SOAP Server package World; sub new { bless {}, shift; }; sub HelloWorld { my ($self) = @_; return "Hello World\n"; }; 1; use SOAP::Transport::HTTP; use World; SOAP::Transport::HTTP::CGI   -> dispatch_to('World')   -> handle; SOAP Client use SOAP::Lite; my $s = SOAP::Lite    ->uri('World')    ->proxy('http://soapserver. mycompany.com/soap/soapserver.cgi')    ->HelloWorld(); print $s->result(); 11/28/2018 Web Services in Perl

SOAP Request XML Document that consists of an envelope, header & body <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/1999/XMLSchema"> <SOAP-ENV:Body> <namesp1:HelloWorld xmlns:namesp1="World"/> </SOAP-ENV:Body> </SOAP-ENV:Envelope> 11/28/2018 Web Services in Perl

Conclusion Web Services Perl Foundation for a paradigm shift in the internet Integration of applications regardless of languages or platforms Perl Best suited for building internet applications Ideal for text extraction using regular expressions 11/28/2018 Web Services in Perl
