So far I have learned creating simple reports,passing parameters,hyperlinks,subreports..but looking for more advanced things like expandable/collapsible reports and want to know the actual power of Jasperreports. Please help me with any guidance..I will soon be posting any issues that I will face in future.And will try to participate in other's posts where I will feel that I can help somebody.
