Hi all, unfortunateley I am not able to solve the following problem: I have a main-report that fetches data through jdbc from a postgres database- standalone working (=ireport preview). I want to include a subreport- also standalone working. This subreport has almost only static data, labels, text and should be an extra page as a fax answer for our clients. The few relevant data I want to display dynamically should be provided using (input) parameter. If I put them together I run into the java heap space error... Error.log is attached as are the jrxml report files. Any help would be appreciated! thanks, thomas
