23.3. Adding a Port to a Service


The endpoint information for a service is defined in a wsdl:port element, and the Service object creates a proxy instance for each of the endpoints defined in a WSDL contract, if one is specified. If you do not specify a WSDL contract when you create your Service object, the Service object has no information about the endpoints that implement your service, and therefore cannot create any proxy instances. In this case, you must provide the Service object with the information needed to represent a wsdl:port element using the addPort() method.

The addPort() method

The Service class defines an addPort() method, shown in Example 23.3, “The addPort() Method”, that is used in cases where there is no WSDL contract available to the consumer implementation. The addPort() method allows you to give a Service object the information, which is typically stored in a wsdl:port element, necessary to create a proxy for a service implementation.

Example 23.3. The addPort() Method

void addPort(QName portName,
             String bindingId,
             String endpointAddress)
    throws WebServiceException;
The value of the portName is a QName. The value of its namespace part is the target namespace of the service. The service's target namespace is specified in the targetNamespace property of the @WebService annotation. The value of the QName's local part is the value of wsdl:port element's name attribute. You can determine this value in one of the following ways:
  1. Specify it in the portName property of the @WebService annotation.
  2. Append Port to the value of the name property of the @WebService annotation.
  3. Append Port to the name of the SEI.
The value of the bindingId parameter is a string that uniquely identifies the type of binding used by the endpoint. For a SOAP binding you use the standard SOAP namespace: If the endpoint is not using a SOAP binding, the value of the bindingId parameter is determined by the binding developer.
The value of the endpointAddress parameter is the address where the endpoint is published. For a SOAP/HTTP endpoint, the address is an HTTP address. Transports other than HTTP use different address schemes.


Example 23.4. Adding a Port to a Service Object

package com.fusesource.demo;

import javax.xml.namespace.QName;

public class Client
public static void main(String args[])
1    QName portName = new QName("", "stockQuoteReporterPort");
2    s.addPort(portName, 
3              "", 
4              "http://localhost:9000/StockQuote");
Creates the QName for the portName parameter.
Calls the addPort() method.
Specifies that the endpoint uses a SOAP binding.
Specifies the address where the endpoint is published.
