...

This tutorial will walk you through building and developing the JAX-WS calculator that ships with the samples package for Geronimo. After completing this tutorial, you should be able to understand how to build simple Web services with Apache Geronimo
using the Eclipse development environment.

...

  1. Sun JDK 6.0+ (J2SE 1.6)
  2. Eclipse IDE for Java EE Developers, which is platform specific
  3. Apache Geronimo Eclipse Plugin 2.2.x
  4. Apache Geronimo Server 2.2.x

    Note

    Geronimo version 2.2, Java 1.6 runtime, and Eclipse Ganymede are used is used in this tutorial but other versions can be used instead (for example, Geronimo version 2.1, Java 1.5, Eclipse Europa)

Details on installing eclipse are provided in the Development environment section. This tutorial is organized in the following sections:

Setting Eclipse for application development

...

  1. Select File -> New, select Other....



  2. In the popup window select Web -> Dynamic Web Project category and click Next.



  3. Type in jaxws-calculator as the Project name and select Next.



  4. Make sure Generate Deployment Descriptor is selected and click Next.



  5. Modify the Group Id to: org.apache.geronimo.samples.jws and Artifact Id to: Calculator.

    Infotitle


    Useful Information
    • Group ID: A name that identifies the group of a module. The default value is default.
    • Artifact ID: A name of the module in a group. The default value is <blank>.
    • Version: The version of module. The default value is 1.0
    • Type: The type of module, such as system module (car), jar module (jar), web archive (war), enterprise archive (ear), and so on. The default value is car. A module is stored inside a repository as repository/groupId/artifactId/version/artifactIdversion.
      type. This repository structure gives a more standardized and easily maintainable
      structure to Geronimo applications.

Axis2 configuration

  1. Select Window -> Preferences.



  2. Select Web Services -> Axis2 Preferences.
  3. Under Axis2 Runtime tab, browse to the installation root of the Axis2 runtime installation to be used in Eclipse. Select OK. Infotitle Useful Information

    A separate Axis2 runtime is required for use by the Eclipse Axis2 project facet. You can use the pre-integrated Axis2 1.4 binaries (axis-1.4.jar) from the local Geronimo repository under <Geronimo_home>/repository/axis/axis/1.4
  4. Righ click on the jaxws-calculator project and select Properties, then select Project Facets.
  5. On the next screen check the box for Axis2 Web Services.



  6. Select Finish.
    This completes the configuration of Eclipse for application development.

...

  1. Right click on Java Resources: src and select New -> Package.



  2. Name the package as org.apache.geronimo.samples.jws. Select Finish.



  3. Right click on the new package and Select New -> Interface.



  4. Name the interface as Calculator. Select Finish.



  5. Add the following code to the Calculator interface class: Code BlockborderStylesolidtitleCalculator.class solid package org.apache.geronimo.samples.jws; import javax.jws.WebService; import javax.jws.WebMethod; import javax.jws.WebParam; @WebService(name="CalculatorPortType", targetNamespace = "targetNamespace = "http://jws.samples.geronimo.apache.org") public interface Calculator { @WebMethod public int add(@WebParam(name = "value1") int value1, @WebParam(name = "value2") int value2); }
  6. Right click on the package org.apache.geronimo.samples.jws and select New -> Class.
  7. Name the class CalculatorService.
  8. Accept all the defaults and Select Finish..



  9. Add the following code to CalculatorService class: Code BlockborderStylesolidtitleCalculatorService.class 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; public int add(int value1, int value2) { System.out.println("User Principal: " + context.getUserPrincipal()); return value1 + value2; } }

Let us try to understand each annotation.

...

  • Export the source files to a jar as shown in the following three figures.









  • Open a command prompt and point it to the bin directory of server installation.
    1. Run the command: Code BlockborderStylesolidtitleWSDL Generation command solid Administrator@T60J9:/> jaxws-tools.bat wsgen -classpath C:/WSDL/source.jar -d C:/WSDL/ -wsdl:soap1.1 org.apache.geronimo.samples.jws.CalculatorService In this command -classpath is used to set the source.jar exported from Eclipse in the classpath, -d defines the location where all the generated artifacts will be placed, -wsdl:soap1.1 suggests a WSDL generation following soap1.1 protocol, and org.apache.geronimo.samples.jws.CalculatorService is the SEI used to generate the WSDL.
    2. Once the above command is run Calculator_schema1.xsd and Calculator.wsdl will be generated at C:/WSDL/.

    3. Rename Calculator.wsdl as CalculatorService.wsdl and add both the generated files to WEB-INF directory of the project.

...

  1. Right click on the Web Content folder and Select New --> JSP.

  2. Name the JSP as index.jsp and select Finish.



  3. Add the following code to index.jsp: Code BlockborderStylesolidtitleindex.jsp 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 result.jsp: Code BlockborderStylesolidtitleresult.jsp 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.
