I'd do this part a bit more like this:
Enumeration parameters = req.getParameterNames();
while(parameters.hasMoreElements())
{
String parameter = (String) parameters.nextElement();
if (parameter.startsWith("d-"))
{
page = request.getParameter(parameter);
break;
}
}
try
{
startPage = Integer.parseInt(page);
}
catch (NumberFormatException ex)
{
startPage = 1;
}

Overall, not really, no. You need to get the parameter and deal with it.
The one thing I'd add is that "d-" parameters are displaytag parameters,
meaning that it's not exclusively the page. It could also indicate sort
order and other display parameters. I think there's a guide to the
various parameter formats around so that you can determine which is which,
but I don't remember where I saw that or if someone posted it to this list
or what.
