GWT framework for iphone

i know Java,not Objective-c but like to program IPHONE and IPAD. now i need to use some sort of framework directly for device communicat开发者_Python百科ion and function communication(http connection API,barcode reader API,remote file access API,twitter API) is there any framework that is written in Java using GWT.

i saw phoneGAP.but like GWT.

i like GWT but like some sort of framework(Device API + Function API) on top of GWT.

is there any suggestion?

GWT is a Java-based framework. GWT or wrappers around GWT will not work on the iPhone or iPad, because native app development for those platforms requires writing code in C, Objective C or C++.

Why not use PhoneGap? I've used it for a GWT based application and it works great. You just need to wrap the PhoneGap API that you need in a JSNI call, but otherwise it works great.

You cannot create a native iphone/ipad app using GWT (except perhaps through PhoneGap), but you can create a web page using GWT which will run on a server. The iphone/ipad can then access the app using it's browser. With HTML 5, you can do some advanced things such as access the GPS store data in a local database etc.
