Is it legal to use Jasper Server commercially?

[MichaelQ]

Since there seem to be a number of people here using Jasper reports, I was wondering if it is legal to use Jasper server in commercial apps?

I believe the licence for Jasper Studio is OK for anyone to use anyhow, but Jasper Server has an AGPL licence which seems more restrictive than GPL. From my readings, any app that is sold incorporating Japser Server has to make it's own code available as open source also. I get the impression that to run a Jasper server and serve reports commercially is not allowed. (They offer their own commercial web service for that).

This begs the question of why would they bother making Jasper free and open-source unless it is just for hobby use?
Can Jasper reports be generated without use of the server?

Does anyone have any comments about this? Or have I misunderstood?

Many thanks,
Michael
