Two questions about Axis's jaxrpc.jar

[John G. Norman]

Hi.

On the JBoss lists, there are various posts regarding class cast exceptions 
when using Axis (1.1). I think I've seen a few such posts on Tomcat lists 
as well.

In its default setup, JBoss loads JAXP with a different classloader from 
the one used by a web app with no special directives regarding 
classloading. There are ways to change the JBoss classloading strategy for 
a particular ear or war, but many of these solutions are not  very helpful 
if one can't change the server configuration as well.

I have noticed that there are some bits of JAXP in the Axis jaxrpc.jar. 
Specifically:

        javax/xml/transform/dom/DOMSource.class
        javax/xml/transform/sax/SAXSource.class
        javax/xml/transform/Source.class
        javax/xml/transform/stream/StreamSource.class
Two questions:

(1) Why are these in here? Wouldn't a user be expected to load his own JAXP 
classes and expect Axis to depend on that?

(2) I made a new version of Axis's jaxrpc.jar without these items, so that 
Axis just uses the JAXP items that are available as part of normal JBoss 
startup. It seems to eliminate the typical class cast exceptions. Is there 
anything wrong with doing this?
