I’m getting my hands on JSF 2.0 and have certain doubt about new annotation

  • 0

I’m getting my hands on JSF 2.0 and have certain doubt about new annotation based auto-wiring (declaration of managed beans without any code in faces-config.xml).

As far as I am annotations are great and easy, but problem may come to a certain need of substituting one bean with another in a big system which, if annotations were used, will result in a need to delete certain classes (or similar dirty hack), while it could be easily fixed in faces-cofig.xml.

Please, share your experience on the matter. What should be considered more convenient and why?

    As was said in Core JavaServer Faces (Third Edition):

    Before JSF 2.0, all beans had to be configured with XML. Nowadays, you have
    the choice between annotations and XML configuration. The XML configuration is rather
    verbose, but it can be useful if you want to configure beans at deployment time.

    Annotations allow rapid development and reduce redundant xml coding. Generally, it greatly depends on the project itself.
