A Java Runtime Environment (JRE), version greater than 1.6, is
required to run Jython and GeoScript. Chances are your system
already has a JRE installed on it. A quick way to test is to
execute the following from the command line: % java -version
java version "1.6.0_26" Java(TM) SE Runtime Environment (build
1.6.0_26-b03-384-10M3425) Java HotSpot(TM) 64-Bit Server VM
(build 20.1-b02-384, mixed mode) If the command is not found or
the Java version is less than 1.6 you must install a new JRE.
Otherwise you can continue to the next step. A JRE can be
downloaded from Sun Microsystems. It is possible to run
GeoScript with a different non Sun JRE. However the Sun JRE is
recommended as it has been thoroughly tested. Jython version
greater than 2.5.1 is required for GeoScript. The current
version can be downloaded from http://www.jython.org/. After
install ensure that the Jython bin directory is on the path:
Where <JYTHON_DIR> is the root Jython installation directory.
