I am interested this period to reporting tool, since a month ago I am searching the best tool to generate easily and perfectly a good report.
After Business Object and Cristal Report, JfreeChart, then Birt, finally I found jasper Report and his report design tool iRreport.
I choose jasper Report for three reasons. First, Jasper report is easily integrated with Spring framework, in fact, Spring offer a view class to integrate jasper report in your web application.Second, Jasper report use JrfeeCchart to generate some chat. Third, iReport is very good tool, easy to use, rich with his variety of chart. And finally, because with Jasper Report I can generate cross tabs.
