Can anyone tell me what happens when we set a null key object e.g. request.setAttribute(null,new Integer(4)); in the request.setAttribute method in a jsp.Is there any exception thrown. I tried it and on the local machine no exception was thrown but when i tried to access the jsp remotely then an IllagalArgumentException was thrown. Please can anybody explain me the exact functionality of the request.setAttribute method.

Thanks in Advance.

The spec and APIs don't specify what should happen if a key is null.

There really shouldn't ever be a scenario where there could be possible in your application.
