Where are your forms located? Consoel first looks at its classpath to find them and then queries Guvnor for them. You may not have Guvnor running on localhost (which is the default option in console to look for a running guvnor instance at). If Guvnor is not running on localhost:8080 follow the docs: http://docs.jboss.org/jbpm/v5.3/userguide/ch.console.html#d0e4624 (Guvnor connectivity).
Hope this helps.
Thanks, I could able to bring it up the ftl files from cloud.
I have one more issue, I have generated taskform and image of the process at guvnor repository of the server, accessing the URL from local machine. I could able to start the process and see the taskform .ftl files. When I click the "Diagram", it shows "No diagram associated". I have uploaded the diagram with Processid-image.png. Same works fine in local environment.
