Java – Configuring a Jetty web application on a different port

javajetty

I'm brand new to Jetty.

I'd like to ask if its possible to have Jetty listening on port 8080, however where specified, serve a specific web application under say /var/jetty/webapps/<appname> (default on CentOS) served on say port 10000 instead of http://localhost:8080/<appname> i.e. http://localhost:10000/ = http://localhost:8080/<appname> ?

If so, what configuration changes would be required to make this work without an additional proxy server? I've googled away, but haven't found a solution (perhaps I've missed something obvious?).

You can change the port on a linux deployment using the environment variable JETTY_PORT.

eg:

export JETTY_PORT=20000

Then launch the application.

Configuring Jetty to accept connections from all hosts on Ubuntu Lucid

Found it! You need: -

JETTY_HOST=0.0.0.0

to listen to other hosts. So a minimal /etc/default/jetty file includes: -

JAVA_HOME=/usr/lib/jvm/java-1.5.0-sun
NO_START=0
JETTY_HOST=0.0.0.0
JETTY_PORT=8080

Linux – Deploy Jetty as port 80 daemon on Linux

Unfortunately, Java processes tend not to daemonize as well as other languages. For Jetty, you'll want to use something like daemonize to launch and manage the process.

Edit - some additional details:

After building daemonize (as per instructions in above link), the command line parameters are explained in the generated file daemonize.html. Test it out from the launch command to ensure it works as expected.

Then to launch Jetty at startup, add the daemonize command to an init shell script (e.g., for CentOS/RHEL append /etc/rc.d/rc.local). For example:

#!/bin/bash
#...other startup commands

/path-to/daemonize -c /path-to/jetty/ -p pid.txt -e error.log -o console.log -a /usr/bin/java -jar start.jar
