The tool isn't designed to run or work with JasperServer, its a JasperReports tool. To get it to work with JS it requires customizations that are not readily available. We may be posting more documentation about JS compatibility at some point in the future, but this is not currently planned. If we do so, we'll contact you. Until then you might post to the JS forums to see if others have modified the tool or if they have implemented similar functionality. - Mike
