Publishing WSDL files using the wsadmin tool

The Web Services Description Language (WSDL) files in each Web services-enabled module are published to the file system location you specify. We can provide these WSDL files in the development and configuration process of Web services clients so that they can invoke your Web services.

 

Before you begin

Before you publish a WSDL file, we can configure Web services to specify endpoint information in the form of URL fragments to enable full URL specification of WSDL ports. Refer to the tasks describing configuring endpoint URL information. To publish a Web Services Description Language (WSDL) file we need an enterprise application, also known as an enterprise archive (EAR) file, that contains a Web services-enabled module and has been deployed into WebSphere Application Server. See Deploying Web services based on Web Services for Java 2 platform, Enterprise Edition (J2EE).

 

About this task

The purpose of publishing the WSDL file is to provide clients with a description of the Web service, including the URL identifying the location of the service.

After installing a Web services application, and optionally modifying the endpoint information, you might need WSDL files containing the updated endpoint information. We can obtain the updated WSDL files by publishing them to the file system. If you are a client developer or a system administrator, use WSDL files to enable clients to connect to a Web service.

The wsadmin tool can publish the WSDL files in either local, for example, -conntype NONE, or remote mode. However, in local mode, locate the target application at the same node where the wsadmin command is invoked.

The following steps assume that the application has been deployed and that the application server is running.

 

Procedure

  1. Start the wsdamin tool from the command prompt using the following commands:

    • install_root\bin\wsadmin

    • install_root/bin/wsadmin

  2. At the wsadmin command prompt, enter one of the two commands:

    • $AdminApp publishWSDLapp_name path_name

    • $AdminApp publishWSDLapp_name path_name soapAddressPrefixes

    where:

    • app_name is the application name

    • path_name is the absolute path to the zip file that contains the published WSDL files. The zip file is saved on the machine that runs WebSphere Application Server, therefore, if the server is running on a different machine, we need to obtain the zip file from that machine. The directory structure of the resulting zip file is based on the following information

      Application_file_name/module_file_name/META-INF/ or WEB-INF/wsdl/WSDL_file_name 
      
      See the usage scenario for an example of this directory structure.

    • soapAddressPrefixes is a parameter of the form {{module {{binding partial-url}}}}. This parameter describes the partial URL information for each binding on a per-module basis for the application.

      • module identifies the name of the module

      • binding is either http or jms (both are in lower case)

      • partial-url is the partial SOAP address for the associated SOAP binding. For an HTTP binding, the form is http://host:port/ or https://host:port.

        For Java Message Service (JMS) bindings, the form is

        jms:/queue?destination=dest&connectionFactory=cf
        
        or
        jms:/topic?destination=dest&connectionFactory=cf
        

Use the $AdminApp publishWSDL app_Name path_Name command to publish WSDL files with default endpoint URL addresses. If you want to modify the SOAP address prefixes of the WSDL file, use the other form of the command.

Use the $AdminApp publishWSDL app_Name path_Name {{module {{binding partial-url}}}} command to customize the WSDL SOAP address for each module. We can specify a different address prefix for each SOAP binding.

 

Results

The WSDL files from Web services are published to a specified zip file. The zip file can be used to create a Web service client that accesses the deployed service. The published WSDL files do not contain enterprise JavaBean (EJB) binding information.

 

Example

The command to publish WSDL files for a Web service named WebServicesSamples can be $AdminApp publishWSDL WebServicesSamples c:/temp/samplesWsdl.zip

or

$AdminApp publishWSDL WebServicesSamples c:/temp/sampleswsdl.zip { {AddressBookJ2WB.war {{http http://localhost:9080}}} {StockQuote.jar {{http https://localhost:9443}}} }

The directory structure for this created zip file is

WebServicesSamples.ear/StockQuote.jar/META-INF/wsdl/StockQuoteFetcher.wsdl 
WebServicesSamples.ear/AddressBookW2JE.jar/META-INF/wsdl/AddressBookW2JE.wsdl 
WebServicesSamples.ear/AddressBookJ2WE.jar/META-INF/wsdl/AddressBookJ2WE.wsdl 
WebServicesSamples.ear/AddressBookJ2WB.war/WEB-INF/wsdl/AddressBookJ2WB.wsdl 
WebServicesSamples.ear/AddressBookW2JB.war/WEB-INF/wsdl/AddressBookW2JB.wsdl

 

What to do next

Develop a Web services client or configure the endpoint information for an existing Web service.
