David,
You could use HttpUtils.parseQueryString, but the entire class is
deprecated. I like your home made parser below, with a couple of tweaks:

If there's no '?' in the URL, then you can return false right away, right?

This uses a regular expression which is relatively slow since you
already know what you're looking for.
How about this implementation:
public boolean isParamInUrl(String url, String paramName)
{
~ return url.contains('?' + paramName + '=')
~ || url.contains('&' + paramName + '=');
}
This looks simpler, easier to read, and less error-prone. I would
venture a guess that it runs faster than your implementation, too. I
could increase the speed a bit by using StringBuilder directly instead
of allowing the compiler to write code for me, but that would make it
more difficult to read.
Enjoy,
