First, the demand

• The previous section, although binding WebService and Web projects together, does not share a single port, this chapter explains WebService and Web project bindings and common ports.

Ii. Case 2.1 Create a Web project and introduce a dependency

2.2 Authoring The Service interface

 Package Service; Import Javax.jws.WebParam; Import Javax.jws.WebResult; Import Javax.jws.WebService; @WebService (targetnamespace= "http://www/shyroke.com/")  Public Interface Ifirst {    = "Addresult")    publicintint int  y);}

2.3 Writing the service interface proxy class

 Package Service; Import Javax.jws.WebService; @WebService (endpointinterface= "service. Ifirst ")publicclassimplements  ifirst{    public  int Add (intint  y) {        return x+y;    }    }

2.4 Build and write Sun-jaxws.xml in the Web-inf directory

<?XML version = "1.0"?><Endpointsversion= "2.0"xmlns= "Http://java.sun.com/xml/ns/jax-ws/ri/runtime">    <Endpointname= "First"Implementation= "service. Firstdelegate "Url-pattern= "/firstport">    </Endpoint></Endpoints>

• Where Url-pattern Browse the address of the Webserice service for the browser,implementation is the proxy class for the service interface

2.5 Configuring Web. Xml

<!DOCTYPE Web-app Public "-//sun Microsystems, INC.//DTD Web Application 2.3//en" "http://java.sun.com/dtd/web-app_2 _3.dtd "><Web-app>    <Listener>        <Listener-class>Com.sun.xml.ws.transport.http.servlet.WSServletContextListener</Listener-class>    </Listener>    <servlet>        <Servlet-name>Public</Servlet-name>        <Servlet-class>Com.sun.xml.ws.transport.http.servlet.WSServlet</Servlet-class>        <Load-on-startup>1</Load-on-startup>    </servlet>    <servlet-mapping>        <Servlet-name>Public</Servlet-name>        <Url-pattern>/firstport</Url-pattern>    </servlet-mapping></Web-app>
