4 easy steps to start Perl CGI programming on Windows in 10 seconds or less
1. Download Active Perl and install it.
2. Download Apache for Windows and install it.
03/19/2011 01:11 PM 25,704,148 ActivePerl-5.12.3.1204-MSWin32-x86-294330.msi

2 File(s) 31,104,724 bytes
(now start counting those 10 seconds)
3. Go to
C:\Program Files\Apache Software Foundation\Apache2.2\cgi-bin
and create test.cgi file with the following contents
#!C:\perl\bin\perl.exe -wT
use strict;
use CGI;
my $query = new CGI;
print $query->header( "text/html" );
print <<END_HERE;
<html>
<head>
<title>My First CGI Script</title>
</head>
<body bgcolor="#FFFFCC">
<h1>This is a pretty lame Web page</h1>
<p>Who is this Ovid guy, anyway?</p>
</body>
</html>
END_HERE
(make sure to hit "enter" a couple of times after END_HERE, otherwise it won't work)
4. Open
http://localhost/cgi-bin/test.cgi
in the browser. Enjoy.
Thanks to PerlMonks.org for the article.
P.S. PerlTutorial.org gives a bit more consequent example:
#!C:\perl\bin\perl.exe -wTRead more...
# It's always a good idea to use the strict pragma while developing
# Perl code, it makes Perl warn about dangerous code
use strict;
# We're also going to include the CGI module, so that we can take
# advantage of other programmer's efforts (One of Larry Wall's basic
# tennants is that programmers are fundamentally lazy -- he's probably
# right, but I can't be bothered to prove it right now)
use CGI;
# instantiate a new CGI object
my $cgi = new CGI;
# perform a single print statement, with liberal use of the perl
# string concatenator "." and some CGI methods
$cgi->header .
$cgi->start_html('Hello World!') .
$cgi->h1('Hello World!') .
$cgi->end_html;
# Tell the web server everything is fine
exit (0);

[WARN] [rms ] javacall_file_open: _wopen failed for: ... _delete_notify.dat
If, while trying to launch your midlet in an emulator, you see a message like
, know that you are not alone.
People keep desperately asking the same question without any luck.
At least sometimes it helps to just brutally create the missing "_delete_notify.dat", and the emulator starts to execute the midlet as if nothing happenned. Read more...
