Avoiding Authentication Challenge when using JSVGCanvas.loadSVGDo cument(URL)

["SANSONE, AARON M [Non-Pharmacia/1000]" <aa...@monsanto.com>]

We are using the Batik API in an Applet to render SVG in a Frame.  Our
applet is deployed via a Solaris system running Apache 1.3.23.  We have gone
to great lengths to allow only a single authentication sign on for our users
(i.e. our Java Plug-in JVM does not ask for authentication from the user).
We accomplished this by setting the default authenticator when our applet
starts, and sending the "AUTHORIZATION" request header when we make URL
Connections back to the web server.

Unfortunately when we attempt to render an SVG Document that has been
retrieved from the web server, the application is requesting DomExtension
and several other classes from the web server.  It is also trying to request
a "null" object.

My applet tags contain the batik-libs.jar file which contain all of these
files (with the "null" exception of course).

<param name="archive"
value="fpclient.jar,batik-libs.jar,crimson-parser.jar,xml-apis.jar,xercesImp
l-2.0.0.jar">

So why am I getting an authentication challenge?

Any help would be appreciated.

Here is the Java Console information.  The first challenge is presented when
trying to get DomExtension.  There is also the null request.
