I would like to use Crystal Reports with Weblogic Workshop. My requirements include ad-hoc querying and canned reports. Can the JRC SDK satisfy these requirements alone or do I have to use it with the RAS? In your opinion, what do you think of the SDK's robustness and ease of use? Also, is the JRC SDK just a downloadable jar file or do I have to download say, the Enteprise Edition of CR?
