I am using `jqGrid` to show data in tabular format, using `JSP` and `servlet`.

**EDIT**

I want to show errors from server, when operations like `insert, update, delete` are performed. `(datatype: "xml")`

**JQGrid**

```
jQuery("#list10_d").jqGrid({
                height:250,
                width:600,
                url:'Assignment?action=Assign',
                datatype: "xml",
                colNames:['Sr. No.','PID',  'DATE',  'EMPID'],
                colModel:[{name:'srNo',index:'srNo', width:30,sortable:false},
                           {name:'PID',index:'PID',width:0, sortable:true,editable:false},
                           {name:'DATE',index:'DATE', width:75,sortable:true,editable:true,editoptions: { dataInit: function(el) { setTimeout(function() { $(el).datepicker({dateFormat:"dd-M-yy",showButtonPanel: true,changeYear: true,changeMonth: true}).attr('readonly','readonly'); }, 200); }}},
                           {name:'EMPID',index:'EMPID', width:150,sortable:true,editable:true}
                           ],
                rowNum:10,
                rowList:[10,20,50,100],
                pager: '#pager10_d',
                sortname: 'PID',
                viewrecords: true,
                sortorder: "asc",

                    },
                multiselect: true,
                editurl: "Assignment?action=Edit",
                caption:"Assignment"
            } ).navGrid('#pager10_d',{edit:false,add:true,del:false,addtext:'Assign '},
                    {},
                    {modal:true,jqModal: false,closeOnEscape:true,savekey: [true,13],closeOnEscape:true, recreateForm: true,width:500,mtype:'POST', url: 'Assignment',editData:{action: 'Assign',PID: function () {return PID;}}, 
                afterSubmit: function (response) {
                        alert('After Submit \n' +'statusText: '+ response.statusText);
                        var myInfo = '<div class="ui-state-highlight ui-corner-all">'+
                                     '<span class="ui-icon ui-icon-info" ' +
                                         'style="float: left; margin-right: .3em;"></span>' +
                                     response.statusText + 'Inserted'+
                                     '</div>',
                             $infoTr = $("#TblGrid_" + $.jgrid.jqID(this.id) + ">tbody>tr.tinfo"),
                            $infoTd = $infoTr.children("td.topinfo"); 
                        $infoTd.html(myInfo);
                        $infoTr.show();

                        // display status message to 3 sec only
                        setTimeout(function () {
                            $infoTr.slideUp("slow");
                        }, 5000);

                        return [true, "", ""]; // response should be interpreted as successful
                    },
                    errorTextFormat: function (response) {
                    alert('Error Text Format: \n' +'statusText: '+ response.statusText);

                        return '<span class="ui-icon ui-icon-alert" ' +
                                     'style="float:left; margin-right:.3em;"></span>' +
                                    response.statusText;},
                    {closeOnEscape:true, recreateForm: true,mtype: 'POST',url: 'Assignment',delData: {action: 'Delete',PID: function () {return PID;}}},
                    {}) ;

```

**Servlet Code**

```
if(request.getParameter("action").equalsIgnoreCase("Assign"))
        {
            PID = request.getParameter("PID");
            String DATE= request.getParameter("DATE");
            String EMPID= request.getParameter("EMPID");

            String query = "insert into ASSIGN(PID,DATE,EMPID) values('"+ PID +"','"+ DATE +"','"+ EMPID"')";
            boolean b = insert.InsertData(query);
            if(b)
            {
                System.out.println("New record added successfully! : "+query);
                response.setContentType("text/xml");
                response.setCharacterEncoding("UTF-8");

                //response.sendError(200, "success");
                response.setStatus(200, "Inserted successfully");

            }
            else
            {
                System.out.println("Failed to add Record! : "+query);
                response.setContentType("text/xml");
                response.setCharacterEncoding("UTF-8");

                //response.sendError(399, "not Inserted successfully");   
                response.setStatus(404, "Error while inserting");   
            }           
        }//INSERT

```

for above example 

* after `inserting` record from jqgrid, then `No message is shown` in
grid if record is `inserted successfully`
* `error Status: 'Unauthorized'. Error code: 401` is shown if servlet fails to insert record in database.

My Question is that: 

* after `inserting` record from jqgrid, if the record is inserted then how should i show message giving information to user that data is inserted.
* and how should I give message to user that `Error while inserting` (which `error code` should i use for this?)

Thanks in advance.....
