Try JSTS. It integrates very well with OpenLayers and contains the
Buffer-function client side in javascript. That means it works on
features in a vector-layer. I'm not sure if that is what you're
looking for though.<br>

<div>Hi,</div>
<div><br>
</div>
<div> I need to implement a "simple" buffer tool. The tool
should simply place a Buffer zone around the position clicked
in the map when the tool is activated.</div>
<div><br>
</div>
<div>...the tool should work like this...</div>
<div><br>
</div>
<div>1. Activate tool in toolbar</div>
<div>2. Set Radius in map units </div>
<div>3. Click in map </div>
<div>4. buffer polygon based on the set radius is created and
rendered in the map</div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>My system is Geoserver 2.1.2 / Postgis 1.5</div>
<div><br>
</div>
<div>I have done this with an sld and also in postgis ...but I
really need the real-time effect in the map!</div>
<div><br>
</div>
<div>any help or examples would be great,</div>
