Caused by: java.lang.LinkageError: loader constraint violation: when resolving field "NODESET" the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) of the referring
class, javax/xml/xpath/XPathConstants, and the class loader (instanceof <bootloader>) for the field's resolved type, javax/xml/namespace/QName, have different Class objects for that type

아래 사이트를 참고로 jboss-web.xml를 java2ClassLoadingCompliance=”true” 로 변경하니 해결됨. http://stackoverflow.com/questions/4985269/jboss-class-loader-order-another-try-to-understand-it
