Jasper Reports

I've been trying to work (again) with the Jasper Reports suite of tools (Jasper Reports Server, JasperSoft Studio).  There's a Community (free) edition, and a variety of non-free commercial editions.

It's getting incredibly frustrating, because for the most part the documentation covers the commercial editions, with only a short disclaimer at the beginning that some of the features described may not be implemented in the Community version.

I find I'm repeatedly being led down the garden path towards a solution to the particular problem I'm trying to solve, only to discover that the feature being described is not available in Community.
