//Attach a controller to the browser field		mBrowserField.getConfig().setProperty(BrowserFieldConfig.CONTROLLER, new BrowserController());


//Define actions to be done on URL calls
final class BrowserController extends ProtocolController{

private String URL_TO_TRAP = "http://us.blackberry.com/devices.html";		

     //Called when navigating to a new URL	
   public void handleNavigationRequest(BrowserFieldRequest request) throws Exception{
			
			if(request.getURL().equals(URL_TO_TRAP) ){
                               //custom action here
                         }

			super.handleNavigationRequest(request);		
     }
		
    //Called when the browser field is loading a resource(image, script etc)
    public InputConnection handleResourceRequest(BrowserFieldRequest request) throws Exception{
		
                        if(request.getURL().equals(URL_TO_TRAP) ){
                               //custom action here
                         }
			return super.handleResourceRequest(request);
     }		
}

You need to attach a controller to the browserfield and check every URL that is called. 

It is advisable to use "indexOf()" String comparison instead of equals to avoid clash with parameters within URL. 

e.g., you want to trap call to "http://us.blackberry.com/devices.html" but the actual call could be "http://us.blackberry.com/devices.html?lid=us:bb:devices&lpos=us:bb:devices"

Tell me this solved your problem!

thanx. I tried this with BrowserFieldListener. I got my solution.

BrowserFieldListener events are called AFTER/DURING the Page is loaded. It might cause errors if you delete the screen that contains the BrowserField on loading a URL. Using a controller is a better approach if this is what you are doing since those methods are called before a URL is requested.

i used it in documentCreated() method.
