-/**
- * Servlet that provides information about the presence status of the users in the system.
- * The information may be provided in XML format or in graphical mode. Use the <b>type</b>
- * parameter to specify the type of information to get. Possible values are <b>img</b> and
- * <b>xml</b>. If no type was defined then an image representation is assumed.<p>
- * <p/>
- * The request <b>MUST</b> include the <b>username</b> parameter. This parameter will be used
- * to locate the local user in the server. If this parameter is missing from the request then
- * an error will be logged and nothing will be returned.
