Step 1: Configure the Credential Mapper Servlet (CMS).

We recommend using a J2EE-compliant Web application server such as IBM WebSphere Application Server to configure and deploy the Credential Mapper Servlet (CMS). The CMS is supplied with Z and I Emulator for Web and must be deployed to a J2EE-compliant Web application server. At a high level, the CMS is responsible for the following tasks: (1) determine the client's identity by means of the local system ID, network ID, or Portal ID, (2) map the user's ID to the host ID, and (3) return the host credentials to the client as an XML document.
