how to, JSON data

[Pradeep Adibatla]

I have a hashMap ,HMap1 which contains 3 values...

How to prepare this as JSON and use it in jsp??

This statement tells me that I have 1 value in my map
!!!

   System.out.println("The val is :--> "+atrHMap1.toString().trim());   

I did like this...

 
                  JSONObject jsonObject  = JSONObject.fromObject( atrHMap1 );
                  System.out.println("The array Vals are :--> "+jsonObject );
 

I use the plugin jsonplugin-0.32.jar...

This jar should be ok or something else should be used??

It doesn't print anything?? what could it be? and how do I use this in my Javascript...

I converted like this,it worked with a different plugin though...

   
JSONObject json = new JSONObject(atrHMap1);

                 String out=json.toString();

                 System.out.println("out is :--> "+out);
 

Now in JS I have...

  
 if(xmlhttp.readyState==4)
     {
          alert(xmlhttp.responseText);
        
//         json 'out' to be used...



           var selectBox = document.getElementById('act');  //id of the select box
          
        alert("select box is :--> "+selectBox);

          selectBox.innerHTML = xmlhttp.responseText;   // I want that 'out' into this selectBox !!!


  

how do I use that json string in the above code??


I also have this in struts.xml

 
 <package name="default" extends="json-default" >
       <action name="cules" class="CulesModelAction" >
          <result type="json">
             <param name="root">jsonData</param>
          </result>
       </action>
   </package>
   

Though it is struts2 ,the core issue lies with JS and hence the post here... thanks!
