Cisco ONS 15327 Troubleshooting Guide, R3.4
April 2003
Chapter 1 General Troubleshooting
CTC Operation Troubleshooting
Procedure: Manually Edit the java.policy File
Step 1 Search your computer for this file and open it with a text editor (Notepad or Wordpad).
Step 2 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 restart Netscape.
CTC should now start correctly.
Step 5 If the error message is still reported, save the java.policy file as “.java.policy.” On Windows 95, 98, and
2000 PCs, save the file to the C:\Windows folder. On Windows NT 4.0 PCs, save the file to all of the
user folders on that PC, for example, C:\Winnt\profiles\joeuser.
1.6.8 Java Runtime Environment Incompatible
Symptom The CTC application does not run properly.
Table 1-15 describes the potential cause of the symptom and the solution.
Table 1-15 Java Runtime Environment Incompatible
Possible Problem Solution
The compatible Java 2
JRE is not installed.
The Java 2 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 15327 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 15327 software CD and on
the Cisco ONS 15327 documentation CD. See the “Launch CTC to Correct
the Core Version Build” procedure on page 1-59.
If you are running multiple CTC software releases on a network, the JRE
installed on the computer must be compatible with all of the releases that you
are running. See Table 1-16 on page 1-59.
