2. Installation instructions
----------------------------
Try the shiny installers (for linux & mac)
 OpenJUMP-Installer-*.jar
Or
 Extract the portable zip file distribution.
 OpenJUMP-Portable-*.zip


3. Running OpenJUMP
-------------------
To start OpenJUMP run the launcher for your platform from the 
<appfolder>/bin/ directory.
- On Windows, double-click on oj_windows.bat or OpenJUMP.exe
- On Linux/Unix, launch oj_linux.sh
- On MacOSX, launch oj_mac.command or OpenJUMP.app

Additionally, if you used the installer you should have
- On Windows, a start menu entry.
- On Linux, a link on the desktop.
- On MacOSX, a self contained app on the desktop. 
  Move it to 'Applications' folder if you like.

Further information can be found in the OJ wiki: http://ojwiki.soldin.de


Startup/Command line options
----------------------------
Several startup options are available, either for the Java Virtual Machine, 
or for the OpenJUMP application. To change them, edit the startup script 
accordingly. The scripts contain documentation comments, don't be afraid.

Useful Java VM options
-Xms defines the allocated memory for the virtual machine at startup.
  Example: -Xms256M will allocate 256M of memory for OpenJUMP
-Xmx defines the maximum allocated memory for the virtual machine.
  Example: -Xmx256M
-Dproperty=value set a jvm system property.

OpenJUMP command line syntax:

  oj_starter -option <argument> ... <[data|project]_file>...

OpenJUMP options:

  -default-plugins <file.xml>
    Specifies the configuration file of a standard set of functions realized
    as plugins. For example almost all functions of the "Tools" menu.
    This is configured as
      -default-plugins bin\default-plugins.xml

  -h, -help
    show the help information

  -i18n <locale>
    Overrides the operating systems default locale setting (language, 
    number format etc.) For example:
    - For starting OpenJUMP in French: use -i18n fr
    - languages available (09/2011): 
      cz (czech)
      de (german)
      en (english)
      es (spanish)
      fi (finnish)
      fr (french)
      hu (hungarian)
      it (italian)
      ja_JP (japanese)
      ml (malayalam)
      pt (portuguese)
      pt_BR (brazilian portuguese)
      ta_IN (indian tamil)
      te (telugu)
      zh_CN (chinese simplified)
      zh_HK (chinese Hong Kong)
    ATTENTION: If the specified language is not available then
               the language used is english (en).

  -extensions-directory <path> 
    Sets the location of the extensions folder. Can be defined multiple times.
    Look for extensions in <path>/*.jar files, adds all jar-files recursively
    to runtime classpath. (see also -limit-ext-lookup)
    Default: JUMP_HOME/lib/ext

  -jars-directory <path>
    Adds all contained jar-files recursively to runtime classpath.
    Can be defined multiple times.

  -limit-ext-lookup true|false
    Limits the search for extensions in jar files to jar-files contained in
    extension-directory folder root. Setting to 'false' enables extension
    lookup in all jars + class files recursively (for devel purposes).
    Default: true (to speed up OJ start)

  DEPRECATED: use '-extensions-directory','-jars-directory','-limit-ext-lookup'
  -properties <file.xml>
    specifies the file where OpenJUMP persistent properties are stored.
    See Wiki article "How to use a plugin with a properties file in ECLIPSE".
    Default: JUMP_HOME\bin\workbench-properties.xml

  -state <some/folder>
    specifies the folder where OpenJUMP stores data between executions
    (workbench-state.xml).
    Default: JUMP_HOME or SETTINGS_HOME

  -v, -version
    show version information

5. OpenJUMP history
-------------------
OpenJUMP is a "fork" of the JUMP "Java Unified Mapping Platform" software,
developed by Vividsolutions and released in 2003.
During 2004, some enthusiastic developers joined together to enhance further 
the features of JUMP. They launched an independent development branch called 
OpenJUMP. This name gives credit to the original JUMP development, and at the 
same time describes the objectives of this project to be fully open to anyone
wanting to contribute.
Since May 2005 a complete development source is available at:
www.sourceforge.net/projects/jump-pilot
In 2021, OpenJUMP moves to Github : https://github.com/openjump-gis/openjump
