Error in JavaHelp

Question

Hello:
I have JWS app I've been working on for a long time. I just added JavaHelp to it. I got it all working nicely on my local machine. When I went to deploy in JWS, I ran into a permission problem. JavaHelp is included as an extension, and I've set <security> to <all-permissions/> in both JNLPs, but I still get the following exception:
Parsing failed for null
Exception caught while parsing nulljava.security.AccessControlException: access denied (java.util.PropertyPermission user.home read)
java.lang.NullPointerException
  at javax.help.plaf.basic.BasicFavoritesNavigatorUI.reloadData(BasicFavoritesNavigatorUI.java:297)
  at javax.help.plaf.basic.BasicFavoritesNavigatorUI.installUI(BasicFavoritesNavigatorUI.java:235)

  at javax.help.JHelpNavigator.<init>(JHelpNavigator.java:105)
  at javax.help.JHelpFavoritesNavigator.<init>(JHelpFavoritesNavigator.java:62)
     ... more omitted
Here are my JNLP files:

Any and all help welcomed.

Thanks for the quick response. I downloaded your app (very good idea BTW!) and ran it against my JNLP file. It reported a number of issues to me, but I don't understand them. I subsequently located the JNLP spec 6.0.10 here and went through it carefully. (I ended up discovering some nice features I added to my file.) I ended up with the following file, but the errors seem to be the same. The output is below the JNLP.
Is it possible that your app is analyzing against an outdated version of the JNLP spec? It's all that I can figure. Perhaps you could explain just one or two of the node errors to get me started. Thanks again! Dan

Codebase + href 'http://www.digibunker.com/digibunker.jnlp' is not equal to actual location of 'file:/Y:/Moonlighting/JudeDavid/site/athena/public/digibunker.jnlp'.
Downloads can be optimized by specifying a resource size for 'digibunker.jar'.
The resource download at digibunker.jar can be optimized by removing the (default) value of download='eager'.
The resource download at digibunker.jar can be optimized by removing the (default) value of main='false'.
It might be possible to optimize the start-up of the app. by specifying download='lazy' for the digibunker.jar resource.
Lazy downloads might not work as expected for digibunker.jar unless the download 'part' is specified.
Resource type com of resource http://digibunker.com is not one of the allowable types of jar.
