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
