My application works perfectly local but not in the remote server

When I upload the files on the remote server I get the following message:

Obj开发者_StackOverflow社区ect reference not set to an instance of an object

And a few errors supposed to be happening in the ClassDesigner file and other few classes.

The error message you give is to general to help. It basically means you are trying to access a object that is null. Please at least give a stack trace.

You have a bug in your code.

You need to read the details of the exceptions and find and fix the bug.
