Setting up DrJava at Home (Mac)

If you are using a Mac at home and you would like to install DrJava, you should follow these instructions. Note: you must be running Mac OS X v10.4 (Tiger) in order to use Java 1.5 (some parts of CS133 require the use of Java 1.5).

Installing Java 1.5

1 Go to this Apple web page and click on the down arrow around the right side of the page to download Java 1.5, and install it.

2 Open Terminal, which is in Applications, in Utilities, which brings you the Unix command line.
3 Change your working directory to the Java Versions directory: type cd /System/Library/Frameworks/JavaVM.framework/Versions at the prompt and hit return.
4 Remove the link CurrentJDK which points to 1.4.2 and replace it with a link pointing to 1.5.0 with these two commands (you will need an administrator password):
sudo rm CurrentJDK
and then
sudo ln -s 1.5.0 CurrentJDK
and then close the terminal.

Installing DrJava
4 On the DrJava homepage, click the Download Mac OS X App button under the heading "Current Stable Release".
5 Select any of the mirrors (it doesn't matter which) by clicking the appropriate icon.
6 Save this file on your computer and install DrJava.

Now follow the Library Instruction page to configure your version of DrJava at home to use the Board and Coordinate classes.
