with regard to your first question: my understanding is that you’ll need sca-contribution.xml when you have interdependent contributions. For example, when contribution A has a component which you want to include in a composite that sits in contribution B (using implementation.composite), you’ll need to export/import the namespace of A.
Also, the SDo-databinding will pick up type definitions from XSD-files only if these files are mentioned in sca-contribution.xml. n Sebastian From: ESSOUSSI Mohamed Habib [mailto:[email protected]] Sent: Monday, January 16, 2012 9:17 AM To: [email protected] Subject: Is META-INF/sca-contribution.xml needed when running Tuscany standalone without SCA Domain Good day, I am beginner in Tuscany SCA, I would like to ask you some questions about its architecture. 1. I am wondering if the file META-INF/sca-contribution.xml is compulsory when running Tuscany standalone without SCA Domain? Because in several defintions of the term "contribution", it's mentionned that these SCA artifacts are only needed for the SCA Domain. 2. In my applications, I don't use neither SCA Domain nor sca-contribution.xml and that works fine withtout (my contributions are absolutely independants) ! What's the usefulness of an SCA Domain then ? why would we need a SCA Domain ? 3. Can I host distrubuted contributions,composites etc... within a same SCA Domain? or they should all be local ? if local, then again, what would be the usefulness? :) Thanks a lot Yours -- ESSOUSSI Mohamed Habib TELECOM SudParis IDS Scheer Consulting GmbH Geschäftsführer/Managing Directors: Kamyar Niroumand, Ivo Totev Sitz/Registered office: Altenkesseler Straße 17, 66115 Saarbrücken, Germany - Registergericht/Commercial register: Saarbrücken HRB 19681 http://www.softwareag.com
