Hi all,
I am facing a problem in launching mozilla browser from a program which is running in a service.I have a java program which opens a port and launches the mozilla browser from the terminal or CUI mode. When I run this program through a shell script everything works fine and the browser is easily started but when I tried to run the same program from a service, it opened the port but did not launch the browser.That means the service was running fine but still it could not launch the browser due to some unknown reason. Just to check the things I executed the runmozilla.sh from the service it gave an error as "GTK WARNING : Cannot open display" but the same command ran successfully to launch the browser when I tried it from the terminal.I am working on a Redhat Linux 8.0 and an RHEL 4, I need to create a service or something similar so that the task can be accomplished automatically at boot time or after the GUI is loaded, I am stuck with this therefore pls suggest some solutions.

Thanks

I don't know that I can tell you exactly how to do this, but there are at least two issues here.

First you must set the DISPLAY variable to the display the browser is to use. For example

will display on the first display.

Secondly, (and this is where my knowledge is really shaky) is that the browser is going to have to authenticate to the X server. I have done something perhaps a little in similar in that I have ip-up.local, which is running as root, pop an xterm up on a display. Because of where this was called from, the DISPLAY variable is already set. I then have the script su to the user that owns that display to pop up the xterm. I am not sure if that will be sufficient for you, but hopefully this is enough info to at least get you started.
