Tomcat turn off directly after startup when called using gksu

Question

I'm trying to use a launcher within the gnome menu in order to start a Tomcat server. For that I used the following command "gksu sh /myhome/tomcat_starter". The script "tomcat_starter" defines some environment variables before it starts the server:

#!/bin/bash

JAVA_HOME="/myhome/java" 
export JAVA_HOME
PATH=$PATH:$JAVA_HOME/bin
export PATH

CATALINA_HOME="/myhome/tomcat"
export CATALINA_HOME

$CATALINA_HOME/bin/startup.sh

When the launcher started, it asks for the su password as expected and also started the tomcat server. But the server turns off directly after the start.

Here is a cuttout from the log file

Does someone has an idea why the tomcat server turns off ?

Answer 1

I find out that by using the command "nohup" the server will remain running in the background. So the launcher command is now "nohup gksu sh /myhome/tomcat_starter" and it works well.
