[Kde-java] Problems executing a shell-script in the alt+f2-dialog

[Kay Patzwald]

Hi,

I have a problem with a shellscript (in /usr/bin). The script starts a  
java-program (in /usr/share/tvbrowser). I hope this is is correct  
mailing-list.
When I execute the script from kmenu (I create an entry) or the shell the  
program starts normal, but when I execeute the script from the  
alt+f2-dialog (in German "Befehl ausführen") the program starts in  
background and the dialog don't disappear. After quitting the program, I  
get an error-dialog: "KDEInit kann tvbrowser nicht starten" (Sorry, I  
don't know the english error-message, maybe: "KDEInit cannot execute  
tvbrowser").

Best regards,
Kay

The script:

#!/bin/bash

# Based on Start-Script provided by Azureus

JAVA_PROGRAM_DIR=""	# use full path to java bin dir, ex.  
"/usr/java/j2sdk1.4.2/bin/"
PROGRAM_DIR="/usr/share/tvbrowser"		# use full path to TV-Browser bin dir
