1. Java Runtime Environment V 1.3. Eclipse does not include a Java Runtime Environment (JRE), so you will need a 1.3-level Java runtime or Java Development Kit (JDK) installed on your machine in order to run Eclipse. I recommend using the IBM or the Sun JRE/JDK:
   • IBM developer kit (http://www.ibm.com/developerworks/java/jdk/)
   • Sun developer kit (http://java.sun.com/j2se/1.3/download.html)
   
   
2. Eclipse Base V2.1.1. After you read and understand the Eclipse Foundation Software User Agreement, then download the Eclipse base. For this tutorial, we are using the latest release, which is 2.1.1 at the time of writing, but almost any version will do. Download and unzip a copy of the Eclipse base V2.1.1.. Throughout this document we will refer to %ECLIPSE_BASE%, which is the base directory in which you unzipped the Eclipse base V2.1.1.
   
   
3. Eclipse Modeling Framework, V1.1.0, Build 20030620_1105VL. Next, download the Eclipse Modeling Framework component, which we will call EMF throughout this tutorial. For this tutorial, we are using version 1.1.0, Build 20030620_1105VL. You can either download EMF from the EMF Web site or directly download EMF Version 1.1.0 from the following links:
   • EMF Runtime
   • EMF Documentation
   • EMF Source

   After you have downloaded EMF V1.1.0, you should unzip the three zip files into the %ECLIPSE_BASE%\eclipse directory. Make sure that the directories line up so that the EMF plug-ins go into the %ECLIPSE_BASE%\eclipse\plugins directory.

   As an alternative, you can keep these additional components separated from the base by unzipping the three zip files into a subdirectory and then using an Eclipse link file to point to where the additional plug-ins are. Remember that EMF and XML Schema components are just Eclipse plug-ins; they work the same way as any other plug-ins in Eclipse. To keep these other plug-ins separated from the base, you need to create a "links" directory directly under the %ECLIPSE_BASE%\eclipse directory. In the links directory, add a file that contains the following:

   • Filename: org.eclipse.emf.link
   • Contents: path=C:\\Dev\\eclipse\\emf110
     NOTE: Remember that on windows you have to escape the backslashes in this file.

4. XML Schema Infoset Model, V1.1.0, Build 20030620_1105VL. Next, download the XML Schema Infoset component, which we will call XML Schema model throughout this tutorial. For this tutorial, we are using version 1.1.0, Build 20030620_1105VL. You can download XML Schema model from the XML Schema Infoset Model Web site or you can directly download XML Schema model Version 1.1.0 from the following links:
   • XSD Runtime
   • XSD Documentation
   • XSD Source

   After you have downloaded the XML Schema plug-ins, you can do the same thing that you did with the EMF plug-ins. Either unzip them into the %ECLIPSE_BASE%\eclipse directory or point to them using an eclipse link file.

Note: When using the EMF and XML Schema components, remember that the build date and build level for the XML Schema Runtime must match that of the EMF Runtime that you plan use. For example, you could use the XSD Runtime (xsd_1.1.0_20030620_1105VL.zip) with the EMF Runtime (emf_1.1.0_20030620_1105VL.zip), which is what we are using in this tutorial.
