Hi, The sca-contribution.xml uses a wrong qname for the composite. It should be: <contribution xmlns="http://www.osoa.org/xmlns/sca/1.0"; xmlns:ptool="http://eclipse.org/PlanningToolSCA/src/Task";> <deployable composite="ptool:Task"/> </contribution>Thanks, Raymond

The files .composite defined in the samples don't use wires, since I understand when you don't use wires is because you are using bindings for communicating the components inside a composite. ¿Is that right? ¿Is there any restriction for using wires when you run a contribution in Tomcat for example? 2. ¿Is POJO the standard comunication mechanism in the tuscany implementation when you use wires between components inside a Composite? 3. ¿Is there any example of many SCA Domains deployed as webapps in Tomcat that use ws bindings (located as a service of the composite, when this service is related trough a promotion of a component inside the composite) that are communicating between them trough those bindings? Your help will be apreciatted
