Spring's jasper report integration is really focussed on the web tier.
I decided to write my own jasper integration, to also have support for some sort of template. But it's not cleaned up yet, so not ready to be added to spring-richclient sandbox (if it fits there anyway).

ge0ffrey,
We just wrote a templating front end to Jasper ourselves. I'm just curious how you approached it?

Hi all,

So , in this case, if i need to write a Jasper report, i need to write my own wrapper class directly from jasper and not on spring, is it something meaning like that ? If so, how come spring integrate with the view of jasper? Is it any tricks behind ?

Some more , i found that the JasperReportMultiView i am unable to integrate, mean while I create the pdf,csv,html seperately is doesnt issue.However, while i create the form by user choice , I use of the jasperreportmultiview then it come out some of the errors. It make me confuse, should have any tutorial on this? Thanks for advice.

Andy, here's my trick how I did the template design. How does it differ from your template, could we merge it and commit it to spring RCP?
