Subject: Re: mod_jserv/5361: ServletRequest.getParameterValues() method does
not return multiple values
Date: Fri, 26 Nov 1999 06:30:01 -0800 (PST)
Hi,
There is no problem with JServ.
In your program, do like this:
...
...
String vals[] = req.getParameterValues("movieid");
...
And do array access like vals[0],vals[1],...
you will get all the values.
