I think your security policy is set too tight.

Which operating system are you using?

[ratnesh31]

Window XP
Please guide me how to change policy setting.

[Kees de Kooter]

A good starting point is the Tomcat Security Manager Howto (http://tomcat.apache.org/tomcat-6.0-doc/security-manager-howto.html).

The easiest way to permit java monitor to work is to add the following lines to your policy file:


grant codeBase "file:${catalina.base}/webapps/java-monitor/-" {
permission java.security.AllPermission;
};

Thanks you very much
its working fine now.

Dear ratnesh31,

Are you behind an HTTP proxy server? If so, check out the "Common Problems and Solutions: HTTP Proxies" section of the installation guide (http://java-monitor.com/install.html) (scroll all the way to the bottom).

If not, is there a firewall blocking outgoing traffic to Java-monitor?

Dear Kees Jan

I have resolved this problem
Yes I was behind pxoxy setting thats why I faced this problem

I have made the changes in JVM arguments.

Thanks.
