How to create a mobile interface for Grails apps?

I'd like to have开发者_Python百科 a mobile interface for my Grails app, and am wondering how to go about it, namely how to create the UI. Google search quickly revealed iUI and the iUI Grails plugin. Both don't seem to be maintained any longer, last releases being in 2009. Despite their version numbers, are they in a usable state? Are there any alternatives? I remember seeing another plugin for this, but now I cannot find it.

Right now, all we have are iphone clients. In the long run, does a web-app benefit from a vendor-neutral interface, or is it more prudent to create an interface per platform?

I can suggest that you look at Mobl-lang, JQuery Mobile or PhoneGap as your frontend and let your Grails app deliver data to the frontend as JSON

There is grails plugin for iphone like layout http://www.grails.org/plugin/iwebkit.

Here is the reference to stack-overflow ticket which discusses the same issue.

iWebkit vs. JQTouch vs. iUI
