Well it got past the problem of the downloading the jnlp file itself.
Now it is choking on finding the jars.

I didn't know that you had the directory listable for 
http://www.crosswire.org/jsword/jnlp
or I would have seen it earlier.

So changing codebase and not href was the thing to do.
<jnlp spec="1.0+" codebase="http://@HOSTNAME@/@WEBAPP@/jnlp/" 
href="jsword.jnlp">

However, I think that there are other problems. One of which you mention on 
the WebStart web page.

1) WebStart is known to have problems with using xerces and xalan under 1.4. 
Specifically, the mechanism (Endorsed Standards Override) to replace 
built-in (e.g. crimson) with other (e.g. xerces) functionality is not 
supported.

[ There may be a similar need for Tomcat to use the endorsed dirs.
See: http://java.sun.com/webservices/docs/1.2/jaxp/Updating.html ]

2) I had problems loading jlfgr icons from a jar into an application, unless 
I used absolute pathing. Jsword uses relative pathing and has the resources 
in the file system, not in a jar when run as an installed application. 
WebStart requires stuff to be in jars.

3) Not all of the jars needed are present in the distribution directory.

4) Not all of the jars needed are mentioned in the jnlp file.

If you like I can work on getting 2-4 working, and I can see if I can find a 
work-around for 1.

But, if JSword 1.0 provides a different mechanism for installation, then 
this work would not be needed.
