栈跟踪:在System.Web.HttpServerUtility.ExecuteInternal() ||在MVC 2

在部署我的MVC 2.0项目到服务器时，我得到以下错误。当地一切都很好。我想找出这个错误。

我们使用HttpWebRequest来实现这个功能。

对于整个站点词汇表搜索，我们创建了这个控制库。本地搜索正在进行，但在服务器中搜索时显示空页面。我的文件异常显示以下错误提示。有谁能帮我解决这个异常吗?

1.If your controller doesn't provide a model instance i.e: the model cant be instantiated.
2.You might be missing some stored procedure which returns data to your controller during deployment.
3.Check your connection strings in web.config. It should be in acceptable format.
4.Some how the application cannot initialize database connection.
