修改web.xml，在web-app下面增加如下代码

<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>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

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

<url-pattern>/dwr/*</url-pattern>

</servlet-mapping>

1.配置文件dwr.xml

<dwr> <allow><create creator="spring" javascript="devResponsorService">    <param name="beanName" value="devResponsorService"/></create>

<allow>
<dwr>
2.jsp页面引用
<script type='text/javascript' src='../dwr/interface/devResponsorService.js'></script><script type='text/javascript' src='../dwr/engine.js'></script><script type='text/javascript' src='../dwr/util.js'></script>

3.写java
public int devResponsorQryByNo(String no) {    String hql = "from DevResponsorTable where reponserNo = '" + no + "'";    List alist = this.getShepherd().getAllResult(hql);    if (alist.size()>0) {      return 1;    } else {      return 0;    }}
4.写js
function method(){
devResponsorService.devResponsorQryByNo($("no").value,function devResponsorQryByNo(data){if (data){var sure = confirm("***");if(sure) {form1.submit();}}else{form1.submit();}});
}
