Developing a Service using JAX-WS

...

package com.iona.demo;

import javax.jws.*;

@WebService(name="quoteUpdater",
            targetNamespace="http:\\cxf.apache.org",
	    serviceName="updateQuoteService",
            wsdlLocation="http:\\cxf.apache.org\quoteExampleService?wsdl",
            portName="updateQuotePort")
public interface quoteReporter
{
  public Quote getQuote(@WebParam(name="ticker") String ticker);
}

The @WebService annotation in #Example4 does the following:

1. Specifies that the value of the name attribute of the wsdl:portType element defining the service interface is quoteUpdater.
2. Specifies that the target namespace of the service is http:
cxf.apache.org.
3. Specifies that the value of the name of the wsdl:service element defining the published service is updateQuoteService.
4. Specifies that the service will publish its WSDL contract at http:\\cxf.apache.org\quoteExampleService?wsdl.
5. Specifies that the value of the name attribute of the wsdl:port element defining the endpoint exposing the service is updateQuotePort.

The @WebParam annotation is necessary as java interfaces do not store the Parameter name in the .class file. So if you leave out the annotation your parameter will be named arg0.
