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.
