In order to monitor your remote app with jvisualvm which comes with the jdk
(location /usr/java/jdk1.6.0_30/bin)

first you should run ./jstatd in the remote server and give port like the one below;

./jstatd -p 1111 -J-Djava.security.policy=visualvm.policy

visualvm.policy is a file contains the following lines

grant codebase "file:${java.home}/../lib/tools.jar" {
     permission java.security.AllPermission;
};
