I find I have a few places in my code that look like this:
String path =
StaticWebUtils.addParameterToURL(forward.getPath(),"uid","12345");
forward = new ActionForward(path,true); // Create new ActionForward with
appropriate params added to path
(the method it uses just determines whether to use ? or &)
public static String addParameterToURL(String url, String parameter, String
value)
{
return url + ( (url.indexOf("?")==-1) ? "?" : "&" ) + parameter + "=" +
value;
}
I too wonder if there is a better way of doing this.

Where $1 would be replaced with the toString() value of the first object
that is bound to the ActionForward using .bind(Object ojb)
