Here is a small tutorial for all who want to install Apache Tomcat on a QNAP.

First of all, download Java and Apache Tomcat and upload on your NAS.

Below are the paths to install Java and Apache Tomcat that I used :

• Java : /share/Qweb/java6
• Tomcat : /share/Qweb/tomcat6

Then, I have created the file tomcat.sh on the root of tomcat6.

#!/bin/sh
#Tomcat self-starting
#Auteur : Cyril GRANDJEAN
#Description : Self-starting de tomcat
#name of the process : tomcat
#pid of  : /var/run/tomcat.pid
RETVAL=0
QPKG_NAME="tomcat6"
_exit()
{
   /bin/echo -e "Error: $*"
   /bin/echo
   exit 1
}

JRE_HOME="/share/Qweb/java6"
CATALINA_HOME="/share/Qweb/tomcat6"

case $1 in
  start)
    sh /share/Qweb/tomcat6/bin/startup.sh
    ;;
  stop)
    sh /share/Qweb/tomcat6/bin/shutdown.sh
    ;;
  restart)
    sh /share/Qweb/tomcat6/bin/shutdown.sh
    sh /share/Qweb/tomcat6/bin/startup.sh
    ;;
  *)
    echo "Usage: $0 {start|stop|restart}"
    exit 1
esac
exit $RETVAL

Then, to use it as a package on the interface of the QNAP, I have used the following commands :
echo "[tomcat6]" >> /etc/config/qpkg.conf
echo "Name = Tomcat6" >> /etc/config/qpkg.conf
echo "Version = 6.0" >> /etc/config/qpkg.conf
echo "Enable = TRUE" >> /etc/config/qpkg.conf
echo "Shell = /share/Qweb/tomcat6/tomcat.sh" >> /etc/config/qpkg.conf
You can now use Apache Tomcat on your QNAP.
