The Struts User's Guide suggests that business logic be encapsulated in beans. Business logic modules are generally stateless, so one would generally implement them as static utility classes (with only static methods) or singletons (with private constructors and static factory methods), neither of which can be "beans" (which, by definition, have public constructors). To effectively manage stateless classes as beans (without re-instantiating them for each use), one would have to implement a lookup/mapping mechanism (an "EJB-lite"). Are the Struts developers suggesting that we develop such mechansisms? Might such a mechanism be slated for a future version of Struts?
