Presentation layer and the Spring Framework
You can use the Spring Web model view controller (MVC) framework and the Spring Framework Portlet MVC framework with WebSphere® Application Server.
Web MVC framework
Web MVC frameworks that are delivered, used, and supported directly by WebSphere Application Server include JavaServer Faces (JSF) and Apache Struts. The Spring Web MVC framework can also be used by applications deployed to WebSphere Application Server. Spring documentation describes how to integrate Spring with these Web MVC frameworks. Use of any of these MVC frameworks is supported by WebSphere Application Server, although IBM® provides product support only for the frameworks that are shipped with WebSphere Application Server.
Portlet MVC framework
The Spring Framework Portlet MVC framework can run in the portlet container in WebSphere Application Server Version 6.1 and later. To run portlets in the portlet container, you must create an additional web application to define the layout and aggregation of the portlets. For details about how to use the portlet aggregator tag library, see the related topics.
