HTML form processing in perl

I have one HTML form:
<html>
<head>
<title>Greetings</title>
</head>
<body>
<form action="greeting.pl" method="post">

Please enter your name:

<input type="text" name="name" maxlength="30">
<input type="submit" value="Submit">
</form>
</body>
</html>

I want to display the name via perl script.
I wrote the following

use strict;
use warnings;
use CGI;
my $q = CGI->new;
my $name = $q->param('name');
print "$name";

But not working. Error:
Server error!
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.

Please help

partial Interface implemention

I have one interface with three(more than one) method declaration.
In the subclass that implements it I want to define only one method not all three not even blank definition of them.Is there any keyword or method for that.
How to do it? Is it possible to do it?

In GUI we use adapter classes to achieve it. What for console application?
