Java web service client applications use a web service proxy client to interact with the Web services APIs. A proxy client allows the developer to invoke the web service APIs as if it was a local method. For generating a web service proxy client, we need the WSDL files that describe the web service interfaces. The WSDL files for business process API is BFMWS.wsdl and for human task API is HTMWS.wsdl. The steps in generating a web service are as follows. (Before following the steps, copy your WSDL files to your workspace or to some location where the WID/RAD can see your WSDL files.

Step 1.
Right click on the web project (from web perspective) and select New -> Other. The select wizard opens. Expand the web service folder and select ‘Web Service Client’.

Click Next.

Step 2.
From the web service client dialog box, accept the default values (The client proxy type would be Java Proxy, and ‘Create Folders when necessary’ checkbox would be checked and all other check boxes would be unchecked) or select the options that matches your environment.

Click Next.

Step 3.
The web service selection page opens. Click on Browse button. From the opened resource browser window, select the WSDL file. Click OK.

Click Next.

Step 4.
The client environment configuration window opens. From this page select ‘IBM WebSphere’ as the Web service runtime by clicking the Edit button, if it is not selected already. Select the client type and the client projects.

Click Next.

Step 5.
The web service proxy client page appears. Accept all the default values.

Click Finish.

The web service proxy client will be generated and we can use the generated proxy client and helper classes for invoking the web service from our client application.
