Hi,<br><br>if you just want to get the features in browser memory (that is, get them into a JavaScript variable) you can fetch them issuing an XHR to GeoServer rather than using a Vector layer that your map will not display at all (BTW, if you finally use that approach be sure that you use OpenLayers.Strategy.Fixed if you want to load all features - using BBOX will load only those in the map viewport). Note that this way you are just issuing a request to a server, there is nothing specifically related to WFS, features, GIS or anything. You can then use a Format.WFS to parse the features.<br>
<br>OpenLayers provides some facilities to perform cross-browser XHR. It would be, for example:<br><br>var processResponse = function(response) {<br> // Do your stuff here, typically with response.responseText, something like <br>
// var features = new OpenLayers.Format.WFS().read(response.responseText);<br> // I didn't test it !!<br>}<br>OpenLayers.Request.issue({<br> url: '<a href="http://localhost:8081/geoserver/wfs">http://localhost:8081/geoserver/wfs</a>',<br>
method: 'GET',<br> params: {<br> service: 'WFS',<br> version: '1.0.0',<br> request: 'GetFeature',<br> typeName: 'MyMap:MyLayer',<br> success: processResponse<br> }<br>

<p>One final thing before I sleep. The following query (typed directly into the browser) returns the layer's features:</p>
<pre><blockquote>
<a href="http://localhost:8081/geoserver/wfs?service=wfs&version=1.1.0&request=GetFeature&typeName=MyMap:MyLayer" target="_blank">http://localhost:8081/geoserver/wfs?service=wfs&version=1.1.0&request=GetFeature&typeName=MyMap:MyLayer</a>
</blockquote>
</pre>
<p>Executing the query above returns the following:</p>

<p>So, executing the query directly to the map server (i.e., GeoServer) works. What is the equivalent "new OpenLayers.Layer.Vector" call and the corresponding "featureType" and "featureNS"?</p>
