[OpenLayers-Users] Format ajax.request

[Dan Koch]

Greetings,
I'm having trouble formatting my openlayers.ajax.request. I have the
following:

var queryStr = 
'?request=GetFeature&version=1.0.0&service=wfs&typeName=massgis:GISDATA.TOWNS_POLY';

sendTestRequest(queryStr);
	   
function sendTestRequest(queryStr) { 
	var uri = "http://giswebservices.massgis.state.ma.us/geoserver/wfs";	
	var request = new OpenLayers.Ajax.Request(uri, 
		{method: 'get', 
		parameters:queryStr,
		contentType:'text/xml', 
		onComplete: function(){},
		onFailure: function(){alert("an error occured")}
		}
	); 
} 

I get the following response via firebug:

<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport version="1.0.0"
  xsi:schemaLocation="http://www.opengis.net/ows
http://giswebservices.massgis.state.ma.us:80/geoserver/schemas/ows/1.0.0/owsExceptionReport.xsd"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ows="http://www.opengis.net/ows">
  <ows:Exception exceptionCode="MissingParameterValue" locator="request">
    <ows:ExceptionText>Could not determine geoserver request
      from http request
org.apache.catalina.connector.RequestFacade at d39fe</ows:ExceptionText>
  </ows:Exception>
</ows:ExceptionReport>


Any help would be greatly appreciated,
Dan
