Building and Deploying Web Services to Sun Java System Web Server 7.0 With the NetBeans 5.0 IDE

By Krishnamohan (Krishna) Meduri, Marina Sum, August 11, 2006  

This article describes how to build and test Web services that are based on Java API for XML Web Services (JAX-WS) 2.0 with the built-in capabilities of the NetBeans 5.0 IDE and the plug-in for Sun Java System Web Server 7.0 (henceforth, Web Server 7.0), now in Technology Preview 2. In this article, you also learn how to deploy and debug Web services.

This article assumes the following:

Note: Some of the URLs in this article contain localhost and assume that the server instance is running on localhost on port 80. Replace localhost with hostname : portnumber, as appropriate.

Creating a Web Application

Before building a Web service, first create a Web application:

  1. From the NetBeans IDE, choose File > New Project (Ctrl+Shift+N).

    The New Project wizard is displayed.
  2. Select Web under Categories and Web Application under Projects. Click Next.

    The New Web Application wizard is displayed.
  3. Type HelloWebService in the Project Name text field, specify the directory in the Project Location text field, and choose Sun Java System Web Server 7.0 from the Server drop-down list.
  4. Deselect the checkbox Set Source Level to 1.4 so as to set the source level to 1.5 to enable support for annotations.
  5. Click Next and then click Finish. See Figure 1.

    Figure 1: Creating a Web Application
    Figure 1: Creating a Web Application (Click image for larger view.)
Building a Web Service

Now create a Web service, starting from a service endpoint. Eventually, you will turn the Web application you just created into a Web service.


Creating and Adding a Service Class to the Web Application

First, create and add a service class to the HelloWebService Web application:

  1. In Projects view, right-click the HelloWebService node and choose New > Java Class.

    The New Java Class wizard is displayed.
  2. Type ServiceImpl in the Class Name text field and my.sample.server in the Package text field. Click Finish.
  3. In Projects view, double-click under Source Packages to open the file for editing.
  4. Implement a hello(java.lang.String) operation and specify the portType name, the service name, and the target namespace with JAX-WS 2.0 annotations, as follows.
package my.sample.server;

import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.WebMethod;

 * A simple Java class that will become a Web service.
@WebService(name="Hello", serviceName="HelloService", targetNamespace="")
public class ServiceImpl {

    public String hello(@WebParam(name="name") String s) {
        System.out.println("Service received: " + s);
        return "Hello "+s;


Modifying the web.xml File

Next, modify the web.xml file to specify the JAX-WS servlet class and the servlet context listener:

  1. Expand the HelloWebService project node, the Web Pages node, and the WEB-INF node.
  2. Right-click the web.xml file and choose Edit from the context menu to open the file for editing.
  3. Make the file read as follows:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns=""


Creating a sun-jaxws.xml File

Next, create a sun-jaxws.xml file, which is used by the JAX-WS runtime to specify the implementation class and relative URL for the service endpoint. Create that file under Web Pages/WEB-INF, as follows:

  1. Right-click WEB-INF and choose New > File/Folder from the context menu.

    The New File wizard is displayed.
  2. Select XML under Categories and XML Document under File Types. Click Next.

    The Name and Location pane is displayed.
  3. Type sun-jaxws in the File Name text field. Click Next.

    The Select Document Type pane is displayed.
  4. Select Well-formed Document. Click Finish.
  5. Double-click the sun-jaxws.xml file for editing. Make its content read as follows:

    <?xml version="1.0" encoding="UTF-8"?>
    <endpoints xmlns="#" version="2.0">


Modifying the build.xml File

As a final step, add the Ant target -pre-dist to the project's build.xml file:

  1. Switch from Projects view to Files view by clicking the Files tab.
  2. Expand the HelloWebService node and double-click build.xml for editing.
  3. Add the -pre-dist Ant target to build.xml, as follows.

    <!-- Overrides the build-impl.xml target to create the server artifacts that will be
    included in the WAR file. -->
    <target name="-pre-dist">
        <taskdef name="wsgen" classname="">
            <classpath path="${javac.classpath}:${j2ee.platform.classpath}"/>
                <pathelement path="${javac.classpath}:${j2ee.platform.classpath}"/>
                <pathelement location="${java.home}/../lib/tools.jar"/>
                <pathelement location="build/web/WEB-INF/classes"/>

After compiling your service class but before creating the WAR file, the NetBeans IDE calls the -pre-dist target. That target calls the wsgen Ant task, which creates the Java Architecture for XML Binding (JAXB) and JAX-WS files that are required for the Web service. For details on wsgen, see the JAX-WS documentation.

Deploying and Testing the Web Service

Now build and deploy the project:

  1. In Projects view, right-click HelloWebService and choose Build Project from the context menu.

    The NetBeans IDE compiles the source files for the HelloWebService project and creates a HelloWebService.war file.
  2. Still in Projects view, right-click HelloWebService and choose Deploy Project from the context menu.

