jQuery Grid Plugin - jqGrid

Hi  All;

I keep getting a parseerror when trying to load dynamic data from the server.  My server-side technology is JSP.  I create a simple .jsp file that looks like so:  So really the data is static.   The name of the file is  detailXml2.jsp

<?xml version ="1.0" encoding="utf-8"?>
<rows>
 <page>1</page>
   <total>2</total>
   <records>1</records>
   <row id ="1">
      <cell>detailXml4.jsp</cell>
      <cell>2007-10-06</cell>
      <cell>Client 3</cell>
      <cell>100.00</cell>
      <cell>0.00</cell>
      <cell>0.00</cell>
  </row>
</rows>

Here is my jqGrid definition

 $('#testGridTable').jqGrid(
    {
      height: 100,
      width:  950,
      url:'http://localhost:8080/FAMS/tes.....p&#39;,
      datatype: 'xml',
      mtype: 'GET',
      colNames:['Group','Sleeve', 'Account','Buy/Sell','Total','Notes'],
      colModel :[
        {name:'invid', index:'invid', width:55},
        {name:'invdate', index:'invdate', width:90},
        {name:'amount', index:'amount', width:80, align:'right'},
        {name:'tax', index:'tax', width:80, align:'right'},
        {name:'total', index:'total', width:80,align:'right'},
        {name:'note', index:'note', width:150, sortable:false} ],
      loadError: function(xhr,st,err) {
          alert("Error :" + st + "\\n" + xhr.responseText);
      },
      pager: jQuery('#testPager'),
                    rowNum:10,
                    rowList:[10,20,30],
                    sortname: 'id',
                    sortorder: 'desc',
                    viewrecords: true,
                    imgpath: 'scripts/jqgrid/themes/basic/images',
                    caption: 'This is the Test Grid'
    }
   ).navGrid('#testPager',{add:false,edit:false,del:false,refresh:false} );

This is the Error I keep getting.

Error:  parseerror

I know it is something very simple, because if I changed the name of the file to detail.xml it loads it without any problems. 

Thanks
