--------------------编程问答-------------------- peopleInfo.getPeopleInfo(getMessage);
peopleInfo应该改为Info，要和dwr.xml中配置一样，
<create creator="new" javascript="Info"> --------------------编程问答-------------------- 嗯，是的，这个我发最后发现了，还有一处是 <param name="Info" value="com.peopleInfo" />
name的属性值应该是class,我原本以为可以随便起的，其实不然；最后还要谢谢你啊

补充：Java ,  Web 开发
