DWR如何与webwork结合使用

webwork的result 你想怎么用 就怎么写一个呗

他的PPT上只是简单提到了和ww在action层次的集成,太不详细.并没有这方面的指导

import java.io.IOException;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.opensymphony.webwork.ServletActionContext;
import com.opensymphony.webwork.dispatcher.WebWorkResultSupport;
import com.opensymphony.xwork.ActionInvocation;



public class AjaxJsonResult extends WebWorkResultSupport {
private static final long serialVersionUID = -3778230771704661631L;
Log log = LogFactory.getLog(this.getClass());
protected ActionInvocation invocation;
   
    public void doExecute(String location, ActionInvocation invocation) throws IOException {
Map<String, Object> map = new HashMap<String, Object>();
Enumeration names = ServletActionContext.getRequest().getAttributeNames();
while(names.hasMoreElements()){
      String name = (String) names.nextElement();
if(name.indexOf('.')<0){             
//表示是我们自己set到request中去的对象
Object obj = ServletActionContext.getRequest().getAttribute(name);
map.put(name,obj);
  }
}
StringBuffer jsResult=new DWRJsonMarshaller().marshall(map);
log.info(jsResult.toString());
ServletActionContext.getResponse().setContentType("text/plain charset=\"utf-8\"");
ServletActionContext.getResponse().getWriter().write(jsResult.toString());
    }
   
}

非常很感谢楼上的热情回答，我明白一点了．不过这样，ｄｗｒ服务端好像根本没有用.就是说这样的方式,我看不到dwr在哪里.而且dwr的主要亮点就是javascript访问java方法,这里去掉了,那么仍然有dwr使用的意义吗
