We use Chain of Responsibility (CoR) implemented by commons-chain and its Agility to construct a Request/Response framework to connect a request to its designated service, whether the designated service is in a web-application service container, a portlet container, auth for authentication/authorization, or a Jcr container. At the business layer, the designated service may use other services in other containers. e.g. the personalization of auth container uses UserDaoImpl of DAO container. We use Spring IoC to assemble chain Catalogs and their commands. Hence the request/response framework is based on CoR/IoC integrated with your presentation engine at the front. We use Jsf+Tiles as our presentation engine. The good thing is that available infrastructure takes care of detailed connections while isolating the dependencies of itemized services within 1 container and among containers. Developers just need to plug in the required specified functionality based on design contract. We integrate the Request/Response with workflow using Shale Dialog and Spring WebFlow to produce Request/Response/Workflow Business Application Framework. More detailed discussion is in the following link, which will be updated by 2nd week of June after the release of RedHat Fedora 4. http://www.dbgroups.com/docs/architecture.html#BusinessApplicationsFramework Hope this may help.
