I just installed Jetty 6.1.18 on my raspberry pi via apt-get but I have trouble running it.

It works fine when using the start.jar directly (in /usr/share/jetty) with sudo java -jar start.jar, so I can see the "welcome to Jetty" html page when pointing a browser to my pi's IP address

But if it doesn't work if I start it using sudo /etc/init.d/jetty start although the output is:

[....] Starting Jetty servlet engine.: jetty Rotate logs[....] Jetty servlet engine started, reachable on http://raspberrypi:8080/.: jetty.

so no apparent warnings or problems...

Using OpenJDK as JVM, output of echo $JAVA_HOME is /usr/lib/jvm/java-1.6.0-openjdk-armhf

and I edited /etc/default/jetty to reflect $JAVA_HOME there

Has anybody seen a similar issue with jetty or other webservers? Obviously, I'd like the init.d script to work, so that the webserver is up and running at startup automatically...

For info, here is the actual /etc/init.d/jetty script:

#!/bin/sh -e

# /etc/init.d/jetty -- startup script for jetty 6.1.18

### BEGIN INIT INFO
# Provides:          jetty
# Required-Start:    $local_fs $remote_fs $network
# Required-Stop:     $local_fs $remote_fs $network
# Should-Start:      $named
# Should-Stop:       $named
# Default-Start:     2 3 4 5

# Short-Description: Start Jetty
# Description:       Start Jetty HTTP server and servlet container.
### END INIT INFO

# Configuration files
#
# /etc/default/jetty
#   If it exists, this is read at the start of script. It may perform any 
#   sequence of shell commands, like setting relevant environment variables.
#
# /etc/jetty/jetty.conf
#   If found, the file will be used as this script's configuration. 
#   Each line in the file may contain:
#     - A comment denoted by the pound (#) sign as first non-blank character.
#     - The path to a regular file, which will be passed to jetty as a 
#       config.xml file.
#     - The path to a directory. Each *.xml file in the directory will be
#       passed to jetty as a config.xml file.
#
#   The files will be checked for existence before being passed to jetty.
#
# /etc/jetty/jetty.xml
#   If found, used as this script's configuration file, but only if
#   /etc/jetty/jetty.conf was not present. See above.
#   
# Configuration variables (to define in /etc/default/jetty)
#
# JAVA_HOME  
#   Home of Java installation. 
#
# JAVA_OPTIONS
#   Extra options to pass to the JVM
#
# JETTY_PORT
#   Override the default port for Jetty servers. If not set then 8080
#   will be used. The java system property "jetty.port" will be set to 
#   this value for use in configure.xml files. For example, the following 
#   idiom is widely used in the demo config files to respect this property 
#   in Listener configuration elements:
#
#    <Set name="Port"><SystemProperty name="jetty.port" default="8080"/></Set>
#
# JETTY_ARGS
#   The default arguments to pass to jetty.
#
# JETTY_USER
#   if set, then used as a username to run the server as

    What Java are you using? Does sudo /etc/init.d/jetty start output anything? I don't have jetty installed, can you post the contents of /etc/init.d/jetty? Nov 25, 2012 at 4:00

    I take my previous comment back. Jetty is working for me. I was confused over the output of the netstat command which showed tcp6 0 0 :::8080 :::* LISTEN for Jetty's listen. I thought that meant IP V6 only, but it obviously doesn't since it is working for me. I had to edit /etc/default/jetty setting JETTY_HOST to 0.0.0.0 to allow any host to connect.

The default configuration for Jetty in /etc/default/jetty only allows connections from localhost, you need to set JETTY_HOST to 0.0.0.0 to allow Jetty to accept connections from any host.

Add the following line to /etc/default/jetty:

JETTY_HOST 0.0.0.0
