iw_cgi_wrapper.cgi and perl problem

Okay I've been working with Teamsite for a bit and have managed to do quite well on my own and by browsing these forums. There is one issue I hit that is getting to me a bit.

Here are my specifics:
Teamsite 6.5 - SP2
Windows 2000 Server - SP4

In my DCT, I have a function that is executed on "onSaveDone" and it's calling a Perl file to do some stuff in the background. To start off and make sure I had things right, I created a simple perl program that creates a file (the file is stored in /httpd/iw-bin. It's called "createFile.ipl"

Here is the perl code within the file:
-----------------------
#!E:\iw-home/iw-perl/bin/iwperl
open SAVELOG, ">>e:\onSave.log";
print SAVELOG "WORKED\n";
close (SAVELOG);
-----------------------

I ran it from the command line using the IWperl (it's in my path) and it works fine (file is created).

Now in my function within my DCT, I make perform a callServer and everything appears to run fine - I get no error coming back but the file that is supposed to be created in the perl script does not get created. I put in an alert after the "callServer" and it doesn't get executed so things seem to be hanging at that line. the DCR is created by the the DCT screen does not get refreshed (so the file name does not appear even though the file has been created).
Function code:

var server = window.location.hostname;
var params = new Object();
callServer("http://"+server+"/iw-bin/iw_cgi_wrapper.cgi/createFile.ipl", params, true);

Am I suffering from a case of the Friday stupids or am I way off base here?

Suggestions?
cheers!

Simple question first: Is your script, createFile.ipl, in IWHOME/httpd/iw-bin ?

Hello,

Yes the file is is IWHOME/httpd/iw-bin. I forgot put in the IWHOME part.

Thanks

Probably one of those simple-but-maddeningly-hard-to-see problems - it looks right to me, sorry.

Try IWDatacapture.callServer(...);

Okay I popped that in and my alert after the callServer is showing up now but I'm getting an error message. It says:

"TeamSite: Wrapper
Error: CGI startup error: CONTENT_LENGTH=0"

Am I supposed to be returning something? The show_env.ipl works with the iw_cgi_wrapper just fine and I noticed that it returns the HTML.

/Thanks

try adding .exe to end of your first line, this was an issue that popped up in 6.5. Support indicated that I change this and then they all worked.

#!E:\iw-home/iw-perl/bin/iwperl.exe

FurnaceFace

With uncontainable enthusiasm, I typed in the "exe" you had pointed out. I thought to myself "This is it.. i can go home for a beer now"...

But alas....

that did not do it. I'm still getting the error about CONTENT_LENGTH=0

Thanks

Try putting someting into the params object?

Johnny

Are you getting this error message from the apache error log?

What happens when you type that URL directly into the browser?

Have you tried sending some output back - maybe that's the problem.. it's expecting a response.

At the end of your script put this

print "Content-type: text/html\n\n";

Not sure if this will help. Here is a section from the FORMAPI and the perl file that we are currently using to get file details of attached files. You might see something that works to fix your problem. Also, we're not using a cgi wrapper file with this. Calls the ipl file directly.


function runFileName(file,name,path1,path2)
{
var server = window.location.hostname;
var params = new Object();
params.fileName = file;
params.fileObjectName = name;
params.path1 = path1;
params.path2 = path2;
IWDatacapture.displayMessage("Getting file data ...");
top.hiddenFrameRunning = true;
IWDatacapture.callServer("http://"+server+"/iw-bin/custom/production/formapi/shared/filedata.ipl", params);
}


#!e:\iw-home/iw-perl/bin/iwperl.exe -w

#This returns the file size, type, and download time for attachments

use CGI;
use Teamsite::Config;

#Turn buffering off.
$| = 1;

my${cgi} = new CGI();
my $file = ${cgi}->param('fileName');
my $fileObjectName = ${cgi}->param('fileObjectName');
my $path1 =  ${cgi}->param('path1');
my $path2 =  ${cgi}->param('path2');

print "Content-type: text/html\n\n";

my $path = "y:\\\\default\\\\main\\\\".$path1."\\\\WORKAREA\\\\".$path2;
my $fullfile = $path.$file;
 $fullfile =~ s|/|\\\\|g; 
  #$fullfile =~ s|\\app16||g;

  my $extension = substr($fullfile,-3,3);

  my $size = -s $fullfile;
  my $bytes = $size;
  my $finsize = "";
  my $fex = "";
  my $isSpaces = "false";

  if($size < 1024)
  {$fex = "Bytes"}
  else
   {
    if($fileObjectName eq '/fileNameFr')
    {
     $fex = "Ko"; 
    }
  else
    {
     $fex = "Kb";
    }

    $size = int($size / 1024)
   }

  if($size > 1000)

   {$fex = "Mb";
   $size = $size / 1000;
   $size = sprintf("%.1f",abs($size))}

  $finsize = ($size . " " . $fex);



print <


<script language="javascript">
    var finSize ='$finsize';
    var fileObjectName ='$fileObjectName';
    var fileType = '$extension';
    var bytes = '$bytes';
    // Set up the options object for a locations.
    $location
</script>

To Taalgaard and others..

THANK YOU for all your help - most appreciated!

The solution to this little mindbender was twofold.

1) I got rid of the cgi-wrapper and called the perl file directrly with my callServer method

var server = window.location.hostname;
IWDatacapture.callServer("http://"+server+"/iw-bin/createAltLanguage.ipl");

2) My perl code was missing a "\" on the open SAVELOG line (after the "e:\")

The correct code is then

-----------------------
#!E:\iw-home/iw-perl/bin/iwperl
open SAVELOG, ">>e:\\onSave.log";
print SAVELOG "WORKED\n";
close (SAVELOG);
-----------------------

Thanks again to those who chimed in to help and for those who shared your code insights!

Ah - 20/20 hindsite - the iw_cgi_wrapper.cgi probably isn't working because credentials aren't getting passed through from the FormAPI code on the client to the CGI script being called on the server.

With regard to the pathing issue - I highly recommend you always use forward-slashes (/) instead of back-slashes (\) - because it's portable *and* avoids the kind of problem you just ran into.

Thanks Ghoti - good point.

Btw - are you at GearUp? if so, how was Cirque du Soleil? Smiley Happy

Yes - I'm at GearUp.
Cirque du Soleil is tonight - and I imagine it will be excellent as all their shows are (I've seen three of their shows in Las Vegas [one twice], and two of their travelling shows in Pittsburgh)

I am at GearUP. The presos have been good. A lot of Worksite stuff, so it looks like IW has a real winner there. Some new TS functionality coming out looks promising.

Having seen Cirque before, this was Cirque-Lite, 2 clowns, a Hula-Hoop girl, juggler, and 2 acrobats. They were all top notch (and the Hula-hoop girl was staring at me all show, I swear Smiley Very Happy

), but it was still 6 people for about 45 minutes.
