Populte List<ClassName> from JSON response and show in VF

Hello,

 

I need a bit help here;

My web service is returning JSON response, e.g..

{"feed":{"row_count":4,"items":[{"msg":"<a class='keyword' href='http://abc.html'>Click to view email1 </a> XXX
<a class='keyword' href='http://abc.html'>send email1</a>.","interestlevel":"High","date":"3/20/2012 10:29:30 PM"},{"msg":"<a class='keyword' href='xyz.html'>Click to view email2</a>XXX<a class='keyword' href='http://xyz.com'>send email2 3</a>.","interestlevel":"Medium","date":"3/20/2012 10:02:33 PM".....}]}}

 

My requirement is, perform formatting on each value of JSON response  (e.g. date, interestlevel values needs to be formatted individually) and send all values individually in one go.

 

I tried to achieve this using List<String>, but I was unable to perform value formatting as it was passing a single string.

What would be the best possible way to pass JSON response to VF pages?

 

I just want to show output in VF page like below;

 

Click to view email1 XXX send email1 updated on 20th March 2012 at 10:29 PM

Click to view email2 XXX send email2 updated on 20th March 2012 at 10:02 PM

.

.

.

Can we use functonality like List<ClassName> _objClass = new List<ClassName>();

public class ClassName{

  string msg;

  string interestlevel;

  datetime ddate;

}

but I was not able to achieve it.

 

How can I achieve the same in Apex and pass it to VF? sample code would be a great help!

 

Thanks in advance!!

Here is what I use. Then create this service instance in your controller and use the collection of entities however you want.

 

public class UserService {
	public UserService() {
		//
	}
	
	private HttpService httpService = new HttpService();
	
    public List<UserEntity> GetUsers() {
        HttpResponse res = this.httpService.GetHttpResponse('application/json', url);
        
        if (res.getStatusCode() != 200) { 
            System.debug('Error: ' + res.getStatusCode());
        } else {
            try {
                return (List<UserEntity>)Json.deserialize(res.getBody(), List<UserEntity>.class);
            } catch(Exception e) {
                System.debug('Exception: ' + e);
            }
        }
        
        return new List<UserEntity>();
    }
}

Thanks for reply.

I've used following code;

 

public List<clsLiveFeed> objLiveFeed {get; set;}

 

public class clsLiveFeed {
public string strMessage;
public string strInterest;
public DateTime dtWhen;
}

 

 livef.objLiveFeed = (List<clsLiveFeed>)JSON.deserialize(JSONContent, List<clsLiveFeed>.class);

but it is not converting JSON response to  List<clsLiveFeed>. Is there any specific reason?

Also, how do I bind the same to VF page?

 

below code is also not working;

<apex:dataTable value="{!objLiveFeed }" var="lf">
<apex:column value="{!lf}"/>
</apex:dataTable>

It does not show anything.. Am I missing somthing?

Thanks!
