解决办法：

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90"
    xmlns:j2ee="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.bea.com/ns/weblogic/90

    </container-descriptor>
    
    <context-root>/cdjp</context-root>
    
</weblogic-web-app> 

找到weblogic.xml文件处标红的地方，若为true，则改为false
 <prefer-web-inf-classes>ftrue</prefer-web-inf-classes>什么意思？就是指优先加载web-info下的lib中的jar包
