Server information
Notice in the examples that the server version number is required as part of the URL for the Authentication, Administration, Expression, and Function services.
To retrieve the version of the server, use the Public service function ServerVersion:
http://servername:port/service_name/api/public/ServerVersion
This call displays the version in XML, as the following example shows:
<value>v8</value>
