我试图让从我的PhoneGap应用程序一个Ajax请求的servlet在我的笔记本电脑上运行，  它击中服务器，但AJAX请求总是会出错的一部分。 如果我会做普通的浏览器工作正常了同样的要求。

i am trying to make an ajax request from my phonegap app to servlet running on my laptop, its hitting server but the ajax request is always going to error part. If i will do the same request in normal browser working fine.

function cred() { 
    var username = "hisari";
    var password = "kumar";
    var ul = "ip" ;     

    $.ajax({ 
        type: "GET",
        url: ul,
        dataType: "json",
        success: function(msg, textstatus) {
            alert("success"); 
            if (msg.id != null)
            {
            } else if (msg.error_id) 
            {       
                 //Error    
                alert('Error logging in:' + msg.error_message);
            }           
        },      
        error: function(error) {            
            alert("Error connecting to the servers" + error.message);       
        }   
    }); 
}  

请给我一个解决方案，如果可能的话建议我可以用Servelet的是什么，而不是进行登录验证

please give me a solution ,If possible suggest what can i use instead of servelet for login validation

你有没有加入你的主机config.xml中的白名单？

Have you added your host to whitelist in config.xml?
