I think all the servlet engines will handle this identically... they'll
see that the method of the form was "POST", and consequently look to the
post data rather than the querystring for any parameters. I suppose you
could have all servlets check both the querystring and post data, but
this seems like extra processing for something that isn't very
frequently used.
Here are 2 solutions
:
1. Call javax.servlet.http.HttpUtils.parseQueryString
(request.getQueryString ());
This will return a Hashtable of the query string parameters. Then for
post data you'd use the standard request.getParameter (""), and for
query string data, you'd use this hashtable. This is probably your best
bet.
2. Include any query string parameters as hidden elements in your form.
Change your html from what you have below to:
<form method="post" action="response.jsp">
<input type="hidden" name="name" value="value">
<input type="submit" value="Hello">
</form>
I think the better is more elegant, but I remembering running into
situations where that just isn't practical. Hope these suggestions
help.
