the webapp contains xerces-1.4.4 in WEB-INF/lib, this jar includes org/apache/xerces/jaxp/DocumentBuilderFactoryImpl.class.
but the part that's not a tomcat-"internals" issue does not have to be discussed here, probably the tomcat-user-list is a better place for this...
Without a security manager, any application can set system properties, which are global. So here the JAXP settings will be changed for the whole system, which will produce random results (since only your webapp has visibility on the Xerces class) :(
There are clearly better ways to influence JAXP than this...
If there are no other META-INF services entries for document builders in the class loader prior to the web app's (which I believe is the case in 5.5), then just having your Xerces (which should have such a META-INF entry) in your web app should suffice.
But honestly, Xerces 1.4.4!?! That's positively ancient.
