Using DOM Level 3 Load and Save...

[Michael Burbidge]

I'm trying to determine the correct way to get the serializer using  
the DOM Level 3 Load and Save functionality support by Xerces. I'm  
using version 2.8.1. According to the book "Java and XML" this is the  
appropriate way to get an LSSerializer:

			DOMImplementationRegistry domRegistry =  
DOMImplementationRegistry.newInstance();
			DOMImplementationLS domImpl = (DOMImplementationLS)  
domRegistry.getDOMImplementation("LS");

But when I do this the second call returns null. I'm trying to use  
this from a servlet that is deployed to Tomcat. The xerces jar is on  
my class path. Is there something I have to do to get the xerces  
versions of the load and save classes registered in the registry? Is  
there a more appropriate way to get the right LSSerializer from xerces?

Thanks,
Michael-
