Is it possible to Execute a report using Crystal Reports Viewer

Hi,

A report has been designed using Crystal Reports 2008.

The designed report is published on RAS and uses DSN to an SQLServer to execute. The executed report output file (.rpt)

is stored at a location on the disk.

I need to display the same report using Crystal Reports viewer (deployed as a WAR file on JBoss). However, when a user changes the report parameters and applies them, the report fails with the error

'JRCCommunicationAdapter - detected an exception: Error finding JNDI name (EKT_UAT)'

My questions are:

1. Can a report, designed to use DSN, be re-executed using JDBC parameters?

2. If so, how? How do I get round the JNDI name problem.

cheers,

Gaurav
