Sending page via WCTP -- Internal Server Error -- Ewe

[jabdulius]

Hi all,

I'm trying to send a page using Perl via the WCTP protocol. For some reason, I cannot connect to the host "wctp.att.net/WCTP" (or any host for that matter). I figure it must be some server configuration that I need to set. I don't think it's a port problem b/c I'm able to send a page via WCTP using the same port using a stand-alone app.

Anyhow, here's the code I'm using:

sub send_wctp_old{
    #my $url = "http://wctp.cingular.com:80/WCTP";
    my $url = "http://wctp.att.net/WCTP";
    print "TestEPaging::send_wctp_old()--Sending via WCTP to " . $url . " <BR>";
 
    my $body = "<?xml version=\"1.0\"?><!DOCTYPE wctp-Operation SYSTEM \"http://www.skytel.com/protocols/dtds/wctp/wctpv1-0.dtd\">";
    $body = $body . "<wctp-Operation wctpVersion=\"WCTP-DTD-1.1\"><wctp-SubmitClientMessage><wctp-SubmitClientHeader>";
    $body = $body . "<wctp-ClientOriginator senderID=\"";
    $body = $body . $from;
    $body = $body . "\"/><wctp-Recipient recipientID=\"";
    $body = $body . $to;
    $body = $body . "\"/></wctp-SubmitClientHeader><wctp-Payload><wctp-Alphanumeric>";
    $body = $body . $message;
    $body = $body . "</wctp-Alphanumeric></wctp-Payload></wctp-SubmitClientMessage></wctp-Operation>";
 
    #my $ua = LWP::UserAgent->new;
    my $ua=new LWP::UserAgent;
    my $header=new HTTP::Headers;
    print "TestEPaging::send_wctp_old()--Created new UserAgent<BR>";
 
    #my $http_response = $ua->request(POST $url, Content_Type => 'text/xml', Content => $body);    
 
    my $req = new HTTP::Request ("POST", $url, $header, Content => $body );
 
    my $http_response=$ua->request($req);
 
    print "TestEPaging::send_wctp_old()--Sent request<BR>";
 
    if ($http_response->is_success){
        print "TestEPaging::send_wctp_old()--Message sent successfully to " . $to;
    }
    else{
        print "TestEPaging::send_wctp_old()--Message failed - " . $http_response->as_string;
    }
}

And here's the error output I'm seeing:
TestEpaging::main()--to=4255333734
TestEpaging::main()--from=1111111111
TestEpaging::main()--message=Hello
TestEpaging::main()--protocol=WCTP

TestEPaging::send_wctp_old()--Sending via WCTP to http://wctp.att.net/WCTP
TestEPaging::send_wctp_old()--Created new UserAgent
TestEPaging::send_wctp_old()--Sent request
TestEPaging::send_wctp_old()--Message failed - 500 Can't connect to wctp.att.net:80 (connect: Unknown error) Content-Type: text/plain Client-Date: Thu, 28 Jun 2007 16:35:30 GMT Client-Warning: Internal response 500 Can't connect to wctp.att.net:80 (connect: Unknown error)

Any advice is much appreciated.
Thanks!

Do you normally send data to WCPT via "POST" method?

I just want to point out that a lot cleaner way of composing your message would be the following:

    my $body = <<END;
<?xml version="1.0"?><!DOCTYPE wctp-Operation SYSTEM "http://www.skytel.com/protocols/dtds/wctp/wctpv1-0.dtd">
<wctp-Operation wctpVersion="WCTP-DTD-1.1"><wctp-SubmitClientMessage>
<wctp-SubmitClientHeader>
    <wctp-ClientOriginator senderID="$from"/>
    <wctp-Recipient recipientID="$to"/>
</wctp-SubmitClientHeader>
<wctp-Payload>
    <wctp-Alphanumeric>$message</wctp-Alphanumeric>
</wctp-Payload>
</wctp-SubmitClientMessage></wctp-Operation>
END
