CSSE 230 — Data Structures and Algorithm Analysis

Weiss Package Installation Instructions

  1. These files will be useful in understanding code that is in the textbook, since they should enable you to experiment with that code. You might also want them for some of the programming assignments.
  2. Go to the Weiss-source folder on the course web space. Open code.zip and copy the two .jar files, wnonstandard.jar and wutil.jar, within it into the jdk/jre/lib/ext folder on your laptop. On Windows this will be something like: C:\Program Files\Java\jdk1.7.09\jre\lib\ext
  3. Use Windows Explorer (not Internet Explorer) to look in that folder to see that the jar files are there. Some web browsers change the extension from .jar to .zip when it downloading the files. If yours is so rude, change the extensions back to .jar.
  4. (Optional) While you have your web browser open to the Weiss-source folder, you may also want to copy the code.zip (source code) and docs.zip (javadoc) files from the textbook-files folder, and unpack them (using WinZIP or WinRAR) to wherever you are putting your CSSE 230 materials.
  5. In Eclipse, choose the project that you want to add Weiss' libraries to , then select Build Path > Add External Archives ... and browse to where you stored the jar files. Select wutil.jar and wnonstandard.jar. 
  6. Your project should now be able to use Weiss code. 
  7. Alternatively, if you want to modify the JDK so every project uses Weiss' code, you can choose Window > Preferences > Java > Installed JREs. Select jre7 (or 8) and choose Edit.. In the next window, choose Add External JARs and browse to and select wutil.jar and wnonstandard.jar.
