Rafael,  
I and some other sad people I’ve met tried to make this a reality and  
wasted many weeks working through the gauntlet of half truths.  
It is totally a bogus lie that this can be done.

David,thanks for your answer.  
My situation is the following:I have a table with various 1-n  
relationships,and I need to show all of this in a single report,is there  
some way to do this?

I’ve created a Java class(executed through my Jruby app) that  
successfully generates the “parent” report,but I´m not figuring it out  
how to show its “childrens”.

Regards,  
Rafael R.

This really sounds like a JasperReports question and not really  
anything with Rails. To do a parent/child report in JR you need to  
have a sub-report for the children that the render process will  
populate with your collection of children. If you’re using iReport to  
build your report it’s pretty straight forward.

Rafael,  
Sure. I use Ruport which is really cool and you’ll find many examples  
of this if you Google.  
I’d very much like to share information on JRuby if you’d contact me.

It is cumbersome to render a subreport from Rails.So I just wondered if  
someone has already come up with another solution
