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.
What do you mean by "contains all S2 files"? What libraries are you deploying?
From the stack trace it looks like you've deployed the REST plugin, which is almost certainly not what you want if you're not using it--the "create" method is the default method called by REST plugin form POST submissions.
If you're not actually using a plugin you must *not* deploy it; it may have additional library dependencies or alter the way your application works.
