This subsection describes how to develop a Web Service client using Web applications.

Organization of this subsection
(1) Flow of Web Service client development using Web applications
(2) Creating a dynamic Web project
(3) Acquiring a WSDL file
(4) Generating a Java source
(5) Implementing a Web Service client
(6) Editing web.xml

(1) Flow of Web Service client development using Web applications

The following figure shows the flow of Web Service client development using Web applications:

Figure 8-4 Flow of Web Service client development using Web applications

[Figure]

An overview of the individual operations is as follows:

  1. Creating a dynamic Web project
    Create a dynamic Web project to be used for developing a Web Service client. For details, see 8.4.2(2) Creating a dynamic Web project.
  2. Acquiring a WSDL file
    Acquire a WSDL file or acquire the URL of a released WSDL file. For details, see 8.4.2(3) Acquiring a WSDL file.
  3. Generating a Java source
    Generate the Java source for implementing the Web Service client. For details, see 8.4.2(4) Generating a Java source.
  4. Implementing a Web Service client
    Use the generated Java source to implement the Web Service client. For details, see 8.4.2(5) Implementing a Web Service client.
  5. Editing web.xml
    Add the definition of JSPs and servlets implementing the Web Service client. For details, see 8.4.2(6) Editing web.xml.
  6. Creating an enterprise application project and adding a module
    Create an enterprise application project and add the dynamic Web project. For details, see 8.4.2(7) Creating enterprise application projects and adding modules.
  7. Deploying and debugging J2EE applications
    You deploy and then debug J2EE applications in the J2EE server. For details, see 8.4.2 (8) Deploying and debugging J2EE applications.

The following subsections describe the development of a Web Service client using the Web applications, according to the above flow.

(2) Creating a dynamic Web project

Create a dynamic Web project to be used for developing a Web Service client using Web applications. For details on how to create dynamic Web projects, see the subsection 4.4.1 Creating a dynamic Web project.

(3) Acquiring a WSDL file

Acquire a WSDL file that describes the meta information of Web Services you are trying to invoke, or if the URL of the WSDL file has been released, acquire that URL.

(4) Generating a Java source

Based on the acquired WSDL file, generate the Java source (service class, SEI, and Java Bean (stub)) required for developing and executing the Web Service client. You can use Eclipse to generate the Java source. The procedure of generating the Java source is same as described in the subsection 8.4.1(4) Generating a Java source, however in Project in the Web Service Client dialog box, select dynamic Web project name of the workspace.

When the following operations or settings are performed and the Web Service Client dialog box appears, the Java source folder selection becomes blank and the subsequent operations can no longer be performed. Therefore, specify a folder other than the project root in Java source folder.

(5) Implementing a Web Service client

Use the generated Java source to implement the Web Service client. For the examples of implementing a Web Service client, see 3.6 Implementing a Web Service client in the manual uCosminexus Application Server Web Service Development Guide.

(6) Editing web.xml

In web.xml, add the definition of JSPs and servlets that implement the Web Service client.

(7) Creating enterprise application projects and adding modules

(a) Creating enterprise application projects

Create the enterprise application projects. For details on how to create the enterprise application projects, see the subsection 4.4.4 Creating an enterprise application project.

(b) Adding modules in enterprise application projects

In the enterprise application project, add dynamic Web project for the Web Service client created in 8.4.2(2) Creating a dynamic Web project. To add a dynamic Web project:

  1. On the EAR Application Project page of the New EAR Application Project dialog box, click the Next button.
    The Enterprise Application page appears.
  2. Select the module to be added, and then click the Finish button.

(8) Deploying and debugging J2EE applications

Deploy and debug the created projects.

(a) Deploying J2EE applications

On the J2EE server, deploy the J2EE applications that are created from the enterprise application project. For details on how to deploy the J2EE applications, see the subsection 6.7 Releasing a project on a J2EE server.

(b) Debugging J2EE applications

Debug the created J2EE applications. For details on how to debug the J2EE applications, see the subsection 6.8 Debugging and executing J2EE applications.
