Installation

This document describes how to install the Core Library software contained in the core package. The following topics can be found in this document:

• System Requirements
• Unpacking the Package

System Requirements

The Core Library software was developed using Java and will run on any platform with a supported Java Runtime Environment (JRE). The software was specifically developed under Java version 1.6 and has only been tested with this version. The following commands test the local Java installation in a UNIX-based environment:

% which java
/usr/bin/java

% 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)
      

The first command above checks whether the java executable is in the environment's path and the second command reports the version. If Java is not installed or the version is not at least 1.6, Java will need to be downloaded and installed in the current environment. Consult the local system administrator for installation of this software. For the do-it-yourself crowd, the Java software can be downloaded from the Oracle Java Download page. The software package of choice is the Java Standard Edition (SE) 6, either the JDK or the JRE package. The JDK package is not necessary to run the software but could be useful if development and compilation of Java software will also occur in the current environment.

Unpacking the Package

Download the core package from the PDS FTP site. The binary distribution is available in identical zip or tar/gzip packages. The installation directory may vary from environment to environment but in UNIX-based environments it is typical to install software packages in the /usr/local directory and in Windows-based environments it is typical to install software packages in the C:\Program Files directory. Unpack the selected binary distribution file with one of the following commands:

% unzip core-1.0.0-bin.zip
or
% tar -xzvf core-1.0.0-bin.tar.gz
      

Note: Depending on the platform, the native version of tar may produce an error when attempting to unpack the distribution file because many of the file paths are greater than 100 characters. If available, the GNU version of tar will resolve this problem. If that is not available or cannot be installed, the zipped package will work just fine in a UNIX environment.

The commands above result in the creation of the core-1.0.0 directory with the following directory structure:

• README.txt
  

  A README file directing the user to the available documentation for the project.

• LICENSE.txt
  

  The copyright notice from the California Institute of Technology detailing the restrictions regarding the use and distribution of this software. Although the license is strictly worded, the software has been classified as Technology and Software Publicly Available (TSPA) and is available for anyone to download and use.

• doc/
  

  This directory contains a local web site with the Core Library documentation, javadoc, unit test results and other configuration management related information. Just point the desired web browser to the index.html file in this directory.

• lib/
  

  This directory contains the dependent jar files for the software along with the jar file (core-1.0.0.jar) containing the Core Library software.

• schema/
  

  This directory contains the latest version of the XML Schema documents as of the release of this software.
