To be able to copy and paste data from outside of the applet
you need to grant permissions to the java applet.
To set permissions, you need to edit the java.policy file.
You can find the java.policy at:
lib\security\java.policy
The actual location of java.policy depends on your operating system.
Below are example locations on Linux and Windows:
Linux:
/usr/local/java1.4/jre/lib/security/java.policy
Windows:
C:\\Program Files\Javaj2re1.4.1_03\lib\security\java.policy
You may have multiple JRE's installed, make sure all your changes are made
to the JRE your web brower is using.
Edit java.policy so it contains the following:
[replace your.rib.server.hostname with your actual name]
grant codeBase "http://your.rib.server.hostname/java/-"
{
permission java.security.AllPermission;
};
