Hi Lorenzo

                Thank you very much for the help. I have a question. Is there a way I can directly get the bounding box values for a layer using WMS Manager APIs. Because the reason I want to do WMS GetCapabilities is to get this info only. If WMS GetCapabilities is the only way then I am not sure how to do it using WMS Manager. Can you show me with an example ( making a WMS GetCapabilities to a WMS server request and after parsing the received XML ). Any help is highly appreciated

Thanks in advance

Hi Ganesh,
I've made an external module for OpenLayers that does what you want (maybe).
The name is WMS Manager [1].
There's a blog post that explain how to use it in the easy way [2].
there's a live application the shows it working [3].

The code is not that clean but inside the WMS Manager Control there are 
a few tricks to make GetCapabilities work smoothly with Mapserver and 
Geoserver, and some other WMS servers. Not all vendors are supported. I 
consider this code still in Beta phase; I'm still developing new 
features that I need for my project.

I'll be available for further explanations.
