<br>
Try with the extents of your mapfile in the maxExtent option:<br>
var bounds = new OpenLayers.Bounds(114.327181, 30.454108, 114.363140, 30.495525)<br>
map = new OpenLayers.Map( 'map', {maxExtent: bounds});<br>
<br>
Then after addLayer zoom on that extent:<br>
map.addLayer(layer);<br>
map.zoomToExtent(bounds);<br>
<br>
