HOWTO: Upgrade Tomcat in Nuxeo 8.10 on Windows?

Updated: March 18, 2024

As a prerequisite, the machine on which you will upgrade Tomcat using this procedure must have an internet access.

To upgrade Tomcat 7.0.69, delivered with Nuxeo 8.10 installers, to a later revision you need to:

  1. Install Cygwin minimal setup including bash, cp, mv, mktemp, sed, grep, cut, rm , mkdir, Curl, Wget, Perl…
  2. Have a recent JDK 8 for Windows 64 bits already installed
  3. Finally, upgrade Tomcat

How to Install the Required Cygwin Minimal Setup on Windows?

Cygwin bash is the preferred bash environment to run bash script for Nuxeo.

Download Cygwin setup program from Cygwin official site: https://www.cygwin.com/, e.g. using the Cygwin setupx86_64.exe installer.

Launch the setup script, choose a way to install it (from internet or another way if you need to), choose the local directory in which you will install Cygwin, choose a mirror site near your location and then choose to install at least the following bundles:

  • Base
  • Perl
  • Wget utility from the Web bundle
  • Curl utility from the Net bundle

You can then accept the software dependencies and install the Cygwin tools and utilities.

How to Upgrade Tomcat?

Download the script directly from this link and save it as c:\temp\upgrade_tomcat7.sh

Assuming you have:

  • The upgrade bash script upgrade_tomcat7.sh on your Windows machine as c:\temp\upgrade_tomcat7.sh
  • Cygwin installed under c:\cygwin64
  • JDK installed as c:\jdk1.8.0_144
  • Nuxeo 8.10 version installed as c:\nuxeo-server-8.10-tomcat

Launch Cygwin bash, then:

export PATH=/cygdrive/c/cygwin64/bin:$PATH
export PATH=/cygdrive/c/jdk1.8.0_144/bin:$PATH
cd /cygdrive/c/nuxeo-server-8.10-tomcat
cp /cygdrive/c/temp/upgrade_tomcat7.sh .
# NOTICE THAT THE FOLLOWING USES A WINDOWS-like PATH SYNTAX with / instead of \ (not a Cygwin path syntax)
./upgrade_tomcat7.sh c:/nuxeo-server-8.10-tomcat
rm ./upgrade_tomcat7.sh
