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 1-15describes the potential cause of the symptom and the solution.

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.
