4.3.4 Java Policy

To activate data logging and save graphs from the Java applets, it is necessary to create

a Java Policy file and copy it onto a folder.

1) Open a Notepad file and using the IP address of the Coordinator type the following:

grant codeBase “http://192.168.1.200/*”

{

Permission java.security.AllPermission “*”, “*”;

};

This file should have the IP address of the Coordinator; in this case the default

IP address is 192.168.1.200. If the IP address is changed, then the IP address

shown in the file needs to be changed; otherwise, it will not work. If more than

one Coordinator is being monitored from the same computer, it is necessary to

repeat the above for each of the Coordinators in the same “java_policy.txt” file.

If DHCP/DNS is enabled, the unique Coordinator’s name using DNS should replace the

IP address. Example: “http:\\zServer_TEST”. Make sure the DHCP server updates the

DNS table to keep track of the Coordinator’s name and IP addresses (consult with your

network administrator).

2) Save the file as java_policy.txt.

3) Create a folder in your C: drive called “0_JAVAPOLICY”.

4) Place the java.policy.policy file into the “0_JAVAPOLICY” folder.
