Hi Alfredo, Sorry we could not follow up, I am at a conference and only paying fractured attention. Can you please login to Airavata Instant Messenger (http://s.apache.org/hipchat) and lets interactively get this quickly. For now, please see the walk through below:

Yes thats exactly what you will need to do. Three string inputs with three InputDataObjectType objects. I would suggest you play around with this on a test portal which will let you walk through this - http://test-drive.airavata.org/pga/public/ (please ask for a test user name password on hip chat). > > > b) Assuming a simple case where "output" is composed by a string > > > indicating the result of the processing, how is this "output" associated > > > to the output of the airavata interface which I'm creating? it's always > > > what happens comes with the stout of the system or there is a specific > > > procedure to follow into MyApp or before create the registration script? Output are little tricker to automate. Please see this thread for details - http://airavata.markmail.org/thread/hd7azhp7w7o7eqyq The easier way is, if you application (or a wrapper) can print OUTPUT_NAME_USED_IN_REGISTRATION=value, then airavata can pick it up. There used to be a way to just tell get me all standard out.

In the current version only simple types are supported. But this is a good use case, you can please create a JIRA issue requesting this new feature, and we will look into it. Again please login to the IM and ask any questions you may have. Thanks for your persistence and patience. You are not at all harassing, you are being a great contributor to Airavata by means of all these questions. We very much like it and would encourage you to continue to do so.
