gmap.setCenter(new GLatLng(29.7598967, -95.3670557), 12);
........
locator = new esri.arcgis.gmaps.Locator("http://gisapps.houstongims.org/ArcGIS/rest/services/Address_Locator_Zip_Appr_HCAD_Parcel2009/Geocode...");
..........
var address = {
          Street:"611 Walker st",

Use Javascript Object instead of JavaScript Object Notation.

var address =new Object();
address.Street ="611 Walker st";
address.Zone ="77002";

locator.addressToLocations(address, callback); .....

Thanks Heming. But still no result shows after changing. I am wondering where the result markers come from for ESRI geocoder. Do I need to create marker for my geocoder? please see the source code:

You can get the geocoded point by using addressResults.addressCandidates[0].location.getLatLng(); and then signed the marker and add to the map.. Here is part of my code, hope it will help:
{
......
var locator = new esri.arcgis.gmaps.Locator(duvalGoogleApp.locatorDirectory);
   
    var address =new Object();
    address.Street =fmAddress;
    locator.addressToLocations(address, null, false, getToAddress);
}
function getToAddress(addressResults)
{
    if (addressResults.addressCandidates.length>0)
    {
         duvalGoogleApp.fPoint =addressResults.addressCandidates[0].location.getLatLng();
         .......   
     }
    else
    {
        duvalGoogleApp.Desc.innerHTML="Can not find the From address !";
        return;
    }
}
