I find wsprovide (located in the AS7 bin/ directory) to be pretty useful in this type of situation. Using bean-service as an example:
cd bean-service $AS_HOME/bin/wsprovide.sh -w --classpath target/classes org.switchyard.quickstarts.bean.service.OrderService
Run that and check the output directory for the generated WSDL and XSD. Let me know if that doesn't satisfy your need.
Thank you very much! This is a good entry point to generate the resources i need. After a little bit work by hand (correct namespaces and adding the service in the composite tag in the switchyard.xml), my service runs know and seems to work correctly.
