Connecting VisualVm with remote host


I need to monitor memory usage of a process running on a remote host with visualvm.I'm following steps as mentioned in http://visualvm.java.net/applications_remote.html.But when starting jstatd i'm having following error

Could not create remote object
access denied (java.util.PropertyPermission java.rmi.server.ignoreSubClasses write)
java.security.AccessControlException: access denied (java.util.PropertyPermission jav
a.rmi.server.ignoreSubClasses write)

at java.lang.System.setProperty(System.java:727)
at sun.tools.jstatd.Jstatd.main(Jstatd.java:122)
