running ok under Eclipse IDE, I want to either create a java web start or
some other ways of distributing my program so that I don't have to worry
about whether other machines have appropriate set up for my program. I
don't use anything but pure java. Please let me know where to find
additional information. Thanks in advance.

I do not use Fat-Jar. I just use the Eclipse export.
- Select the project
- right click on project and select Export
- select jar file
- select 'Export generated class files and resources'
- select 'Compress the contents of jar file'
- select 'Add directory entries'
- Select finish. 'I take the default for all the next screens'
- I do get warnings but for me they are ok.
I then move the new jar file to where I want to run it.
I do not use the java -jar option. I use the classpath option and invoke
my main class with its package prefix as..
java -classpath ..\lib\test.jar org.hsqldb.util.DatabaseManagerSwing %1
This works for me. All of the files are found

You can just create a bat file with the Java command to run your
program. You could even create a shortcut and put on their desk top.
Just have them double click the short cut.
An example *example.bat* file would have, in my case, the following..
echo off
java -classpath ..\lib\test.jar org.hsqldb.util.DatabaseManagerSwing %1

You may want to try this also using Eclipse. That is, create an
executable jar file. Do the same as before..
- Select the project
- right click on project and select Export
- select jar file
- select 'Export generated class files and resources'
- select 'Compress the contents of jar file'
- select 'Add directory entries'
- HERE do not select FINISH but NEXT
- I select 'export classes with compiler warnings'
- Select NEXT
- Select 'generate Manifest file'
- This is where you make your jar file executable. That is, create a
Manifest file.
- Select 'Browse' for your main class. This is the entry point for
your program. The main class.
- Select FINISH
You now have a jar file that you can exec with the Java -jar command
Hopefully all of your objects .txt or .png files will load.
This is how it is done using Eclipse.
