}}
所有的情况均无法跳转
如果是从非extjs页面登录的话，则正常

我是用这种方法实现的：
var loginSuccessWindow = new Ext.Window({
width : 300,
height : 60,
closeable : false,
frame : true,
closeAction : 'hide',
items : [
{
frame : true,
html : '登录成功<br/><img src="<%=path %>/images/wait.gif" />正在加载个人设置，请稍后……'
}
]
});

     var btn_login = new Ext.Toolbar.Button({
     id : 'btn_login',
     text : '登录',
     handler : function(){
     if(loginPanel.getForm().isValid()){
     loginPanel.getForm().doAction('submit',{
     waitMsg : '正在登陆，请稍后……',
     url : contextPath+'/userLogin.ext?pmethod=userLogin',
     method : 'post',
     success : function(response, action) {
var message = action.result.message;
//Ext.Msg.alert('提示',message);
loginSuccessWindow.show()
loginWindow.hide();
//window.location.href='${forwardUrl }';
setTimeout(function(){
loginSuccessWindow.hide();
document.location.reload();
},2000);
//alert(${forwardUrl});
},
failure:function(response,action){
var message = action.result.message;
Ext.Msg.alert('提示',message);

}
     });
     }
     }
     });
先将数据提交到你的servlet进行登录验证。然后将验证信息传到前台。再在前台通过js来控制页面跳转！希望对你有用！
掐个断点, 看看你的extjs登录的时候, 能不能进到你的servlet中.
如果进不去, 那么应该是你的form的url有问题
应该是配置文件的问题。建议让其它的人check一下你的XML文件。（因为自己写的自己看不出来）
我是这样做的，正常跳转buttons: [{
                text: '登录',
                handler: loginMethod
         }]function loginMethod(){
      if(menu.getForm().isValid()){
Ext.Ajax.request({
                      url: 'login.do',
                      params: "uname="+Ext.get('username').dom.value+"&pwd="+Ext.get ('pwd').dom.value,
                      success:function(response,options){
                             var result = response.responseText;
                             if(result=="yes"){
                                  loginForm.submit();
                             }else{
                                Ext.Msg.alert('消息','用户名或密码错误');
                             }
                      },
                      failure:function(response,options){
                             Ext.Msg.alert('错误','服务器端失败,请稍后重试');
                      }
                   })
                }else{
  Ext.Msg.alert('错误','请检查输入项');
  }
    }<body>
<form actionadmin/manager.jsp" method="post" name="loginForm">
</form>
</body>
    晕哦，不能编辑了，有些地方没对！刚改的时候改错了~~这样应该就没问题了，后台不需要写跳转
<form action="admin/manager.jsp" method="post" name="loginForm">
</form>
