How to call struts application through JSON

Hi,

How can I make a call to struts 2.0 based webapplication from a mobile application as client ? I know this can be done with JSON, but I am a newbie to both struts and JSON. Can anyone help me.

Hi,

I have a struts2 based web application and I am using json-default to return json result type as response from my action class. I am able to call this action from browser but not from another application, which is a mobile based application that is developed in javascript. Here is my javascript code to call the action in struts web application:

var request = Ti.Network.createHTTPClient(); 
btn.addEventListener('click',function(e)  
		{  
		 if (name.value != ''){  
		request.open("POST","http://localhost:8080/Message_Resource_Struts2_Ant/JSONExample.action",true);  
		   alert("Check whether Request is connected >>>>>>>" + request.connected);
		        var data = {  
		            		name:name.value
		            };
		           request.send(data);
		            alert("Check whether Request is connected AFTER SEND >>>>>>>" + request.connected);
			     request.onload = function(){  
		            	alret(" in Onload funtion ");
		                var json = Ti.JSON.parse(this.responseText);  
		                statusLabel.visible = true;
		                statusLabel.text = json;
		     }
		  } else {  
		            alert("Please enter description.");  
		    };  
		}); 

Entry in struts.xml is:

</action>
		  <action name="JSONExample" class="example.JSONExample" method="execute">
        	<result type="json"/>
     </action>

Do I need an interceptor in struts application to receive request from mobile application?What is the other way to call struts 2.0 application from a mobile application to receive JSON response? Looking from some help.Thanks in advance.
