Once the gateway has successfully located the service identified by the Flash client, it tries to invoke the service method called by the client. The gateway must first get a reference to an instance of the service. It uses introspection to locate the service method and then call it.

For each service type, the gateway uses a different technique to get a reference to an instance of the service. Regardless of the service type, once the gateway has a reference to the service it invokes the service method in the same manner. It looks for a method that has the same case-insensitive name and parameters that match the converted parameters from ActionScript. If it can not find a matching service method, the gateway throws a java.lang.Exception with the message “Service [service name] does not have a method [method name] that matches the name and parameters provided.” Refer to Section 7.5.1 earlier in this chapter for an example of how to remedy this error.
