notes when deploying webpart to SPS2003 server

It's sometimes confusing when you are trying to deploy a webpart to a box where there's no remote debug installed and no Visual Studio either...-_-! Not much of a choice for you if there's anything wrong with your webparts and sharepoint simply just tells you that it's causing a problem , please remove it...

what you need to do is to set the property of from "CallStack" to "true" and set the "CustomErrors = Off" in your web.config. By doing that, you will be able to see the descent error messages as you would in normal ASP.net application .
