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 Receiver type the following:
grant codeBase "http://192.168.1.200/"
{
permission java.security.AllPermission "*", "*";
};
This file should have the IP address of the Receiver; 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 Receiver is being monitored from the same computer, it is necessary to
repeat the above for each of the Receivers in the same "java_policy.txt" file.
If DHCP/DNS is enabled, the unique Receiver’s name using DNS should replace the IP
address. Example: "http:\\zSvrTEST". Make sure the DHCP server updates the DNS
table to keep track of the Receiver’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.txt file into the "0_JAVAPOLICY" folder.
