Hi,

I'd like to verify if there are any Parameters in servletData being passed into a doAction method. Is it just a matter of checking what getParameter or getParameters returns? Do these return NULL if they don't contain the Parameter(s)?


Thanks,

Jeremy

Jeremy, it's been a long time since I did these assignments, but I believe the answer to your first question is yes, but you have to do more than just "check" what is in the parameter. And I think the answer to the second question is also yes, because the parameters are strings, so if they aren't there then they would be null.
