Linux install: SOAP

Installing the packages for SOAP

The Simple Object Access Protocol (SOAP, also known as Service Oriented Access Protocol) is a way to remotely make method calls upon classes and objects that exist on a remote server.

SOAP lite

The SOAP::Lite collection of Perl modules provides a simple and lightweight interface to SOAP.

Emerge SOAP::Lite

emerge search soap
emerge -f SOAP-Lite
emerge SOAP-Lite

The downloaded components are:
libnet-1.16.tar.gz, MailTools-1.60.tar.gz, MIME-Base64-3.00.tar.gz, IO-stringy-2.108.tar.gz, Digest-1.05.tar.gz, Digest-MD5-2.33.tar.gz, Crypt-SSLeay-0.49.tar.gz, URI-1.28.tar.gz, HTML-Tagset-3.03.tar.gz, HTML-Parser-3.28.tar.gz, libwww-perl-5.69.tar.gz, MIME-tools-5.411a.tar.gz, MIME-Lite-3.01.tar.gz, SOAP-Lite-0.55.tar.gz

SOAP server

SOAP is based on the HTTP protocol. You will need to have a running HTTP server on the SOAP server machine.

Writing a SOAP server CGI is described in SOAP Quick Start Guide. Let's take the hiBye example:

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

use SOAP::Transport::HTTP;
SOAP::Transport::HTTP::CGI
  -> dispatch_to('Demo')
  -> handle;

package Demo;
sub hi {
  return "hello, world";
}
sub bye {
  return "goodbye, cruel world";
}
sub languages {
  return ("Perl", "C", "sh");
}

SOAP client

The SOAP client is:

#!perl -w
  use SOAP::Lite;
  print SOAP::Lite
    -> uri('http://www.soaplite.com/Demo')
    -> proxy('http://serverAddress/serverPath/hiBye.pl')
    -> hi()
    -> result;
