This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
UseBean requires an object that meets all of the Javabean criteria. One of those requirements is a zero-argument constructor. Since singleton objects have private constructors, you'll need to make sure that something else instanciates and binds the singleton to the desired scope before the JSP that uses it is ever called. A ContextListener comes to mind.
