openMapApplet and .jar data

Hi guys,
        I am trying to get layer data including DTED and Political
Boundaries working with the data in a .jar file, and have tried changing the
com.bbn.openmap.io.BinaryFile.java file to use
Thread.currentThread().getContextClassLoader().getResource(name); but this
results in th following error (using JRE Plugin 1.3.1_02, latest apache,
NT4, Netscape 6.2):

*** ERROR ***

where my applet is at http://host.name.com/openmap/
with 2 jar files, openmap.jar that contains the altered BinaryFile.class
and data.jar that contains a layer I am creating and the DTED and Political
Boundaries data

Any ideas why java is acting as if the jar is a local file that I don't hava
permission to access?

thanks,
        Barney
