 ======

后来又报了Caused By: java.lang.LinkageError: loader constraint violation: loader (instance of weblogic/utils/classloaders/ChangeAwareClassLoader) previously initiated loading for a different type with name "javax/xml/namespace/QName"

经查，为javax/xml/namespace/QName冲突所致，weblogic下删除stax-api-1.0.1.jar的jar包即可。
