Chapter 2 General Troubleshooting
2.3.5 CTC Cannot Launch Due to Applet Security Restrictions
If the error message “Unable to launch CTC due to applet security restrictions” appears after you enter
the IP address in the browser window:
Step 1 Verify that you have executed the javapolicyinstall.bat file on the ONS 15454 software CD. This file is
installed when you run the CTC Setup Wizard (see the software installation information in the Cisco
ONS 15454 Installation and Operations Guide for instructions).
Step 2 If you ran the BAT file but still receive the error message, you must manually edit the java.policy file on
your computer. Search your computer for this file and open it with a text editor (Notepad or Wordpad).
Verify that the end of this file has the following lines:
// Insert this into the system-wide or a per-user java.policy file.
// DO NOT OVERWRITE THE SYSTEM-WIDE POLICY FILE--ADD THESE LINES!
grant codeBase "http://*/fs/LAUNCHER.jar" {
permission java.security.AllPermission;
};
Step 3 If these five lines are not in the file, enter them manually.
Step 4 Save the file and re-start Netscape.
CTC should now start correctly.
Step 5 If the error message is still reported, save the java.policy file as .java.policy. On Win95/98/2000 PCs,
save the file to the C:\Windows folder. On WinNT4.0 PCs, save the file to all of the user folders on that
PC, for example, C:\Winnt\profiles\joeuser.
2.3.6 Java Runtime Environment Incompatible
The Java® 2 Runtime Environment (JRE) contains the Java virtual machine, runtime class libraries, and
Java application launcher that are necessary to run programs written in the Java programming language.
The ONS 15454 CTC is a Java application. A Java application, unlike an applet, cannot rely completely
on a web browser for installation and runtime services. When you run an application written in the Java
programming language, you need the correct JRE installed. The correct JRE for each CTC software
release is included on the Cisco ONS 15454 software CD and on the Cisco ONS 15454 documentation
CD.
If you are running multiple CTC software releases on a network, the JRE installed on the computer must
be compatible with the different software releases. Table 2-2 shows JRE compatibility with ONS
software releases.
