[OpenLayers-Users] GetFeatureInfo problem

[Nguyen Le Minh]

Hi all, 
I install Geoserver 2.3.2 on Window OS. I write one 
HTML script which use openlayers to view my own layer also want to get 
information of my layer by GetfeatureInfo. I put this HTML file into HOME_GEOSERVER/data_dir/www. But currently I 
just viewed my layer. For getting information, it still not work. I 
though that it due to proxy problems. Could you help me to solve this problem? My main code is bellow: 
 
        <script src="http://localhost:8080/geoserver/openlayers/OpenLayers.js" type="text/javascript"> </script>        <script defer="defer" type="text/javascript">
            var map; 
            var untiled; 
            var tiled; 
            var pureCoverage = false; 
            // pink tile avoidance 
            OpenLayers.IMAGE_RELOAD_ATTEMPTS = 5; 
            // make OL compute scale according to WMS spec 
            OpenLayers.DOTS_PER_INCH = 25.4 / 0.28; 
        
            function init(){ 
                // if this is just a coverage or a group of them, disable a few items, 
                // and default to jpeg format 
                format = 'image/png'; 
                if(pureCoverage) {
