However I was thinking if there is any way to use the existing web application built with JSF framework to directly access in ios as we can do it in the android environment.
I went through the Phonegap again & found the following info:
Q. Can I just create an iPhone PhoneGap-based app that just loads my website?
A. You can, but as for Apple approving it, that's another matter, and they most likely won't. As a rule of thumb, if there is no Internet connection, you must at least load the UI (your views) without the corresponding data, and put an error notice to that effect. Therefore your app must have these views included in it. For a guideline, set your iPhone to Airplane Mode in the Settings, then load either the Maps, Weather, Youtube, ITunes or Facebook apps, and see what they do (have a "shell"). Apple is probably concerned about them approving your app based on your app description and functionality as promised by you, and then you turning around and changing it completely after approval to something undesirable.
Thanks for providing the information.
