Why not just write your own variation?
String getParm(HttpServletRequest req, String name)
{
return(getParm(req, name, ""));
}
String getParm(HttpServletRequest req, String name, String defValue)
{
String s = req.getParameterValue(name);
if (null == s)
s = defValue;
return(s);
}
Then just pass in the default value you want:
String postParam = getParm(req, "postParm", "0");
