With Tapestry 4.1 you would inject the WebRequest object and call 
getParameterValue() on it (see 
http://tapestry.apache.org/tapestry4.1/apidocs/org/apache/tapestry/web/WebRequest.html).
To inject the WebRequest use

@InjectObject("infrastructure:request")
public abstract WebRequest getRequest();

in your page class.

Cheers,

Uli
