No security manager: RMI class loader disabled

Question

i tried to add a filter to my client jmx
my filter is:
class Filter implements NotificationFilter {
public boolean isNotificationEnabled(Notification n) {
          return (n.getType().equals("example.user.remove"))
          ? true
          : false;
in my client i use:
Filter filter=new Filter();
Listener listener=new Listener();
mbeanServer.addNotificationListener(mbeanName, listener, filter, null);
if i dont put the filter(if i use null) my client works but when i include the filter I have this error:
java.rmi.UnmarshalException: java.lang.ClassNotFoundException: Filter (no security manager: RMI class loader disabled); nested exception is:
     java.lang.ClassNotFoundException: Filter (no security manager: RMI class loader disabled)
what is wrong?

Answer 1

You need to make sure that Filter.class is on your classpath, either directly as the .class file or in a JAR file that is on the classpath.
