确定jar HTML嵌入的类路径

Question

I'm trying to serve an a JAR executable as a web app. I'm having issues figuring out the class path for the "code" attribute. The JAR was originally packaged on a CD-ROM.

Double clicking on the JAR itself (BDH.jar) executes "C:\\Program Files\\Java\\jre6\\bin\\javaw.exe" -jar "C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\BDH.jar"

Double clicking on the bundled .exe executes "Differential Equations.exe" "C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\jre\\bin\\javaw.exe" -Xms134217728 -Xmx268435456 -classpath "C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\BDH.jar;C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\lax.jar;" com.zerog.lax.LAX "C:/Documents and Settings/xxxx/My Documents/3. Current Projects/BDH/Differential Equations.lax" "C:/Documents and Settings/xxxx/Local Settings/Temp/lax29DC.tmp" "C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\jre\\bin\\javaw.exe" -Xms134217728 -Xmx268435456 -classpath "C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\BDH.jar;C:\\Documents and Settings\\xxxx\\My Documents\\3. Current Projects\\BDH\\lax.jar;" com.zerog.lax.LAX "C:/Documents and Settings/xxxx/My Documents/3. Current Projects/BDH/Differential Equations.lax" "C:/Documents and Settings/xxxx/Local Settings/Temp/lax29DC.tmp"

Both of these launch the app successfully.

Oh, I'm using "applet-fu.js" to try and load this. I found a bunch of likely classes inside BDH.jar and have tried loading them without luck:

applet_fu.run(
  {'width':'550','height':'320'},
  {
    'archive':'BDH.jar',
    'code':'com/artmedialab/main/BDH.class'
  },
  '1.4.2',
  '<p>Please install Java.</p>'
);

Any hope of making this work?

Since this is a double-clickable app, turns out I can't use it as an applet (not without changes, anyway). Apparently the way to distribute desktop apps over the web is by using JavaWebStart (sometimes called JNLP). See http://download.oracle.com/javase/tutorial/deployment/webstart/index.html for more details.
