If you have a service that a consumer is going to use then the consumer needs to understand the interface of the service. Including the exceptions that can be thrown. In SCA we support several different interface languages including inteface.java and interface.wsdl. If you provide the consumer with a Java interface file, and the consumer is implemented in Java, then they could use this straight off. If WSDL is provided then the consumer will need to generate interfaces appropriate for the environment in which they operate. Which eve route is taken the interface should describe the exceptions that the service is able to return and hence the consumer should be able to take the appropriate action. Have you spotted some deficiencies in Tuscany in this area? Regards Simon
