I posted this about a week ago with no luck. Anybody care to comment? I'm trying to use Xerces in my web application. To do this I put the jar file into WEB-INF/lib. However whenever I try and parse any XML I get a 'sealing' exception. I've just read the recent thread on this and it implies that I can only have one XML parser within Tomcat, or at least that if the class names clash (which they will) things may not work as expected. Can I use Xerces either alongside Crimson? If so, where do I put it. It doesn't work in WEB-INF/lib and only works in tomcat/lib as a replacement for crimson. Reading the sealing discussion I get the impression that using Xerces should be OK as long as the class loader doesn't try and use two classes with the same name from different jars, (or am I way off the mark here?). So shouldn't xerces become the 'default' XML parser for my application? What if I want to use a different parser (such as Oracle's) will it work (I haven't tried this BTW)?
