Yeah - for us this was a holiday weekend, so no work on Monday.
What you are looking for is indeed going to be an awful lot of work. You will be using the In Proc RAS Report Creation APIs. And there is nothing simple there.
Start with sample apps documented here:
Business Objects / BI Unmanaged Java RAS SDK Sample Applications
Also see the links to sample apps in this doc:
SAP Crystal Reports, version for Eclipse Sample Applications
Unfortunately, I do not have any "here is how you do this in 10 easy steps" documentation.
More genaral info on CR for Eclipse:
Overview (Java Reporting Component API Reference)
Search box is in the top right corner and a few searches may be of help. Use simple strings like 'crystal java parameter'.
