ok export ok , tbnext ok , tbfirst on ,

printer ok

but i have 2 little problem
