applicationContext.xml，dwr.xml，web.xml三文件放在WebRoot/WEB-INF下

DWRimpl.java

Java code

package test;import java.util.ArrayList;import java.util.List;public class DWRimpl{    public String TestUserName(TestBean bean){    //检验用户名        if(bean.getName().trim().equals("admin")){            return  "恭喜,你输入的用户名正确!";        }                return  "你输入的用户名错误,请输入admin!";    }        public List<TestBean>  FindAllNames(){    //获得所有用户记录        //此例子中没用到hibernater,那就模拟一个数据，若用到hibernater就根据自己逻辑操作数据        List<TestBean> tt=new ArrayList<TestBean>();                for(int i=0;i<5;i++){            TestBean tb= new TestBean();            tb.setName("用户名"+(i+1));            tt.add(tb);        }                return tt;    } }

DWRtest.java

Java code

package test;import java.util.List;public class DWRtest{    private DWRimpl bean;        public DWRimpl getBean(){        return bean;    }        public void setBean(DWRimpl bean){        this.bean = bean;    }        public String TestName(TestBean testbean){        return this.bean.TestUserName(testbean);//校验用户名    }        public List<TestBean>  getData(){        return this.bean.FindAllNames();//获得所有用户记录    }}

TestBean.java

Java code

package test;public class TestBean{    private String name;//用户名        public TestBean(){              }        public String getName(){        return name;    }        public void setName(String name){        this.name = name;    }    }

前台提交时总是提示我“DWRUtil”未定义或 “Test”未定义，哪错了？
哪位大虾知道，谢谢了。
