JOSM Tips&tricks

Running JOSM

• Web Start - https://josm.openstreetmap.de/download/josm.jnlp

• Mac OS app - https://josm.openstreetmap.de/download/macosx/josm-macosx.zip

• Finder - If you have downloaded josm-tested.jar (josm-latest.jar) you can start JOSM by clicking on the josm-latest.jar file in the MacOS Finder.

• Terminal - https://josm.openstreetmap.de/wiki/InstallNotes#Running java -jar FOLDER/josm-latest.jar

Supply parameters

• If you need to supply parameters (e.g. -Xmx2048M to run with more Java memory) you can use the MacOS "Terminal":

  java -Xmx512M -jar FOLDER/josm-latest.jar

  This would allow JOSM to use up to 512 MB of RAM (memory). The java option "-Xmx512M" set's the maximum Java heap size to 512 MB. You are free to replace -Xmx512M by any number appropriate for your system (e.g. -Xmx2048M or even more).

• If you are using the Mac OS X Package and want to alter a startup parameter permanently, then you will need to alter the Info.plist file within the /Applications/JOSM.app/Contents directory. For example, to increase the maximum Java heap size from 512MB to 2048MB, either using the terminal or XCode, in the JVMOptions key alter the entry -Xmx512m to -Xmx2048m.

  

• Using Java Control Panel
