This step of the tutorial instructs how to download a Java-Archive (JAR) with the base-classes for Fat-Client-development and incorporating the file into the 'Build-Path' of the project for the Fat-Client.

`Preface:`

This step has to be done, if you want to use the Java-Archive with the base-classes and not code the base-classes during the tutorial.

As an alternative you may take more practical exercise and implement the code for the base-classes manually. This is described in the document JS_FC01ca - Create a project for the base-classes.

`Credits:`

To many to list – but I compiled this document and (hopefully) made the procedure easier to understand ;-) .

Prerequisites:

JS_FC01b - Create a new workspace and a project in Eclipse completed – and its prerequisites too.

`Preparation:`

There a two files with a Java-Archive for the base-classes available: * A smaller one with just the *.class files (precompiled code) that is named 'JSBS.jar'. All further examples refer to this file. * Another file also includes the source-code. That file is named 'JSBS_With_Source.jar'. It includes the *.class files (precompiled code) too; therefore it can also be incorporated into the 'Java Build Path' later. Depending on the folder under which 'JSBS.jar' or 'JSBS_With_Source.jar' should be stored, your user rights may not be sufficient. If you experience problems during saving the file either do the download with 'root'-rights or save to a folder you are allowed to save.

Download the 'JSBS.jar' archive or the 'JSBS_With_Source.jar' archive. Choose the 'Save to Disk' option and select a directory. N.B.: On my newest version of the 'Mozilla'-browser the file is saved to the 'Desktop'-directory of the users-home. (e.g.: /home/kurti/Desktop). In that case please pick it up from there and move it to the final directory. I used the directory '/usr/java/j2sdk1.4.2_08/lib/extern' - and will refer to it in further steps.
Now it is time to incorporate the file into the libraries. Mark the project 'JS_FC01', right click with the mouse and select >Properties.
On the window that just openend select 'Java Build Path' (on the left side) and the tab 'Libraries'. Then click the button [ Add External JARs... ].
Manouvre to the directory '/usr/java/j2sdk1.4.2_08/lib/extern' and select the file 'JSBS.jar'. Then click the button [ OK ]. The incorporation of the selected JAR-file into the Java Build Path is shown. Click the button [ OK ].

`Next Step:`

A simple GUI is created: JS_FC01d - Create and code the class for the GUI.
