[OT] Re: Adapter Vs Business Delegate

Whats this got to do with Struts?

Adapter is a very general pattern that converts the interface of one 
class inot a different interface.
Business Delegate is a pattern specific to enterprise-apps that aims to 
decouple the business services from the presentation tier.  A Business 
Delegate hides implementation details like JNDI lookups etc from the 
presentaton tier, it is therefore much more than an adapter (which is 
usually just a dumb object which delegates all incoming requests). 
However since a Business Delegate often transforms the interface of the 
business service into another interface which is more friendly to the 
presntation-tier it may be thought of as a type of adapter.
