跪求帮忙解决weblogic 10.3.3 jar包冲突

1、好像是项目的xerces-2.6.2.jar 与 weblogic 或 jdk1.6.0_22 的某个jar包冲突2、我把项目的xerces-2.6.2.jar 删除掉 不行（javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/xerce
s/parsers/AbstractSAXParser）3、我把DocumentBuilderFactoryImpl.class从xerces-2.6.2.jar删除掉 还是和 没删除xerces-2.6.2.jar一样的错误。下面是没删除项目的xerces-2.6.2.jar 的异常：
