 Thanks for the reply Jon.

    It's part of the core java security model. If a package is 
    sealed within a jar then packages of the same name cannot 
    be defined in another jar, or elsewhere on the classpath.
    Within the manifest file of the jar file which is being 
    loaded by your putpr servlet you'll probably have a couple 
    of lines like:
    Name: nu/xom
    Sealed: true
    The XOM jar that I have (xom-1.0d8.jar) doesn't seal its 
    packages. So, you need to find the jar which is sealing the 
    nu.xom package and stop it doing so. (Or work out your xom 

I'm guessing its xercesImpl jar? Having removed it the error 'went'.
I also got a clue, just import nu.xom.*; rather than individual ones?
 Unsure which  one cleared the error,
but its OK now.

  What the heck do I do if I want xom to validate?
