Problems while developing a Perl client

Question

Hi,
I am trying to interface to the OCWS using SOAP through Perl.
Here is the code:
#!/usr/bin/perl
use strict;
use LWP::UserAgent;
use HTTP::Request;
my $ua = LWP::UserAgent->new(env_proxy => 1, keep_alive => 1, timeout => 30, );
my $data_to_send;#-- And build a string of it
open(SOAPREQ,"soap_req.soap");
while(<SOAPREQ>) {
$data_to_send = "$data_to_send$_";
print "Sending :\n$data_to_send\n";
#-- Create the Request Object and send the data
my $response =
$ua->request(HTTP::Request->new('POST', 'http://development-10.cc.uic.edu/ocws-bin/ocas.fcgi',
HTTP::Headers->new('Content-Type' => 'text/xml', 'SOAPAction' => 'http://www.oracle.com/WebServices/Calen\
daring/1.0/'), $data_to_send));
#-- Print the response
print $response->as_string;
Note that I have my SOAP payload in the soap_req.soap file. This is a simple Ping command. Here is the listing:
<?xml version='1.0' encoding='UTF-8'?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<cwsl:Ping xmlns:cwsl=
"http://www.oracle.com/WebServices/Calendaring/1.0/">
</cwsl:Ping>
</soap:Body>
</soap:Envelope>
But, this doesn't seem to work. (I realise that I have not set the Content-Length SOAP header in the Perl code. If this could be the source of the problem, would someone please tell me whether the Content-Length includes the length of the headers also or just the payload).
The listing for the response in SOAP indicates a "method name not supported error". Here is the listing for the response:

Would greatly appreciate any help with this.
Thanks.

Hi,
We are actually trying to test Calendar WebServices on a fresh OCS Release 2 installation, with Testoraptor (!), but unsuccessfully ...
So, I tried you Perl script, and I have the same problem :
Sending :
<?xml version='1.0' encoding='UTF-8'?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<cwsl:Ping xmlns:cwsl="http://www.oracle.com/WebServices/Calendaring/1.0/">
</cwsl:Ping>
</soap:Body>
</soap:Envelope>
HTTP/1.1 500 Internal Server Error

And into a browser, the URL "http://<machine>:<port>/ocws-bin/ocas.fcgi" give us the message :
500 Internal Error
Could you help us ?
Thank's,
