If I try to start up jconsole or jvisualvm I get the following error code:

"enviroment variable “Display” is not set or no x11 Display variable is set.

In what file and with what command do I add this variable.

Configuration:

jdk1.6.016

Linux Debian etc

Wowza 1.7.2

Jwplayer 4.6

I use notepadxml.msi (windows) for editing xml files and this is ok. But if I try to edit files like startup.sh with notepad (windows) it corrupts the file. Does anyone know a good editor for such files on linux.

I really don’t know Debian that well. It sounds like you are not running the X11 window environment. You cannot run JConsole/VisualVM from the command line interface. You need the desktop windowed environment.

On Linux I use vi to edit config files.
