Hi arun, this is exactly what my Footprint Project do :) the distribution of certificates (for attendees and/or speakers). The project is being used by several JUGs and courses and nowadays I am trying to finish a RESTful web-service based on Glassfish and Jersey to make it even simpler to use. And I need a GUI - that http client I tried to talk with you during JavaOne :) Here it is the Certificate generator project: https://footprint.dev.java.net/ Here it is the REST contract: http://fgaucho.dyndns.org:8080/footprint-service/wadl Here it is a presentation about footprint: https://footprint.dev.java.net/files/documents/7027/121112/footprint.pdf * I hope we can still finish the footprint service and also code a nice GUI to the Java community.... * FISL, btw, is exceptionally well organized and it deserves a kudo or two .. :)
