1.3 Installation

Download the file jhepwork-[version].zip from:



http://www.hepforge.org/downloads/jhepwork



([version] denotes the current jHepWork version). Then unzip this file, i.e. unzip [version].tar.gz. This creates the directory jhepwork. jHepWork is ready! Run the script jhepwork.sh for Linux/Unix or jhepwork.bat for Windows. Make sure that the Java Runtime Environment (JRE) is installed. The program can run only with the version 1.5 and above (not JRE 1.4.X!). If you plan to run a Java code which has to be compiled, one should install Java SE Development Kit (JDK) which includes the javac compiler.

Check Java by typing java -version . If Java is installed, you should see

java version "1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)
or a similar message. If not, install the recent Java JDK from the SUN web page [8].

For Linux/UNIX, one can put jhepwork.sh to the $HOME/bin directory, so one can start jHepWork from any directory. In this case, one should set the variable JEHEP_HOME (defined inside the script jhepwork.sh) to the installation directory path where the file jehep.jar is located.
