No user-friendly installer is available for the moment. Here are some indications to make JEphem run.
  • As JEphem is developed in java, it needs a java virtual machine (version 1.4 or later) to run.
    If you don't have already one installed on your machine, you can go to Sun's site (http://java.sun.com/j2se/1.4/download.html), download a JRE (Java Runtime Environment), and install it.


  • Then download a zip file containing an executable version of JEphem (cf download area), and unzip it. All the files will be located in a directory named 'JEphem'.


  • Edit the script 'JEphem_run.bat', located in directory JEphem/java, and adapt it to your machine (change the path to the java interpreter). It should be easy both under Linux and Windows. It doesn't use environment variables. If you have a problem, mail me, I'll try to help.


  • You can run JEphem by launching 'JEphem_run.bat'.


  • If you want to also use Swiss ephemeris (which provides computation from DE406), you need to download the files from ftp://ftp.astro.ch/pub/swisseph/ephe/ and copy them to the directory 'JEphem/data/astro/swissEphem'.
