dwr 설정

1. dwr 다운로드
http://directwebremoting.org/dwr/download.html

2. WAS WEB-INF/lib/  에 라이브러리를 추가하고

3. web.xml 에 dwr servlet 을 추가한다.

<servlet>
      <servlet-name>dwr-invoker</servlet-name>
      <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
      <init-param>
           <param-name>debug</param-name>
           <param-value>false</param-value>
      </init-param>
</servlet>

<servlet-mapping>
      <servlet-name>dwr-invoker</servlet-name>
      <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>


4. dwr.xml 을 WEB-INF/ 에 생성한다.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN" "http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
  <allow>
        <create creator="new" javascript="DwrSvc" >
               <param name="class" value="package.DwrSvc"/>
                   <include method="update"/>
        </create>
  </allow>
</dwr>


5. http://localhost:8080/dwr/  확인한다.

6. jsp에서 자바스크립트 넣는다.
<script type='text/javascript' src='/vs/dwr/interface/DwrSvc.js'></script>
<script type='text/javascript' src='/vs/dwr/engine.js'></script>

<script type='text/javascript' src='/vs/dwr/util.js'></script>


7. 실제 자바스크립트에서 호출한다.

<script type='text/javascript'>
 function dwrGo(param){

 DwrSvc.update(param, rsFunction);
 }

 function rsFunction(rsdata){
     alert(rsdata);
 }
