DWR

****************************Dwr2.0****ajax框架**************************

 

Dwr→divect web remote ：直接远程方法调用

1．  导入jar包(dwr.jar)

2．  配置web.xml

<servlet>

        <servlet-name>dwr-invoker</servlet-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>

3．  建立dwr.xml文件,web.xml同级目录（web_inf）目录下面建立。

dwr.xml中的内容：

<!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="随便取个名字">

          <param name="class" value="包名.类名" />

      </create>

    </allow>

</dwr>

4．在head之间导入js

<script type='text/javascript' src='dwr/interface/在dwr.xml随便取的那个名字.js'></script>

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

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