Weblogic热部署的问题。。。或者是weblogic工程项目配置的问题
急！！！！！！
weblogic部署成功，感谢老紫竹！！！

调试的时候又出新问题，第一次怎么都没事，每当修改一个java文件Eclipse编译成class文件并自动放到部署目录中的时候，总会报下面的错误。。。。。弄了两天了啊！！

个人猜想是web.xml配置问题，附：(这样配置有问题吗？)
  <listener>
  <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>
   
  <!-- Spring listener -->
  <listener> 
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
  </listener> 

<servlet>
<servlet-name>UP-Dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/resources/ms/spring-ms.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>UP-Dispatcher</servlet-name>
<url-pattern>/service/ms/*</url-pattern>
</servlet-mapping>
 
 
<!-- video dispatcher mapping-->
  <servlet-mapping>
  <servlet-name>UP-Dispatcher</servlet-name>
  <url-pattern>/ms/video/*</url-pattern>
  </servlet-mapping>


------解决方案--------------------
不懂了！org.springframework.web

这个东东没用过！
------解决方案--------------------
感觉这个配置文件怪怪的
<servlet> 
<servlet-name>UP-Dispatcher </servlet-name> 
<servlet-class>org.springframework.web.servlet.DispatcherServlet </servlet-class> 
<init-param>
<param-name>contextConfigLocation </param-name>
<param-value>/WEB-INF/classes/resources/ms/spring-ms.xml </param-value>
</init-param>
<load-on-startup>1 </load-on-startup> 
</servlet> 
红色部分拿出来这样写

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/resources/ms/spring-ms.xml
