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 determining the client's identity and returning the host credentials to the client as an XML document.
