Subject: Re: mod_jserv/5361: ServletRequest.getParameterValues() method does
not return multiple values
Date: Thu, 25 Nov 1999 05:29:56 -0800 (PST)
Hi,
In your Html file use hidden type of inputs to pass
the values to server.As well as you should use
different names in 'name' parameter(eg. movieid) in
checkbox type inputs.
And in your servlet program use getParameterNames()
function to get the all the names which are used in
input name of your html file.(No need to use
getReader() function). getParameterNames() values
should be assigned to Enumeration type variable.This
consists of all values along with names. To get the
values alone use getParameterValues("xxx") within
loop.
Here the sample html and servlet programs for you.
Its working fine.
sample.html
----------------
<html><head><title>Sample</title></head> <body>
<form action=/example/sample method=POST>
<input type=hidden name=sample value=sample>
<BR>Java<input type=checkbox name=ide
value=Java>
<BR>JavaApplets<input type=checkbox name=ide1
value=JavaApplets>
<BR>JaveServlets<input type=checkbox name=ide2
value=JavaServlets>
<BR><BR><input type=submit><input type=reset>
</form> </body></html>
*****************************
sample.java
---------------
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
public class sample extends HttpServlet
{
public void doPost(HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
//set the "content type" header of the
response
res.setContentType("text/html");
//Get the response's PrintWriter to return text to
the client.
PrintWriter toClient = res.getWriter();
Enumeration values =
req.getParameterNames();
while(values.hasMoreElements()) {
String name =
(String)values.nextElement();
String value = req.getParameterValues(name)[0];
if(name.compareTo("submit") != 0) {
toClient.println("<p>"+name+":
"+value);
}
}
// Close the writer; the response is done.
toClient.close();
}
}
All the best and Njoy with servlets.

>Description:
When a browser sends a request like the following one,
which is captured using getReader() method.
movieid=430&movieid=752&movieid=25&movieid=437&movieid=436&movieid=429&movieid=465&movieid=432&movieid=107&movieid=273&link=1.117.118.120
When I called
ServletRequest.getParameterValues("movieid"), I an
array with
only one value 430. I do not get all the values into
the array.
I know when I call
ServletRequest.getParameterValue("movieid"), I get one
value.
But the ServletRequest.getParameterValues, note the s
at the end, should give
me all the values packaged into the array.
Request:
I am developing a serious Web site. I will be very
thankful someone helping me on this.
