Simple example

for more information, please visit our forum thread on the extjs website.

Server side

Create a new servlet on your project :

import ch.swissdotnet.extdirect4j.*; public class MyExtDirectRouter extends ExtDirectRouter { @ExtRemoteAction(name = "Action", lazyInit = true) static public class TestAction { @ExtRemoteMethod public Result multy(long a) { return new Result(a * 2, "just a result"); } } @Override protected void configureActions() { this.addAction(new AnnotatedAction(TestAction.class)); } }

Javascript side

Add these line to your index.html : <script src="MyExtDirectRouter" type="text/javascript">

This will call the Ext.Direct router and set the var Ext.app.REMOTING_API with the followin json object :

Ext.app.REMOTING_API = {"url":"http://localhost:8080/ExtDirectDemo/MyExtDirectRouter","type":"remoting","actions":{"Action":[{"name":"multy","len":1}]}};

Now the provider can be added to Ext.Direct, and the remote methods can be used :

``` Ext.Direct.addProvider(Ext.app.REMOTING_API);

Action.multy(num.getValue(), function(result, e){ var t = e.getTransaction(); if(e.status){ alert("answer is " +result.result + ', message : '+result.msg); } });
```
