ServletRequest.getParameter question

[Steve]

Hi,

I'm using ServletRequest. getParameter(), but how do I tell the difference a
parameter in the query part of a URL and a posted parameter (e.g. an input
field of a form where method="post").

Is there anything like the PHP equivalent of $_GET[] and $_POST[] which can
differentiate between parameters in a URL and posted parameters.

Thanks very much.

PS. I'm using the J2EE 1.4 API

look at the doGet and doPost methods-
do either one and have it call the other one - passing the request and
response object

That's what I thought initially, but what if I POST the url
'/webapp/servlet?param=v alue'

There is no way (AFAICT) to tell whether 'param' was in the URL or a posted
parameter?

Sure you can - just do a request.getMeth od()... if its GET then you know
it was on the command line, if its POST, then you know it was posted.
You can also double check by parsing the URL and making sure that
variable was not in it...

That last check is dangerous: What if it were located in both?

The first bit I agree with - if the request method is GET, then obviously
there can be no body to the request so all params must be from the URL.

But, as I said what if I POST the url '/webapp/servlet?param=v alue'
Take the following HTML form for example:


<form method="post" action="/webapp/servlet?param1= value1">
<input type="hidden" name="param2" value="value2"/>
</form>

So tell me - what methods are available to indicate param1 was from the URL
and param2 was not.

I'd rather not re-invent the wheel if I don't have to.
