Linux+WebLogic11g：java.lang.LinkageError: loader constraint violation in interface itable initializa

在项目的WEB-INF目录下，有如下weblogic.xml文件

 xml version="1.0" encoding="UTF-8"?>
 <weblogic-web-app
     xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                         http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd">
      <container-descriptor>
         <prefer-web-inf-classes>trueprefer-web-inf-classes>
     container-descriptor>
 weblogic-web-app>

WebLogic下代码发版成功后，运行某个功能，出现以下错误：

 <2016-3-10 上午11时49分51秒 CST>    <[ServletContext@16524584[app:CEACCSVR module:CEACCSVR path:/CEACCSVR spec-version:null]] Root cause of ServletException.

包冲突，删除以下几个包，就可以了。
saaj-api-1.3.jar 使用axis所需的jar 
saaj-impl-1.3.2.jar 使用axis所需的jar 
saaj.jar 创建到端点的点到点连接的方法、创建并处理SOAP消息和附件的方法，以及接收和处理SOAP错误的方法.
