Landmark Manager Live Demo
In order to make this applet running in your web browser you need to grant following java permissions:
grant codebase "https://www.gms-world.net/-"
{
permission java.util.PropertyPermission "user.home","read";
permission java.net.SocketPermission "*", "connect, resolve";
permission java.io.FilePermission "${user.home}/-","read, write";
permission java.util.PropertyPermission "microedition.platform", "read";
};
The easiest way to do that is to create .java.policy file in your home directory and copy/paste grant statement from above.
For more details please refer to Java Policy Files Documentation.
