Problem Embedding (Viewing) Crystal Reports in a JSP Page
Hi All,
I am trying to view a Crystal Report (CR10) in a JSP page using Web Logic and Crystal SDK but I keep getting the error below. I have been able to get the List of Reports on the Server but cannot view them. I am using is CrystalReportViewer class.
ERROR:

An error occurred at the server: The Page Server session you are using to connect is in the process of being shut down. Please retry.
