Service endpoint interface
About this task
For every port type defined in the original WSDL contract, you can generate a corresponding service endpoint interface in Java. A service endpoint interface is the Java mapping of a WSDL port type. Each operation defined in the original WSDL port type maps to a corresponding method in the service endpoint interface. The operation's parameters are mapped as follows:
Procedure
- The input parameters are mapped to method arguments.
- The first output parameter is mapped to a return value.
- If there is more than one output parameter, the second and subsequent output parameters map to method arguments (moreover, the values of these arguments must be passed using Holder types).
Results
The next example shows the Greeter service endpoint interface, which is generated from the Greeter port type defined in the WSDL above. For simplicity, this example omits the standard JAXB and JAX-WS annotations.
