Hi! Forum The English it's not my first language so I gonna be my best try. Sorry! My question it's about sub reports 1. Have a Master report 2. Have a sub reports 3. Have my java class and set into my variable one data Ok, here the trouble..... Now, When I execute my program java the jasperview shows only one part of my report show(the data that I choose), and my subreport don't show anything... My question here is, have some way to put in my subreports the principal parameter from my master report? Note: When I've set a parameter inside in my program java, in my master and subreport WORKS.
