Interface APIAwareDispatcher

public interface APIAwareDispatcher

Servlet API 2.0 does not have the RequestDispatcher interface. Apache-JServ is based on Servlet API 2.0. For those users that are using JServ, this interface allows the use of the RequestDispatcher forward() and include() methods by hiding the API differences between the Servlet API 2.0 and 2.1 This class is used in conjunction with the com.jcorporate.expresso.core.jsdkapi.GenericDispatcher class.
