Getting Started with WebSphere Application Server

130 Getting Started with WebSphere Application Server Community Edition
portName = "HelloBillPort",
endpointInterface = "com.ibm.wasce.samples.HelloPeople",
targetNamespace = "http://samples.wasce.ibm.com")
public class HelloBill implements HelloPeople {
public String sayHello(String targetName) {
return "Hello " + targetName;
}
}
Listing 7.2 – SEI’s implementation: HelloBill.java
The @WebService annotation properties serviceName, portName, and
targetNamespace shown in the above listing are sample values. It is fine to provide the
@WebService annotation only with values for the endpointInterface property and use
defaults for the rest.
7.2.4 Deploying the Web Service in Community Edition
To publish a Web Service in Community Edition, you need to add some information under
the and elements in the Web project’s WEB-
INF/web.xml file. However, this does not mean that the service class must be a Servlet,
which must extend the HttpServlet. The Web service is never a real servlet; the deployer of
Community Edition can distinguish whether or not it is a Web service implementation class.
Listing 7.3 provides an example of the contents of web.xml.
Hello
com.ibm.wasce.samples.HelloBill
Hello
/Hello
Listing 7.3 - The web.xml file
The element defines how to invoke the Web service from a browser and
also the path to retrieve its WSDL file.
After deploying the Web project to Community Edition, launch a browser and go to the
following URL: http://localhost:8080/HelloServiceProject/Hello
You should see a message from the Axis2 engine as shown in Figure 7.2 below.
