Java Client Application for Real-time Web Services

This section provides instructions for using the Axis Web Services Toolkit to create a Java client application program that calls a PowerCenter real-time web service. For more information about using the Axis Web Services Toolkit see the documentation on the Apache web site:

http://ws.apache.org/axis/java/user-guide.html

Before you create the client application that calls a PowerCenter web service workflow, you must first create the web service workflow and generate the WSDL for the web service. You then create the client application based on the web service WSDL.

To create a PowerCenter web service and generate the WSDL, complete the following steps:

Create a mapping for the web service workflow. You can create a mapping to receive a message from a web service client, transform the data, and send the response back to the web service client or write it to any target that PowerCenter supports.

Create a workflow and enable it as a web service. Create a workflow to run the mapping and enable the Web Services option in the workflow properties. Select the Runnable option so that client applications outside of PowerCenter can run the workflow.

Locate and download the WSDL for the web service workflow. When you create the web service workflow, PowerCenter generates a WSDL for the web service. If you configure the web service to be visible, you can view the WSDL on the console of the Web Services Hub associated with the web service.

After you create the web service, you can develop a client application to run the web service workflow.
