Hello,

Finally got it to work .

Made slight modifications to the existing code:

Struts Action:

1) Earlier was returning to an empty jsp page with no specific code. Now returning null.

2) Using the write method of the jsonObj to write the response data.

The action method now looks like the following:

public ActionForward getJSONData(ActionMapping mapping, ActionForm form,

JSP:

JSP Code to populate the grid is shown below:

$(document).ready(function(){
$.ajax(
    {
       type: “POST”,
       url:’  /TestJSON/testAction.do?method=getJSONData’,
       data: “”,
       dataType: “json”,
       success: function(result)
       {
            alert(“success”);
            alert(“result: ” + result.total);
            jQuery(“#list10”).jqGrid({
            url:’  /TestJSON/testAction.do?method=getJSONData’,
                datatype: ‘json’,
                mtype: ‘POST’,
                colNames:,
         colModel:[
             {name:’id’,index:’id’, id:’name’,width:90},
             {name:’invdate’,index:’invdate’, width:120},
             {name:’invname’,index:’invname’, width:200}
     ],
                pager: jQuery(‘#pager1’),
                rowNum: 5,
                rowList: [5, 10, 20, 50],
                viewrecords: true
            })
       },
       error: function(x, e)
       {
            alert(“errorddd ” + x.readyState + ” “+ x.status +” “+ e);
            if (x.readyState == 4) {
             var response = x.responseText;
             alert(response);
            }
       }
    });
setTimeout(function() {$(“#list10”).jqGrid(‘setGridParam’,{datatype:’json’}); },50);
