I'm trying to run a report on jasper server 4.2.1 from java using rest webservice (HttpComponents) and I get: "Invalid resource descriptor" I've attached the code trying to do the put method to get the uuid. Is there something I'm ommiting? From Web Services guide - there's stuff about a "resource descriptor of type reportUnit" that must be included but I can't make sense of what that means. Does anyone know where I'm going wrong? Also is this the best way to run a pdf report from java using REST? Code: Post Edited by jazzman at 01/09/2012 20:16
