I have installed jdk 1.7, ant 1.9.9 and jbpm 6.3.0. It installed properly. I have created simple workflow example of hello world using start, script and end events. In the script task I have just written to print hello world and then I saved, created sessions and base, marked base as default then I saved changes and did build & deploy. project deployed properly. but unable to see the my process (in process management->process definition).
