JCreator User Manual

Installing the jpb Package

The textbook author has written three classes used to simplify console I/O, conversions, and graphics. If you decide to work with JCreator at home, you will need to download the jpb package (Java Programming from the Beginning) on your home computer to use these classes.

  1. Right-click jpb.zip package and select Save Target As ... to download and save jpb.zip to your desktop.
  2. Right-click the downloaded jbp.zip folder on your desktop and select Extract All ... to use the Windows XP extraction wizard to extract the folder and its contents to your desktop.
  3. As the extraction wizard completes, click to open the jbp folder
  4. Copy the extracted jpb folder with its contents (four class files) to
    C:\j2sdk1.4.2_05\jre\lib\ext\ folder
    • Caution: do not copy the jpb folder directly on the desktop. Click to open this folder and you should see another jpb folder nested inside it. This inner jpb folder is the one you want to copy.
    • The jpb folder contains four files: Convert.class, SimpleIO.class, DrawableFrame.class, and DrawableFrame$WindowCloser.class.
  5. Add the path to the jpb package in your JCreator profile. Follow the instructions for configuring the JDK Profile as you did in lab.
  6. You may now safely delete the jpb folders on your desktop (both the zipped folder and the extracted folder)
