因为创建项目的时候用的是JAVAEE6，所以生成web.xml文件的时候是这样的：

[java]  view plain  copy

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

　weblogic10.3.6并不支持web-app_3_0.xsd的定义。所以报错了。

　　改为如下就ok了：

<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    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/web-app_2_5.xsd">
