今天试着写了个httpInvoker做远程调用，以便项目以后要扩展成分布式开发的。
但是一直报404找不到错误，我试着查了一下，确定自己配置文件都没有写错。把代码贴出来 希望各位高手解答疑惑 谢谢server端web.xml

就是会报404错误，但我实在看不出来哪里配置有错。
我直接在url里面输入http://localhost:7001/AssiTwo/remoting/ProductService
也找不到 
希望各位高手支支招啊！！
分全给了！急啊！

remoting-servlet.xml加上：
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/ProductService">/ProductService</prop>
 
</props>
</property>
</bean>
