Turns a WAR file into a DEB file for Tomcat use

wartodeb.sh

#!/bin/bash
#
# WAR to DEB
# This script takes a WAR file, and packages it into a DEB file targetting tomcat's default webapps directory,
# /var/lib/tomcatX/webapps
# Arguments:
# -h    Help text
# -s    Tomcat version (default: 7)
# -p    Custom output path
# -f    Input WAR file
# -v    WAR release version (e.g. 1.0 or 1.0.0)
# Dependencies: dh-make debhelper devscripts fakeroot

This command packages a WAR file into a DEB installer, which is convenient for
feeding into the Netflix AMInator system.

Options:
-h       This help text
-c       Creator e-mail address (required)
-s       Set tomcat version (default: 7)
-p       Override output path entirely (default: /var/lib/tomcatX/webapps)
           Where X is the Tomcat version
-f       The WAR file to operate on
-v       WAR release version (e.g. 1.0 or 1.0.0)

Aptitude dependencies:
           dh-make debhelper devscripts fakeroot

@ukreddy-erwin it looks like there was some whitespace encoding errors in the version I put here. I updated it, try again :)

For me I need to deploy a war file into tomcat server and some other files also manually.
So, used your script and changed ROOT.war entries with my war file name and kept a pause for 5 min before build command so that I copied the files to tmp folder created and also edited control file to add tomcat9 as dependency. But these extra files are not getting copied to the target location during installation. Any suggestions please.

I don't think I have any solutions for you I'm sorry. It's been a few years since I last worked with Tomcat and WAR files.

I'm not sure this script would work for your use-case, if I recall correctly it's only for when you want to deploy a default webapp to a fresh Tomcat installation and overwrite the built-in ROOT webapp that comes with Tomcat.

If you're just trying to deploy a WAR file to Tomcat I don't know if I would even use this script when you can just deploy the WAR file directly.
