The files in this directory are designed
to remind you of one way to create an
executable jar file, and also to show
you how to include a "help file" in the
jar file so that the program contained
in that jar file can read and display it.

First make sure you have created a J:\jxtra
directory (here at SMU) or a C:\jxtra
directory at home or on your laptop,
and that it contains all the .class
files in the jxtra subdirectory under the
Additional Files | jxtra
link on the course website. You will only
use the TextItems.class file here, but you
might as well download them all, since you
will be using others in your submissions.

Then make sure you have all the following
files (put them together in any location
you like):
ExecutableJarFileWithInternalHelpFile.java
ExecutableJarFileWithInternalHelpFile.mf
helpfile.txt
jc.bat
jr.bat
jar_c.bat (needs jar.txt)
jar_r.bat
jar.txt

Next (but only if you're running at home
or on your laptop):
In jar.txt, jc.bat and jr.bat change
J: to C: so that you go to the right
jxtra location.

Now run the batch files in the following order:
jc.bat (to compile the .java file)
jr.bat (to do a test run of the executable class file)
jar_c.bat (to create the jar file)
jar_r.bat (to do a test run of the jar file)

Notes:
1. It would be helful (and instructive) to study the
   batch files and repeat the above process by typing
   in the various full commands instead of running the
   batch files.
2. Be sure to study how the helpfile.txt is accessed in
   the .java file, since this is how it must be done if
   it is to be accessible by the program from within the
   jar file. It would also be instructive to change the
   name of the file helpfile.txt to see what error you get.