    The NetBeans IDE deploys the project to the configuration on Web Server 7.0.

Next, run the Web project by choosing Run > Run Main Project from the main menu. The NetBeans IDE opens http://localhost/HelloWebService in the browser and shows the welcome page ( index.jsp in this case). To see the related information for HelloWebService, go to http://localhost/HelloWebService/hello.

Note this optional but helpful procedure:

  1. Right-click the project name, HelloWebSevice in this case, and choose Properties from the context menu.

    The Project Properties dialog box is displayed.
  2. Select the Run node and type /hello in the Relative URL text field.

    When you run the project, the NetBeans IDE displays the appropriate URL, http://localhost/HelloWebService/hello in this case, in a Web browser. That way, you can verify that the Web service has been deployed and browse the Web Services Description Language (WSDL) file. You can also edit the service class and verify the changes in the WSDL file by simply pressing F6 to rebuild and deploy the service.

Normally, the Hello service information is displayed in the browser as follows, which indicates that deployment was successful.

Port Name
Address: http://localhost/HelloWebService/hello
WSDL: http://localhost/HelloWebService/hello?wsdl
Port QName: {}HelloPort
Implementation class: my.sample.server.ServiceImpl


Testing the Web Service in the Web Service Registry

The simplest way to test the Web service is by using the Web Services Registry in the NetBeans IDE. Follow these steps:

  1. Click the Runtime tab, right-click Web Services, and then choose Add Web Service from the context menu.

    The Add Web Service wizard is displayed.
  2. In the URL field, type the address of the Web service WSDL file, http://localhost/HelloWebService/hello?wsdl in this case.
  3. Click Get Web Service Description.

    The information that pertains to the Web service is displayed. See Figure 2.

    Figure 2: Displaying the Web Service Information
    Figure 2: Displaying the Web Service Information
  4. Click Test Operation to the left of the operation name to test the hello() operation.

    The Test Web Service Operation dialog box is displayed.
  5. Type a value in the Value text field and click Submit.

    The NetBeans IDE displays the result in the Results area. See Figure 3.

    Figure 3: Testing the hello() Operation
    Figure 3: Testing the hello() Operation


Testing the Web Service With a JUnit Test as a Client

To test the Web service with a JUnit test as a client, use the test capabilities in the NetBeans 5.0 IDE. Follow these steps:

  1. Create a new JUnit test:

    1. Click the Projects tab and expand the HelloWebService node.
    2. Right-click the Test Packages node and choose New > File/Folder from the context menu.

      The New File wizard is displayed.
    3. Select JUnit under Categories and Empty Test under File Types. Click Next.

      The New Empty Test pane is displayed.
    4. Type ServiceTest in the Class Name text field and my.sample.test in the Package text field. Click Finish.
    5. Double-click for editing and implement the testService() method, as follows.

      package my.sample.test;
      import junit.framework.*;
      import my.sample.test.generated.Hello;
      import my.sample.test.generated.HelloService;
      public class ServiceTest extends TestCase {
          public ServiceTest(String testName) {
          protected void setUp() throws Exception {
          protected void tearDown() throws Exception {
          // TO DO: Add test methods here. The name must begin with "test." For example,
          public void testService() {
              HelloService service = new HelloService();
              Hello proxy = service.getHelloPort();
              String request = "Sun Java System Web Server 7.0 User";
              String response = proxy.hello(request);
  2. Modify the HelloWorldService project's build.xml file.

    1. Replace localhost with hostname : portnumber, as appropriate, in the -pre-compile-test Ant target below and add the target.

      <!-- Overrides the build-impl.xml target to start the server and generate client artifacts
      before building the test. -->
      <target name="-pre-compile-test">
          <taskdef name="wsimport" classname="">
              <classpath path="${javac.classpath}:${j2ee.platform.classpath}"/>
          <!-- Use "debug" or "run" here. -->
          <antcall target="run"/>
          <echo>running wsimport</echo>
      Before compiling and running your test client, the NetBeans IDE calls -pre-compile-test. When that target is run, the IDE ensures that the service is built and deployed and, if necessary, rebuilds the service. For details on wsimport, see the JAX-WS documentation.
    2. Add the -init-macrodef-junit Ant target and append ${j2ee.platform.classpath} to the classpath, as follows.

      <target name="-init-macrodef-junit">
          <macrodef name="junit" uri="">
              <attribute name="includes" default="**/*"/>
                  <junit showoutput="true" fork="true" dir="${basedir}"
                   failureproperty="tests.failed" errorproperty="tests.failed">
                      <batchtest todir="${build.test.results.dir}">
                          <fileset dir="${test.src.dir}" includes="@{includes}"/>
                          <path path="${run.test.classpath}:${j2ee.platform.classpath}"/>
                          <propertyref prefix="test-sys-prop."/>
                          <mapper type="glob" from="test-sys-prop.*" to="*"/>
                      <formatter type="brief" usefile="false"/>
                      <formatter type="xml"/>
      That way, you are effectively overriding the -init-macrodef-junit target of the project's build-impl.xml file.
  3. Run the test: Select the HelloWebService project and choose Run > Test "HelloWebService" from the main menu.

