通过网上查找发现错误原因有两个

1.在web.xml中含有<display-name>,这个标签在weblogic中不支持

2.web.xml中

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

weblogic10.3.5不支持web 3.0 改为2.5或更低，我的改为2.5就好了
