Overview

A client port type can be configured with ports that have different qualities of service. You can use the WebServicesClientBindPreferredPort command-line option to specify which port you want to use.

If you have not deployed the enterprise archive (EAR) file yet, have it ready or already Deploying Web services applications onto appservers into WAS.

You can use Jacl or Jython scripts, but this task assumes you are using Jacl.

For each port type that is configured, one or more ports are available that implement that port type. When a Web service client calls a getPort method, the preferred port mapping determines which port to use. This determination occurs when more than one port can satisfy the getPort method call, such as, a getPort call that specifies the port type, but not the port. For example, suppose the Web service client is configured to use both JMS (JMS) and an HTTP implementation. During installation or management, you can use the WebServicesClientBindPreferredPort command to configure the preferred port of the application to use the transport of choice.

To configure the preferred port mapping with the wsadmin tool proceed with the following steps:

 

Procedure

  1. Launch a scripting command.

  2. At the command prompt for the wsadmin tool, enter the command syntax. You can use install, installInteractive, edit or editInteractive options. The following example is the correct syntax form:

    $AdminApp install app_name {-usedefaultbindings -deployejb -WebServicesClientBindPreferredPort {{module_name EJB_name Web_service port_type port_name}}

    The example shows multiple modules and URL endpoints, because you can edit multiple URL fragments where:

    • app_name is the application name, for example...

      MultiEjbJar.ear

    • EJB_name is the name of the enterprise bean module that is not a Web module, for example,...

      Exchange

    • module_name is the module name, for example...

      ejbclientonly.jar

    • Web_service is the name of the Web service, for example...

      service/StockQuoteService

    • port_type is the port type information, for example...

      {http://stock.multiejbjar.test.wsfvt.ws.ibm.com}StockQuote

    • port_name is the port name, for example...

      {http://stock.multiejbjar.test.wsfvt.ws.ibm.com}StockQuote

 

Results

You have configured Web service client-preferred port mappings with the wsadmin tool.

 

Example

The following example includes the application, module, Web service, port type and port information as it is written in the command line:

$AdminApp install MultiEjbJar.ear {-WebServicesClientBindPreferredPort {{ejbclientonly.jar Exchange service/StockQuoteService {http://stock.multiejbjar.test.wsfvt.ws.ibm.com}StockQuote {http://stock.multiejbjar.test.wsfvt.ws.ibm.com}StockQuote}...}}

The port type information that drives the creation of the WebServicesClientBindPreferredPort option data resides in the client WSDL file. Because valid preferred port mappings are restricted to ports that implement the interface of the port type, validation requires the implementation type of each port. The client WSDL file must be accessed to determine both the type and the implementation information.

The client WSDL file name is in the ServiceRef attribute of the Web service client deployment descriptor. Depending on the module type and version, the client deployment descriptor is located in either the application-client.xml file; the web.xml file, or the ejb-jar.xml file. If you are using J2EE 1.3, the client deployment descriptor information is located in the webservices.xml file.

 

What to do next

Now you can finish any other configurations, start or restart the application, and verify expected behavior of the Web service.
