Download the file ``jhepwork-[version].zip'' from ([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 a JAVA virtual machine is installed. The program can run only with the version 1.5 and above (not JRE 1.4.X!). If you plan to run java code which has to be compiled, you should install the JDK (which includes ``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 JRE (Java Runtime Environment) from the SUN web page SUN web pagehttp://www.java.com/en/download/manual.jsp.
For Linux, one can put ``jhepwork.sh'' to the "$HOME/bin'' directory, so one can start jHepWork from any place. In this case, you should set the variable ``JEHEP_HOME'' (inside the script ``jhepwork.sh'') to the installation directory, i.e. where jehep.jar file is located.
