변경의 dwr.xml 파일의 항목은 자바 스크립트 클래스 이름을 호출하는 것보다 자바 Class 이름을 불렀다

<create creator="new" javascript="DwrSampleTest"> 
     <param name="class" value="com.dwrsample.servlet.DwrSampleTest"/> 
    </create> 

Javascript ="DwrSampleTest" must match with the service name that you call in jsp page .

을 다음과 같이.

는 얻을 디버그는

<init-param> 
      <param-name>debug</param-name> 
      <param-value>true</param-value> 
     </init-param>

변화를 참 PARAM 값을 수 있었다.
