A target system can have multiple services associated with it. A URL must be defined for every service associated with a remote system. The URL is used for identifying and interacting with the service in the remote system. The URL is based on the combination of the root URL of the remote system, consisting of the system host name and port, and the extension URL for the associated service. For example, a URL http://shell:9082/ProcessApplicationService for a process application web service on a remote system is the combination of the root URL(http:// shell:9082/) of the remote system and the extension URL(ProcessApplicationService) of the associated process application service. The Invoking User Name and Password define the user name and password required to communicate with the web service on the remote system.
