dwr.xml的格式

搞了半天，才搞明白DWR框架的dwr.xml如何编写．
格式如下：
<?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="Chat">
      <param name="class" value="[your.package].Chat"/>
    </create>
    <convert converter="bean" match="[your.package].Message"/>
  </allow>
</dwr>
