The current logic of being able to register a namespace to class mapping does not work for families of descriptors like javaee that reuse the same namespace across all of the descriptors. The only indication of a difference as the time resolution is done is the optional schemaLocation information: | <web-app xmlns="http://java.sun.com/xml/ns/j2ee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" | version="2.4"> | | <ejb-jar xmlns="http://java.sun.com/xml/ns/j2ee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd" | version="2.1"> | | Either the schemaLocation needs to be looked at, and a schemaLocation,class pair used to register a class, or we allow multiple class bindings for a namespace to create an uber SchemaBinding with multiple root elements. The latter seems like it would work, but I have not looked into it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4093705#...
