   This completes the creation of wsdl for web service.

Creating the Web Services Implementation code

To implement the Calculator we are going to create a package org.apache.geronimo.samples.jws. This package will contain 2 classes. A Calculator Interface, and CalculatorService which implements the Calculator interface. Lets go step by step with creating the package, interface class and implementation class.

...

1. Right click on the package org.apache.geronimo.samples.jws and select
   New->Class.
2. Name the class CalculatorService
3. Accept all the defaults and Select Finish.
   
   
   
   
   
   
4. Add the following code to CalculatorService.class

   Code Block
   title CalculatorService.class borderStyle solid
   package org.apache.geronimo.samples.jws; import javax.annotation.Resource; import javax.jws.WebService; import javax.xml.ws.WebServiceContext; @WebService(serviceName = "Calculator", portName="CalculatorPort", endpointInterface = "org.apache.geronimo.samples.jws.Calculator", targetNamespace = "http://jws.samples.geronimo.apache.org") public class CalculatorService implements Calculator { @Resource private WebServiceContext context; /** * @return * returns javax.xml.ws.WebServiceContext */ public WebServiceContext getContext() { return context; } /** * @param value1 * @param value2 * @return * returns int */ public int add(int value1, int value2) { System.out.println("User Principal: " + context.getUserPrincipal()); System.out.println("value1: " + value1 + " value2: " + value2); return value1 + value2; } }

This completes the development of Web Services implementation code.

Developing a web client for Calculator

This section will take you through the creation of two jsp's index.jsp and result.jsp.index.jsp will prompt the
user to enter two whole number values to add together. After submitting the form, the action will be forwarded to result.jsp. Result.jsp will call the Calculator add Web Service.

1. Right Click on the Web Content folder and Select New->JSP.
2. Name the jsp as index.jsp and Select Finish.
   Image Added
3. Add the following code to index.jsp

   Code Block
   title index.jsp borderStyle solid
   <%@ page import="java.net.URL,javax.xml.namespace.QName,javax.xml.ws.Service,org .apache.geronimo.samples.jws.Calculator"%> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <title>Calculator</title> </head> <body> <form action="result.jsp"> Please enter 2 whole numbers to add: <input type="text" name="value1"> + <input type="text" name="value2"> <input type="submit" value="="> </form> </body> </html>

4. Right Click on the Web Content folder and Select New->JSP.
5. Name the jsp as result.jsp and Select Finish.
6. Add the following code to jsp.

   Code Block
   title result.jsp borderStyle solid
   <%@ page import="java.net.URL,javax.xml.namespace.QName,javax.xml.ws.Service,org .apache.geronimo.samples.jws.Calculator"%> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head> <title>Calculator Result</title> </head> <% int value1 = 0; int value2 = 0; int sum = 0; try { System.out.println( request.getParameter( "value1" ) + " " + request.getParameter( "value2" ) ); value1 = Integer.parseInt( request.getParameter( "value1" ) ); value2 = Integer.parseInt( request.getParameter( "value2" ) ); URL url = new URL("http://localhost:8080/jaxws-calculator- 1.0/calculator?wsdl"); QName qname = new QName("http://jws.samples.geronimo.apache.org", "Calculator"); Service service = Service.create(url, qname); Calculator calc = (Calculator)service.getPort(Calculator.class); sum = calc.add(value1, value2); } catch ( Exception e ) { e.printStackTrace(); } %> <body> The result is: <%=value1%>+<%=value2%>=<%=sum%> <br> <a href="index.jsp">Back</a> </body> </html>

This finishes the development of Web client.
