Hi,
I am calling a webservice through HTTP callout and trying to parsing the data and showing that in Visualforce page.
when i am debuging the list is returning value however when i am trying to show it through VF nothing is comming.Please help.
My VisualForce page :
<apex:page controller="FirstHTTP" sidebar="false">
<apex:Form >
<apex:pageBlock title="Contact Details">
<apex:PageBlockTable value="{!spp}" var="b">
<apex:column value="{!b.sconlist}" headervalue="Id"/>
<apex:column value="{!b.snamelist}" headervalue="Name"/>

</apex:PageBlockTable>
</apex:pageBlock>
</apex:Form>
</apex:page>


Controller Class :
public class FirstHTTP {
    // Public Wrapper1 swrapper1;
  Public FirstHTTP()
  {
      HTTPRequest s = New HTTPRequest();
      S.setEndpoint('https://api.androidhive.info/contacts/');
      s.setMethod('GET');
      
      HTTP H1 = new HTTP();
      HTTPResponse Resp =H1.send(s);
      string sresponse =Resp.getBody();
     // System.debug(sresponse);
     // swrapper1 = new list<wrapper1>();
      list<String> sid = new list<String>();
       JSONParser parser = JSON.createParser(sresponse);
        while (parser.nextToken() != null) {
            if ((parser.getCurrentToken() == JSONToken.FIELD_NAME) && 
                (parser.getText() == 'id')) {
                // Get the value.
                parser.nextToken();
               sid.add(parser.getText());
                // Compute the grand total price for all invoices.
              // system.debug(sid); 
                
            }
        }
       list<String> sname = new list<String>();
      JSONParser parser1 = JSON.createParser(sresponse);
        while (parser1.nextToken() != null) {
            if ((parser1.getCurrentToken() == JSONToken.FIELD_NAME) && 
                (parser1.getText() == 'name')) {
                // Get the value.
                parser1.nextToken();
               sname.add(parser1.getText());
                // Compute the grand total price for all invoices.
              // system.debug(sid); 
                
            }
        }
     list<wrapper1> spp = new list<wrapper1>();
     // system.debug(Sid.size());
      for(integer i=0;i<Sid.size();i++)
      {
          swrapper1 = new Wrapper1();
          swrapper1.sconlist = sid[i];
          swrapper1.snamelist = sname[i];
          spp.add(swrapper1);
         // system.debug(slist);
      }
     // system.debug(slist);
      
  }
    public list<Wrapper1> spp{set;get;}
    public Wrapper1 swrapper1{set;get;}
    public class Wrapper1{
        public string sconlist{set;get;} 
            public string snamelist{set;get;}
    }
