System requirements

To prepare for this tutorial, you need to do the following:

• Install WebSphere Application Server v6.x. We recommend you set up one system for hosting the Web service and another for hosting the gateway server.
• Download and unzip the sample Web service and client applications (see Downloads). They include a service EAR file and a client EAR file. Both client and service are WS-Security enabled.
• Install the Web service EAR file and start it in the hosting WebSphere Application Server v6.x.
• Enable global security on WebSphere Application Server(s).
• Configure the WebSphere WSGW inbound and outbound services successfully without WS-Security configuration using HTTP transport.

See Resources for help with these prerequisites.
