I used to working with JSP as view technology. But with JSF-2.0, the new push is for developers to use Facelets as their templating technology. But whether this is a serious matter? Will I lose anything if i will continue to use the JSP for views in JSF? Than exactly this technology is better? Is there any fundamental differences between the work XHTML and JSP? I would be very grateful if someone could answer it! Thank you

    New view scope and the inclusion of Facelets is major improvements of JSF along with support ajax and annotations. This technology is a very important and powerful property in the JSF 2.0. So I would not recommend ignore it without having a necessity.

    JSP is discouraged from JSF 2.0, because Facelets provide with a much clearer and flexible mechanism for developing user interfaces than legacy JSP. Facelets are far better for several basic reasons:

    • Facelets tags don’t need declaration in a tag library descriptor file(TLD).
    • Attributes in a tag are dynamic and they automatically get mapped to a properties. This is one of the main features not available in JSP is page.
    • Very usable page-templating feature. You define a template that defines a generic layout to all the view pages with the scope for customization.
    • JSP-side of the JSF specification is standing still. None of the new features that involve new tags (composite components, ajax, system events, etc…) are exposed through JSP.
    • In addition, Facelets are faster in execution than JSPs.

    In general, JSP as view technology in JSF 2.0 is considered more trouble and difficult to maintain
