Version 31 (modified by mabapla, 15 years ago) ( diff )

Moved "Getting the source" and "Compiling" to the end. Most users will never want to do this.

Semi-Stable Version

The latest semi-stable version is always here: http://josm.openstreetmap.de/download/josm-tested.jar - we don't call it a "release" because while it is more robust than the nightly build, it doesn't usually run through as many checks as a release would. It is updated approximately once a week.

Nightly Builds

You can always grab the latest nightly build from http://josm.openstreetmap.de/download/josm-latest.jar. Many users actually use this for their daily work.

Running

Microsoft Windows

Double clicking on the jar file.

If this does not help, you probably need to install Java

If you want to be able to handle more points in JOSM you can create a shortcut like the following example:

C:\WINNT\system32\java.exe -jar -Xmx512M "C:\PATH-TO-JOSM\josm-latest.jar"

Linux / *BSD

using the shell
Go to the directory where the josm-latest.jar is and type
java -jar josm-latest.jar
to launch. Replace ''josm-latest.jar'' with the name of the jar file you loaded, e.G. josm.jar for releases.

If this doesn't help, try to set you JAVA_HOME variable to the java location (the root location, not the bin. As example:

 export JAVA_HOME=/usr/lib/sun-j2se5.0-jdk
 java -jar ''josm.jar''
KDE
There is a tutorial on how to setup your environment to start jar-files by clicking on them.
GNOME
Right click on the JAR file, and select Open with "Sun Java 5.0 Runtime", or whatever java version you have.
XGL/Compiz
Type this into a shell:
export AWT_TOOLKIT=MToolkit && java -jar josm-test.jar
as described here: http://kubasik.net/blog/index.php/2006/06/19/java-sun-150-and-xglcompiz-on-ubuntu/

MacOS

1.) If you have downloaded "josm-latest.jar" you can start JOSM by clicking on the josm-latest.jar file in the MacOS Finder (you might get the warning that you are about to open a file from the internet - just accept).

This way to start JOSM should be sufficient in most cases.

2.) However, if you need to start it up with additional Java parameter(s) (e.g. -Xmx512M) you can also use the MacOS "Terminal" and start JOSM (Java) manually:

Start the "Terminal" application (e.g. by typing "Terminal" into the Spotlight search)

Now you have two options:

a.) type in the following command and press "Enter" to start JOSM without any special java options (simply starts up JOSM like under point 1):

java -jar FOLDER/josm-latest.jar

Whereas "FOLDER" should be replaced by the name of the folder you have josm-latest.jar downloaded to. If you have downloaded it to the standard MacOS "Download" Folder it would look like:

java -jar Download/josm-latest.jar

b.) to use additional java options just add them right after "java"

If you for example have experienced the "Out of memory" warning (e.g. trying to load geo-tagged photos to JOSM) you would start JOSM like this:

java -Xmx256M -jar FOLDER/josm-latest.jar

This would allow JOSM to use up to 256 MB of RAM (memory). The java option "-Xmx256M" set's the maximum Java heap size to 265 MB. You are free to replace -Xmx256M by any number appropriate for your system (e.g. -Xmx512M or even -Xmx1024M).

By the way. To get an overview of all Java start options you can type in:

java -help

Getting the Source

JOSM is available under GPL, and so of course you can get the sources and compile, modify or redistribute it by yourself. You can grab the sources via subversion

svn co http://josm.openstreetmap.de/svn/trunk josm

Or you can inspect single files over the web frontend at http://josm.openstreetmap.de/svn.

Compiling

Using ant

The easiest way to compile JOSM provided Java on your machine is properly set up is to go to the josm directory and type:

 ant

That will create a dist/josm-custom.jar file if successful.

Using eclipse

Use eclipse and the provided .project and .classpath file. Just add a new Java Project using the JOSM source folder as existing path.

If you try to compile the JOSM sources in Eclipse and get errors like "The method marktr(String) is undefined for the type SomeType" look at solution suggested at mailing list.

Using javac

You can also build josm without ant or eclipse. To do so, change into the src/ folder and call javac on the file org/openstreetmap/josm/Main with all libs from ../lib/*.jar in your classpath (you have to specify all subsequent). If running linux, be sure to have your JAVA_HOME set.

As example, this could look like:

 $ cd ~/src
 $ svn co http://josm.openstreetmap.de/svn josm
 ''tons of output here''
 $ export JAVA_HOME=/usr/local/jdk1.5.0
 $ cd josm/src
 $ javac -cp .:../lib/MinML2.jar:../lib/metadata-extractor-2.3.1.jar:../lib/gettext-common-0.9.jar org/openstreetmap/josm/gui/MainApplication.java
