  • Which version should I use? (see also: release system)
    • tested is released approx. monthly and shouldn't contain severe bugs
    • latest is released daily, may have more errors
    • If possible, use the Web Start version in order to automatically update.
  • Verify josm.jar with jarsigner

  • Note that there are fairly regular updates, so always try running a recent version (and also recent plugins).
  • Access JOSM-WebStart without installation
  • Download the tested JOSM version 7287
  • Download the Windows JOSM installer version 7287
  • Download the Mac OS X JOSM package version 7287
  • Prepare a USB flash drive to use JOSM on any foreign Windows machine.
  • For download scripts use version check for latest and tested (or both) to reduce download bandwith
  • If download size is an issue you may append ‘?lang=…’ to the download link address for both releases to strip unused translations (e.g. ‘?lang=de’ will download JOSM in German language only).
    • Note: Use underscore to separate language codes with country code extensions, e.g. ‘?lang=en_GB’

Mac OS X Mountain Lion Errors

OS X "gatekeeper" results in this very misleading error dialog

This misleading error message may appear: JOSM.app is damaged and can't be opened. You should move it to the Trash.

To complete the install enter OS X Preferences, visit 'Security & Privacy', and change the settings to allow downloads from 'anywhere'.

After JOSM runs the first time you can return the setting to the original position.

Development Version

  • Download the latest JOSM version 7328 (may have more errors than "tested", be careful with this one).

Source

  • Get the source:
    • From the official Subversion repository (recommended):
      svn co https://josm.openstreetmap.de/svn/trunk
      
    • From the official OSM Subversion repository (including plugins):
      svn co http://svn.openstreetmap.org/applications/editors/josm josm
      
    • From the unofficial GitHub mirror:
      git clone git://github.com/openstreetmap/josm.git
      

Ubuntu repository

The repository for Ubuntu contains two packages:

josm
The tested version
Replaces the package from the official Ubuntu repository.
josm-latest
The development version (nightly build)
Can be installed parallel to the josm package. The default preference folder is ~/.josm-latest.

Installation

Edit the package resource list /etc/apt/sources.list:

sudo editor /etc/apt/sources.list

and add one of the following lines according to your Ubuntu-Version:

deb http://josm.openstreetmap.de/apt lucid universe
deb http://josm.openstreetmap.de/apt natty universe
deb http://josm.openstreetmap.de/apt oneiric universe
deb http://josm.openstreetmap.de/apt precise universe
deb http://josm.openstreetmap.de/apt quantal universe
deb http://josm.openstreetmap.de/apt raring universe
deb http://josm.openstreetmap.de/apt saucy universe
deb http://josm.openstreetmap.de/apt trusty universe

Note: Simply run lsb_release -c in a terminal to get the proper codename.

Download and register the public key:

wget -q https://josm.openstreetmap.de/josm-apt.key -O- | sudo apt-key add -

Now refresh your sources

sudo apt-get update

and install:

josm
(You can skip the first line if you haven't installed these packages before.)

sudo apt-get remove josm josm-plugins
sudo apt-get install josm
josm-latest
sudo apt-get install josm-latest

useful options

If JOSM runs out of memory, you can increase the maximum size of allocated memory (400 MB in this example):

JAVA_OPTS="-Xmx400M" josm

Start with a different preference folder:

JAVA_OPTS="-Djosm.home=$HOME/.josm-tmp" josm

VM selection on Windows x64

For Windows, beware that some browsers may install their own JRE only in 32 bit mode, but may also install their version of the Javawebstart tool somewhere else with different file associations. This may cause your JNLP to start with this alternate JRE because it runs the wrong version of Javawebstart which only supports the 32 bit VM, and sometimes is built with a restricted support for VM options and a max VM size not exceeding 256MB.

Check, for example, if there's no other javawebstart in \Windows\SysWow64. You should not need it (the Java control panel will not detect it) and can safely delete it. Perfom cleanup and only keep the latest version of the JRE (1 for the 32-bit mode, another one for the 64-bit mode).

For shortcuts created on the desktop for JNLP and running the Javawebstart launcher (from \windows\system32), make sure to pass VM parameters prefixed with -J and no intermediate space before the VM option. If you have installed both the 32-bit and 64-bit version, you should pass the option "-d64" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!)

Example of an edited commandline for the shortcut created on the windows desktop after running JOSM just once from the JNMP and exiting:

C:\Windows\System32\javaws.exe -J-d64 -Xmx=2048m -localfile -J-Djnlp.application.href=http://josm.openstreetmap.de/download/josm.jnlp "C:\Users\<snipped user name>\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\21\7311<snipped-hex-number>7f8"

You don't need to change the end of the command line with the snipped parts here. Just check the path for javaws.exe and add options -J-d64 for the 64-bit mode needed to work with large OSM datasets, and -Xmx=2048m to increase the VM size (to 2GB here).
