weblogic.descriptor.DescriptorException: Unmarshaller failed

今天写了一个webservices项目部署到weblogic时报出如下异常：
<Error> <J2EE> <BEA-160197> <Unable to load descriptor D:\bea\user_projects\domains\base_domain\autodeploy\TestWebServiceServer/WEB-INF/web.xml of module TestWebServiceServer. The error is weblogic.descriptor.DescriptorException: Unmarshaller failed

多方调试，最后在网上看到说是weblogic的版本兼容问题，将原web.xml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
.......
改为下面的格式后：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_5.dtd">
<web-app>
........
问题解决，web服务可以正常访问。
