i-jetty Instructions

New versions of i-jetty can be downloaded from the Android Marketplace.

From version 3.0 onwards, a web application that exposes your phone information via the network - called the "Console WebApp" - is also available for download via the Android Marketplace.

Building from Source


  • git
  • Java 1.6
  • Maven

Checkout source

Check out the project from

$ git clone

Source structure

The checkout will produce a directory structure like so:

  • i-jetty

    • i-jetty-server : adaptation of Jetty to Android
    • i-jetty-ui : Android app bundle for Jetty
  • console

    • webapp : webapp for controlling phone remotely
    • apk : Android app bundle for installing webapp
  • example-webapps : example webapps integrated with Android APIs


  1. cd i-jetty-read-only/i-jetty
  2. mvn clean install

This produces an adroid app bundle in i-jetty-ui/target/i-jetty-xxxxx.apk. This apk file can then be installed to the phone or to an emulator. For help on installing apk bundles to the phone or the emulator, see

Using i-jetty

Starting i-jetty

Navigate to the "Manage Jetty" application and click on it to activate. Click on the "Start Jetty" button.

Stopping i-jetty

If you already have i-jetty running, you can click and drag down the i-jetty icon in the navigation bar at the top of the screen to see the "Manage Jetty" task. Click on the task.

Now click on the "Stop Jetty" button.

Configuring i-jetty

Click on the "Configure" button to change the settings for i-jetty.

Currently supported settings are:

HTTP Connector Settings

  • Use NIO [true|false]
  • Non SSL Port [8080] HTTPS Connector Settings
  • Use SSL [false|true]
  • Use NIO [true|false] *** only on Android 2.2 and greater
  • Keystore Password [jetty default value]
  • Keystore Filename [/sdcard/etc/keystore]
  • Password [jetty default value]
  • Truststore Password [jetty default value]
  • Truststore Filename [/sdcard/etc/keystore]

HTTP Connector Settings

You can choose to use either an NIO (SslSelectChannelConnector) or a BIO (SocketConnector) based connector. For information on the differences between these connectors, see

NIO is the Default.

HTTPS Connector Settings

An SSL connector will not be started by default. If you wish to use SSL, check the Use SSL checkbox. You will not need to configure anything else, as i-jetty will use its own preconfigured keystore and password settings. If you wish to use your own keystore, then provide the location of the keystore file and passwords as appropriate. You may find it helpful to refer to the Jetty documentation on the SSL connector at

If you are running on Android 2.2 or greater, you also have the option to use an NIO SSL connector. Prior releases use a BIO SSL connector.

Downloading new webapps

Click on the "Download" button and then enter the http url of a android-enabled webapp. The webapp will be downloaded and installed to i-jetty.

You may need to restart i-jetty in order to start the newly installed webapp.
