This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Please read ItDoesntWorkIsUseless and TellTheDetails: you wouldn't expect an auto mechanic to diagnose and solve a problem with your car without being able to look at the car. We're not at your machine and have no other information other than what you choose to share--without knowing what's happening, what you expected, what (if any) errors you received, and so on, it's impossible to help.
Post stack trace details, without them, anything we come up with is a guess. Line number(s), the actual exception message, and so on.
