Issue/Introduction

You need to add or change parameters in Java LiveUpdate 3.6 or higher and are seeking a way to do so.
For example, you may need to configure JLU to download content updates through a proxy server.

 

Resolution

The Configuration Editor is a new feature introduced in Java LiveUpdate 3.5.
In order to edit values in the encrypted configuration file, Java LiveUpdate 3.5 (and higher) ships with a configuration editor that can be invoked as follows:

java –classpath jlu.jar ConfigEditor

example on Windows:

> Java -classpath "C:\Program Files\Common Files\Symantec Shared\Java LiveUpdate\jlu.jar" ConfigEditor
 

If you use a 64bit OS the classpath is below:

java -classpath "C:\Program Files (x86)\Common Files\Symantec Shared\Java LiveUpdate\jlu.jar" ConfigEditor

 

The above command opens a GUI that can be used to edit all values of existing properties and also add or delete properties in it:



Important:
If you select to save the file in encrypted format and the liveupdate.conf resulting file is 0Kb, it means that you are not using the correct JCE policy files for your Java Runtime Environment.
