7. Flash Remoting and Java > 7.7. Invoking Service Methods

Invoking Service Methods

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.
