이유는 web.xml에 BbsController가 잡혀 있기 때문으로 보임.

따라서 BbnController 부분을 지우고 나서, 

  <servlet>

    <description></description>

    <display-name>BbsController</display-name>

    <servlet-name>BbsController</servlet-name>

    <servlet-class>org.hotsix.web.BbsController</servlet-class>

  </servlet>

  <servlet-mapping>

    <servlet-name>BbsController</servlet-name>

    <url-pattern>/bbs</url-pattern>

  </servlet-mapping>

ajax 부분의 url 부분을 고쳐주니 됨.

url: "reply"

-->>

url: "/reply/getReply",
