Re: Using request.getParameterValues

[Chen, Gin]

Hi Milt,
        Sorry about the ill worded post. After failing to send back multiple
values for the parameter (later found on it was a script error in my hidden
field creation javascript). I was trying to fake mulitple parameters by
setting one param's value to:
        "paramvalue&param=paramvalue&param=paramvalue"
I was hoping that it would send it as
http://myurl/app/destination?param=paramvalue&param=paramvalue&param=paramva
lue
But apparently it's not that simple. :-P hehe

Maybe I'm misunderstanding what you're trying to do, but I believe
this all should be handled automatically, regardless of the http
method (i.e. GET or POST).  Multiple values for parameters is
perfectly normal stuff, and the built-in API method
(getParameterValues) should handle getting multiple values by default.
Here's the javadoc for that method:

http://java.sun.com/products/servlet/2.3/javadoc/javax/servlet/ServletReques
t.html#getParameterValues(java.lang.String)

It returns an array of String's, all the values of the specified
parameter name.

AFAIK, this all has been solved since the very early versions of the
spec.
