dwr2.0與dwr1.1的區別

一、web.xml配置
   <servlet>
      <servlet-name>dwr-invoker</servlet-name>
      <display-name>DWR Servlet</display-name>
      <servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
      <init-param>
         <param-name>debug</param-name>
         <param-value>true</param-value>
      </init-param>
  </servlet>

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

<servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>與dwr1.1<servlet-class>uk.ltd.getahead.dwr.DWRServlet</servlet-class>有變
<servlet>放於servlet一起，<servlet-mapping>放於<servlet-mapping>一起
二、包名需要改變：DwrUtils.getValue  需要將DWRUtil改爲dwr.util.
<script language="javascript">
function update2()
{
   var kcid=dwr.util.getValue("fbpt");
   alert(kcid);
   TeacherSelect.getTeacherInfor(kcid,createList2);
}
function createList2(data1)
{
    dwr.util.removeAllOptions("xmlb");
    dwr.util.addOptions("xmlb", data1);
}
</script>

注意參數要放在前面，回調函數放於後面TeacherSelect.getTeacherInfor(kcid,createList2);
與dwr1.1相反

三、dwr.jar放於WEB-INF的lib下面  ,dwr.xml放於WEB-INF下面
