Hi, there, Recently I have made an open source portlet called "JasperRocks" which is compatible with Apache Jetspeed, Apache Pluto, eXo platform, JBoss GateIn and Liferay and uPortal. http://code.google.com/p/jasperrocks It is a RESTful thin client connecting with JasperReports Server 4.7.0 or after. I wish to add more features in future if I have spare time. Thank you for your attention. Ching
