When using JFreereport in Web Application, people only can generate the report in applet format, or just directly generate as pdf, excel.
I used to use another report tool(commercial), it will generate the report as a picture on web page, and has toolbar on top of the page. User can click the hyperlinke"Export as pdf", "Export as excel" on the toolbar, and the pdf or excel file can be generated.
If JFR can do this, I think more people will enjoy it.
