Create a new JCreator project named orderprocessing2005. It will create a new directory. Next, put all of these files into the directory created by JCreator. You can put the junit stuff there also. Unzip the junit zipper. ADD all of the .java files to your new project. Delete the file named orderprocessing2005 that was created by JCreator. You don't need or want it. Remove it from the project itself. Under the MENU Project/Project Settings, select the Required Libraries Tab. Select New and add the junit.jar file as a new required library. You will need to navigat to it. Select OK... Build your project with the Compile project button or menu (F7 works also). Under the Run button, select Configuration and add a new configuration that has OrderEntry as the main class. You hve a new subdirectory named classes. Put the test2.dat file here. Move it, not a shortcut. Put a copy of the junit.jar file here also. Not the original, and not a shortcut -- a copy. Run your project (F5 works). The dialog should show the OrderEntry class. Enter customer C5002 in the field at the top. The rest of the fields at the top should be filled in automatically. Hit the close box -- no others. The first part is properly installed. Double click the junit.bat icon in your directory window. You should get a gui that shows a green bar. You are completely installed.
