Copy the two .jar files ( wnonstandard.jar and wutil.jar ) that are in
http://www.rose-hulman.edu/class/cs/csse220/200820/web/Resources/Code_and_docs_Weiss_book/
into your C:\Program Files\Java\jdk1.6.0\jre\lib\ext folder.
Look in that folder to see that they are there. For some
mysterious reason, you web browser may want to change the extension
from jar to zip when it downloads the files. If so, change the
extensions back to .jar
While you are there, you may also want to copy the code.tar
and docs.tar files from the textbook-files folder, and unpack
them (using WinZIP or WINRAR) to wherever you are putting your CSSE
220 materials. These files will be useful in understanding code
that is in the textbook, since they should enable you to experiment
with that code