    In the Statistics tab in the JUnit Tests results frame, you will see "passed." In the Output tab, you will see "Hello Sun Java System Web Server 7.0 User," which is returned from the Web service. If you change the request string in testService() to "World" and run the client again, you will see "Hello World."
Debugging Web Applications

To debug Web applications, right-click the project name in the NetBeans IDE and choose Debug Project from the context menu. The NetBeans IDE then starts the Web Server 7.0 instance in debug mode.

Alternatively, you can enable debugging as follows:

  1. Start the Web Server 7.0 Admin Console at https://localhost:8989/, assuming that the installation is on localhost with the default settings.
  2. Accept the certificate and then log in to the Admin Console.
  3. Click the Common Tasks tab and choose the appropriate configuration from the drop-down list.
  4. Click the Edit Java Settings button for the next page.
  5. Click the JVM Settings tab and, under Debug Java Settings, select the Enable Debug checkbox. Click Save.
  6. Click the Deployment Pending link in the top right corner.

    The Configuration Deployment page is displayed.
  7. Click Deploy and then click Close.
  8. Click Home in the top right corner and then click Start/Stop Instances in the Common Tasks tab for the next page.
  9. Select the checkbox for the node and Click start.

Next, in the NetBeans IDE:

  1. Choose Run > Attach Debugger from the main menu.

    The Attach dialog box is displayed.
  2. Type the host name, as appropriate, in the Host text field and 7896 in the Port text field. Click OK. See Figure 4.

    Figure 4: Debugging in the NetBeans IDE
    Figure 4: Debugging in the NetBeans IDE

The debugger stops executing the program at the breakpoint you have set in the application.

To set a breakpoint, right-click a Java statement and choose Toggle Breakpoint (Ctrl+F8) from the context menu. You can set breakpoints in both service code and client code.

When debugging is complete, choose Run > Finish Debugger Session from the main menu to end the process.

Appendix: Creating Web Services From WSDL

This appendix describes how to create a Web service from WSDL. As an example, use the AddNumbers.wsdl file in the JAX-WS2.0/samples/fromwsdl directory.

Follow these steps:

  1. Copy the AddNumbers.wsdl file to the HelloWebService/web/WEB-INF/wsdl directory.
  2. Add the following <servlet-mapping> entry to the web.xml file.

  3. Add the following <endpoint> entry to the sun-jaxws.xml file.

    <endpoint name="AddNumbers"
  4. Create a -pre-compile target, to be executed before the compile target, with the wsimport task, as follows.

    <!-- Overrides the -pre-compile target in build.xml to create jax-ws java artifacts that
    will be created and compiled to the WEB-INF/classes directory. -->
    <target name="-pre-compile">
        <taskdef name="wsimport" classname="">
            <classpath path="${javac.classpath}:${j2ee.platform.classpath}"/>
        <echo>running wsimport</echo>
        <!-- wsdl attribute is absolute path, so ${basedir} is included -->
    The -pre-compile target calls the <wsimport> task, which generates all the necessary Java artifacts from the WSDL file and the referenced schema files. Those artifacts are generated in the WEB-INF/classes directory with the wsimport.generated.addnumbers package.
  5. Create a service implementation class, for example, in the same package as the ServiceImpl class, as follows.

    Note: The implementation class must implement the Service Endpoint Interface generated by wsimport.

    package my.sample.server;
    import javax.jws.WebService;
    import wsimport.generated.addnumbers.*;
     * A simple Java class to implement a Web service. Until the endpoint interface is
     * generated, the class declaration below will show up as a compiler error.
    public class AddNumbersImpl implements AddNumbersPortType {
        public void oneWayInt(int arg0) {
            System.out.println("received value "+arg0);
        public int addNumbers(int arg0,int arg1) throws AddNumbersFault_Exception {
            if (arg0<0 || arg1<0) throw new AddNumbersFault_Exception("negative number",
                                                                            new AddNumbersFault());
            return arg0+arg1;
  6. Build and deploy the project.

    If you then run the project, the following information is displayed on the browser:

    Port Name
    Address: http://localhost/HelloWebService/hello
    WSDL: http://localhost/HelloWebService/hello?wsdl
    Port QName: {}HelloPort
    Implementation class: my.sample.server.ServiceImpl
    Address: http://localhost/HelloWebService/addNumbers
    WSDL: http://localhost/HelloWebService/addNumbers?wsdl
    Port QName: {}AddNumbersPort
    Implementation class: my.sample.server.AddNumbersImpl
    You can then test the new Web service in the Web Services Registry.
