1Supplemental information for JOSM -- the Java OpenStreetMap Editor
4 I. Install & Launch
7Installation notes
9To run JOSM, you need:
11* The JOSM .jar file, e.g., josm-tested.jar or josm-latest.jar
12* Java Runtime Environment (JRE) 1.6, or later.
15How to get Java Runtime Environment
17You need JRE Version 1.6 (also called Java 6), or later.
19Microsoft Windows users should visit
20and download the latest Java executable for Windows systems.
22Linux users should visit
23There is a Linux binary installer, which you must execute from a console, or
24use the mechanism of your distribution's packaging system.
27How to launch
29Microsoft Windows users launch by double-clicking on the .jar file.
30If this does not work, open a command shell and type
31"java -jar josm-latest.jar" in the directory that holds the file. (Please
32replace josm-latest.jar with the name of your .jar file, if you aren't using
33the latest version.)
35Under Linux, open a shell, go to the file directory and type
36"java -jar josm-latest.jar" to launch. If this does not work, try to set
37your JAVA_HOME variable to the java executable location (the root location,
38not the bin).
40MacOS X users just click on the .jar file icon.
43 II. Development
46How to get the source code
48Download it directly from the subversion at
49 To use the command line subversion
50client, type
52svn co josm
55Files & directories
57This is an overview of the files and directories in the JOSM code repository:
58- build.xml ant build file (standard way to create a JOSM binary)
59- CONTRIBUTION list of major code contributors
60- data/ data files that will be included in the JOSM jar file
61 - *.gsb NTv2 grid files for projection support
62 - *.lang translation data
63 - *.xsd xml schema files for validation of configuration files
64 - epsg list of projection definitions
65 - help-browser.css CSS file for the help sites (HTML content is downloaded from the website
66 on demand, but displayed inside the programm in a Java web browser component.)
67 - ignoretags.cfg, tagchecker.cfg
68 data files used by the JOSM validator feature
69- data_nodist/ data files that are useful for development, but not distributed
70 - exif-direction-example.jpg
71 sample image, that contains direction information in the EXIF header
72 (keys: Exif.GPSInfo.GPSImgDirectionRef, Exif.GPSInfo.GPSImgDirection)
73 - filterTests.osm used for unit testing of the filter feature
74 (see test/unit/org/openstreetmap/josm/data/osm/
75 - Join_Areas_Tests.osm some examples to test the 'join areas' feature
76 - mapcss/ sample map styles and corresponding data files for regression testing
77 - projection-reference-data.csv
78 reference data for projection tests
79 (see test/unit/org/openstreetmap/josm/data/projection/
80 - projection-regression-test-data.csv
81 regression data for projection tests
82 (see test/unit/org/openstreetmap/josm/data/projection/
83- tool, to find all used icons and allows deleting unused icons
84- gpl-2.0.txt, gpl-3.0.txt full text of the GNU General Public License
85- images/ images distributed with the JOSM binary
86 - icons images for the Potlatch 2 style

88- images_nodist/ images, which are not for distribution, but may be useful later (e.g. high
89 resolution and vector versions)
90- josm.jnlp Java Web Start launcher file (used on the website)
91- lib/ libraries (directory is empty at the moment)
92- LICENSE the JOSM license terms
93- macosx/ files needed to create the MacOS package

95- optimize-images short script to decrease size of PNG images
96- patches/ patches for external libraries used in JOSM (see below)
97- README this file

106 - unit/ unit tests (source code)
107- tools/ libraries and tools that help in the development process
108 - animal-sniffer-ant-tasks-1.7.jar
109 TODO: what is this?
110 - findbugs/ libs and config files for findbugs (automatically detects common bugs and potential
111 problems in source code); can be launched as an ant target in build.xml
112 - javacc.jar used in the build process to generate some .java files from a javacc source file
113 (src/org/openstreetmap/josm/gui/mappaint/mapcss/MapCSSParser.jj)
114 - proguard.jar optimize final binary jar - see build.xml (not used in production so far)
116The 'patches' directory
118Some libraries that JOSM depends on, are patched for various reasons. The files in the patches directory can be used to roll back these customizations. This is useful in order to
120 * inspect the changes
121 * update to a newer version of the library but keep the modifications
123You can use 'quilt' to manage the patches. E.g. the following command applies all of them:
125 $ quilt push -a
127Of course, it is also possible to apply the patch files manually one by one.
129Third party libraries
131There are a couple of third party libraries which are directly included in the source code tree, in particular:
