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

when i use tb_last and the treewiev i have an error

information is needed before this report can be processed

When you call the refresh method - it removes any database or report parameters you have set on the report and removes any saved data. So calling the refresh method should only be done if you will be passing in the database and report parameters afterwards.

I am having the similar problem.

My application is built in C# using Crystal Report XI SDK to connect to CRS 2008.

I try to follow your instructions but not success.

Could you give me more advise?
