Java Setup

OpenJUMP can run on Linux, Unix, MacOSX, Microsoft Windows (from 98 to Vista) and any Operation System that supports Java.

OpenJUMP requires:

  • minimum 124 MB to run, better 256 MB (note: if the script files are used for starting, then one can assign less memory using the -Xmx option)
  • At least JRE 1.5 installed.

Some plugins could also require the installation of Java(TM) Advanced Imaging (JAI)) and Java3d

Installing OpenJUMP on Linux

  • 1 - In the Jump Pilot Project download OpenJUMP Platform Indipendent
  • 2 - The platform-independent version of OpenJUMP comes under the form of a compressed archive (ZIP). To install, decompress the archive in your hard drive, for example into c:/OpenJUMP

You will see the following folder structure:

    • c:/OpenJUMP/
    • c:/OpenJUMP/bin
    • c:/OpenJUMP/lib
  • 3 - In the BIN folder there are the statup scripts for Linux/Unix: or There is an improved script for unix:
  • 4 - Eventually, to run OpenJUMP first make the startup script executable. For instance, if you want to use file, open the consolle and write:
chmod +x

Some Linux Distro like Ubuntu and Debian allows to make script executable by "property" window. (+x commmnd makes openjump script executable)

  • 5 - Run Openjump by consolle with this command:

A few notes about Linux installation:

1) The Java version to be run... Linux Distros come with a open-source version of Java. OpenJUMP will use that per default. Should one want to use Sun's Java (recommended) some changes are necessary to the JUMPHOME/bin/ script:


(usually there but distro-dependent -- or wherever you've installed it)

The last line of the script (calling Java) should be like this:

$JAVA_HOME%/java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel -Dlog4j.configuration=file:./log4j.xml -Xms512M -Xmx1024M -cp $CLASSPATH com.vividsolutions.jump.workbench.JUMPWorkbench -properties workbench-properties.xml -plug-in-directory $LIB/ext 

2) Also be sure to correctly specify OpenJUMP's installation folder in JUMPHOME.

Installing OpenJUMP on MacOSX

  • 1 - open a terminal window
  • 2 - move to the "bin" folder (using "ls" and "cd" commands in the terminal)
  • 3 - if you arrived in the bin folder, openjump can be started by typing: "sh" and pressing enter

Installing OpenJUMP on Microsoft Windows

In the Jump Pilot Project it is possible to download two versions of OpenJUMP for windows:

OpenJUMP Win32 installer for Windows

  • Download the OpenJUMP Win32 installer (EXE file). This is a setup file which automatizes the installation
  • Run the file to setup OpenJUMP. The software will be installed in the computer and a new icon "OpenJUMP" will be created in the desktop to launch the program

OpenJUMP (ZIP file)

  • Download the ZIP file and decompress it in a folder (e.g. OPENJUMP)
  • In the folder OPENJUMP/BIN search for the files OpenJUMP.exe or OpenJUMP.bat which are used to launch the software
  • eventually create a shortcut on the desktop for the launcher

OpenJUMP Nightly Build is basically the same version of OpenJUMP (ZIP file). See also OpenJUMP Install Instructions page
