To use the JPT framework with Eclipse, you'll need to follow the following procedure:

http://www.ccs.neu.edu/home/vkp/csu213-sp05/Assignments/Assignment9/edu.neu.ccs.zip

* Download the jpt.zip file and extract it, so that you have a file named "jpt.jar." Store this file with the other files you have downloaded for your homework.

* Start Eclipse. Create a new Java Project that will contain your homework, and import the other homework files normally. You should have a default package.

* With the default package highlighted, go to the Project menu and select Properties.

* In the pane that pops up, select Java Build Path from the options on the left.

* On the right, select the tab named Libraries. Within this tab, click on the button "Add External JARs." Navigate to where you stored your JPT.jar file. Click Ok to leave this window.

* You should now be able to run your homework. The JPT will pop up an interactive framework you can use to explore your program as you modify it.
