wex5中自己写的Bass服务，java代码

silverlong

编译模型也不可以，附件是自己写的。
Baas.sendRequest({
                        "url" : "/dzbz/loginentaty", // servlet请求地址
                        "action" : "loginaction", // action       
                        "async" : false,
                        "params" : {
                                login_name : loginname,
                                userPwd : md5UserPwd
                        },
                        "success" : function(data) {
                         }
});

这样子调用，报错信息如下:
