The following assumes you have imported chess.zip from the course myWPI site into Eclipse as a project. If not, then you will need to familiarize yourself with the general concept of resource loading and the use of the jar utility.

Don't forget to update your javadoc (Project>Generate Javadoc) and the toplevel README.txt file in the 'turnin' directory before creating your jar file to turn in!

Note that the 'turnin' directory already contains an example chess.jar file, which was created from the small Chess example program provided to illustrated loading a model.

• Using the command line (not Eclipse)...
• Make 'turnin' the current working directory (cd).
• Try executing the provided chess.jar file by invoking the "run_chess.bat" or "run_chess" command file.
• You should see the base of the black King. Type 's' to move it farther away.

Here are the steps in Eclipse to make a new chess.jar file containing your homework:

• Right click on chess.jardesc and select Open Jar Packager.

• Under "Select the resources to export", check all and only the folders that are needed for the current homework.
  • always leave the default package and edu.wpi.imgd4000 checked
  • make sure the 'doc' folder (containing javadoc) is checked
  • check the README.txt file if you have added one
  • check any packages you have added for your homework
  • do not check the models folder (to keep jar file conveniently small)

• Make sure that both "Export generated class files and resources" and "Export Java source files and resources" are checked (the other two options in this list should not be checked).

• Make sure "Export class files with compile warnings" is checked on second page of menus.

• Click Finish.

• If you later edit your code, but have not defined any new packages, and want to create a new jar file, you can simply select Create Jar instead of Open Jar Packager.

• (FYI, the jar file thus created will not contain either the distributed chess models or the jME libraries, since the TA will run your code in the same chess project environment. However, if you look at the manifest file for chess.jar, which is generated from chess.mf, you will see the correct classpath references to these shared resources.)

Make sure you verify that your jar file is correct using the run_chess command in the command shell, before uploading it to Web Turn-In!

Finally, upload the chess.jar you have created to Web Turn-In.

Warning! As with any online submission system, it is always a good idea to verify that you see you uploaded file online before logging out of Web Turn-in.
