Struts framework versus JavaServer Faces
JSF is in its early access release and as a result somewhat
immature.
Command design pattern. Struts framework has got
only single event handler for the HTTP request.
The heart of JSF framework is the Page Controller Pattern where
there is a front controller servlet where all the faces request go
through with the UI components and then fire off events for each
component and render the components using a render toolkit. So
JSF can have several event handlers on a page. Also JSF
loosely couples your model, where it can hook into your model (i.e
unlike Struts your model does not have to extend JSF classes).
JSF was built with a component model in mind to allow RAD. JSF
can be thought of as a combination of Struts framework for thin
clients and the Java Swing user interface framework for thick
clients.
Has got flexible page navigation using navigation rules
inside the struts-config.xml file and Action classes
using maoping.findForward(…) .
JSF allows for more flexible navigation and a better design
because the navigation rule (specified in faces-config.xml ) is
decoupled from the Action whereas Struts forces you to hook
navigation into your Action classes.
migrated to use JSF component tags instead of the
original Struts HTML tags because Struts tags are
superseded and also not undergoing any active
development. You can also use the Struts-Faces
Integration library to migrate your pages one page at
a time to using JSF component tags.
JSF is more flexible than Struts because it was able to learn from
Struts and also extensible and can integrate with RAD tools etc.
So JSF will be a good choice for new applications.?
