WebSphere Application Server Network Deployment, Version 6.0.x     Operating Systems: AIX, HP-UX, Linux, Solaris, Windows

Assembling a Web services-enabled client WAR file into an EAR file

Now that you have generated deployment descriptors, located the Web Services Description Language (WSDL) file that was used to develop the Web services client, and generated the necessary classes for the client module, you need to assemble these artifacts to create an enterprise archive (EAR) file that is used in the Web services application.

Before you begin

You can assemble Web Services for J2EE modules with assembly tools provided with WebSphere Application Server.

You must configure the assembly tool before you can use it.

You need the following artifacts that are generated by the WSDL2Java command to complete this task:

Why and when to perform this task

Assemble the client code and artifacts that enable the application client to access a Web service with steps provided:

Steps for this task

  1. Start an assembly tool. The Eclipse assembly tools, Application Server Toolkit (AST) and Rational Web Developer, provide a graphical interface for developing code artifacts, assembling the code artifacts into various archives (modules) and configuring related Java 2 Platform, Enterprise Edition (J2EE) Version 1.2, 1.3 or 1.4 compliant deployment descriptors.
  2. Click File > Import to import the web archive (WAR) file into the assembly tool.
  3. Open the J2EE perspective by clicking Windows >Open Perspective > Other >J2EE.
  4. Switch to the Navigator pane by clicking the Navigator tab.
  5. Locate the project for the file that you just imported in the Navigator pane.
  6. Expand the webContent entry so the WEB-INF directory is displayed. Expand the WEB-INF directory.
  7. Right-click the WEB-INF directory and click New > Folder. Create a subfolder named wsdl in the WEB-INF directory.
    1. Copy the WSDL file to the WEB-INF\wsdl directory by right-clicking the wsdl directory and click Import > File system. Browse the WSDL file for this Web service and click Finish.
    2. Copy the web.xml file. If the WAR module already contains a web.xml file, manually merge the <service-ref> elements in the web.xml file with the original web.xml file that is generated by the WSDL2Java command.
    3. Copy the JAX-RPC mapping file in the WEB-INF subdirectory in the same manner in which you copied the WSDL file. The JAX-RPC mapping file is indicated by the element in the web.xml file.
    4. (Optional) Place the ibm-webservicesclient-ext.xmi file and the ibm-webservicesclient-bnd.xmi file in the WEB-INF subdirectory, if used. If these files are already contained in the WAR module, manually merge the ibm-webservicesclient-ext.xmi and the ibm-webservicesclient-bnd.xmi files that are generated by the WSDL2Java command with the existing files.

Result

You have the artifacts required to enable the client module to use Web services are added to the module.

Example

This example of the assembly process uses the AddressBookWeb.war WAR file and the AddressBook.ear EAR file:
WEB-INF/MANIFEST.MF
WEB-INF/web.xml
WEB-INF/wsdl/AddressBook.wsdl
WEB-INF/AddressBook_mapping.xml
WEB-INF/ibm-webservicesclient-ext.xmi (optional)
WEB-INF/ibm-webservicesclient-bnd.xmi 
com/ibm/websphere/samples/webservices/addr/Address.class
com/ibm/websphere/samples/webservices/addr/AddressBook.class
com/ibm/websphere/samples/webservices/addr/AddressBookClient.class
com/ibm/websphere/samples/webservices/addr/AddressBookService.class
...other generated classes...
After assembling the AddressBookWeb.war file into the AddressBook.ear file, the AddressBook.ear file contains the following files:
META-INF/MANIFEST.MF 
AddressBookWeb.war
META-INF/application.xml

What to do next

Configure the client deployment descriptor . Now that you have assembled the client module, you need to configure the bindings so that the client can communicate with a Web service that is deployed on a server.
