使用Spring MVC

Question

 The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.

 Tried the code like 10 times...

  

您好，这是我的Spring MVC Hello Name示例。

Hello World ...

<form action="./hello.ds">

Name:<input type="text" name="name"/>
    <input type="submit" value="say Hello..."/>


</form>

<!-- success.jsp-->

${msg}
