SOAP::Lite Quickstart demo Use of uninitialized value in pattern match (m//)

[philosophia]

I'm trying to run the SOAP::Lite Quickstart demo at

http://guide.soaplite.com/#quick%20start%20guide%20with%20soap%20and%20soap::lit\ e

My hibye.pl looks like

#!/usr/bin/perl -w

# -- SOAP::Lite -- guide.soaplite.com -- Copyright (C) 2001 Paul
Kulchenko --

use SOAP::Lite;
print SOAP::Lite
-> uri('http://server.com/cgi-bin/soaplite/Demo')
-> proxy('http://server.com/cgi-bin/soaplite/hibye.cgi')
-> hi()
-> result;

-I'm getting a 500 internal server error when I try to run the script. hibye.cgi has not been modified except the path to perl.

My machine is ubuntu dapper drake, with apache2 and SOAP::Lite installed. My apache2 error logs look like

#this gives me the following in my error log

[Fri Jul 07 16:15:39 2006] [error] [client 1.1.1.1] Use of
uninitialized value in pattern match
(m//) at /usr/local/share/perl/5.8.7/SOAP/Transport/HTTP.pm line 411.
[Fri Jul 07 16:15:39 2006] [error] [client 1.1.1.1] Premature end of
script headers: hibye.pl

I've tried googling that error, but couldn't find a way to fix it.

Any advice appreciated.

Your script doesn't send out CGI headers, so it shouldn't be run as a CGI. Try running it from the command line.

As an aside, please read Writeup Formatting Tips. Your post is very hard to read.

update: are you actually using the right URL? I.e. I doubt you're running http://server.com, so check if you're using the right URL to call the SOAP server.

I get the same message in my apache2 error log when I try to run it from the command line
perl hibye.pl


[Mon Jul 10 14:15:11 2006] [error] [client 128.135.0.88] Use of uninit

The URL seems ok. the only thing I changed is the domain name.

[Joost]

That message is not necessarily a problem - though it might indicate something is wrong. Does the script give any normal output when you do that?

You can turn on SOAP::Lite debugging using

use SOAP::Lite +trace => [qw/ debug method fault /];

which may help you track down the issue

I'm getting the following output with debugging:

does this mean my uri line is wrong? I'm not sure what would be the correct uri value.

[philosophia]

one other thing is that the quickstart files also contain a file called 'Demo.pm' - which is in the same directory



package Demo;

# -- SOAP::Lite -- guide.soaplite.com -- Copyright (C) 2001 Paul Kulch
+enko --

sub hi {
  return "hello, world";
}

sub bye {
  return "goodbye, cruel world";
}

sub languages {
  return ("Perl", "C", "sh");
}

1;

so if hibye.pl's uri parameter is looking for a .pm called 'Demo' in the soaplite directory, it is there.

Try to turn off warnings, i.e. remove the -w switch from the shebang line.

Does the error Premature end of script headers: hibye.pl still appear in the log?

[philosophia]

yes I still receive the same message in the logs even when I remove -w
