WSIFPort interface
The port implements a factory method for the WSIFOperation interface.
For detailed information about the WSIFPort interface, see the generated API documentation that is supplied with WSIF (see the Apache WSIF website).
The createOperation(String) method returns a new instance of a WSIFOperation object. If the operationName value is not valid, or the operation is overloaded, the method throws an exception.
The createOperation(String, String, String) method supports overloaded WSDL operations. We can overload based on the input parameters, but not on the output parameters.
The client must call the close method when a port is no longer in use. In many cases, where the transport is sessionless, such as HTTP, this has no effect. However, if the port is using a session-based protocol such as MQSeries, JMS, or External Call Interface (ECI), this supports the port in caching an open connection to the server and then closing it as required. Responsibly-written applications will call the close method if appropriate.
