Question

I would like to work with Sencha Touch, but there is a small problem: I don’t know JavaScript or how I would begin using Sencha Touch in JavaScript.

I already have a commercial license for Sencha Ext GWT and develop applications with it in Java.

What I need is Sencha Touch wrapped as a Java component or some guides on how to make my own Java wrapper for Sencha Touch.

I have looked at GWT4Touch, but it does not meet my requirements.

Can someone help me?

I also had the same issue a few weeks back. I didn’t knew Javascript but I wanted to use Sencha Touch for prototyping(work related). I came across this book “Sencha Touch Mobile JavaScript Framework“:

Actually if you read this book developing apps with Sencha touch is not that hard. I was able to develop a prototype in a week where I built UI pages using Panels, toolbars , MVC, remote proxies. I even integrated all this with Java Spring and Freemarker templates.

Here is the Store code to call the remote ajax proxy:

proxy: {
        id: 'proxyID',
        type: 'ajax',
        url: '../api/sampleRestJsonAPI',
        reader: {
            type: 'json',
            root: 'data'
        }

You have to setup Java Spring (With MVC) so that when your code makes a call to the remote proxy it gives you something like:

{"data": {"field1":"value1", "field2":"value2"}}

Basically it should be a valid Json with the root you have specified in your store. The url config option might change based on how you structure your folders in your web app.

So with this I do all the heavy duty data processing in the Java Layer and keep the js layer very light.
