Hi All,
Wonder if any of you guys can help troubleshoot the following for me.
What I’m trying to achieve is:
- Perl web service, using SOAP::Lite (server)
- Ruby web service consumer, using SOAP::RPC::DRIVER (client)
My problem is, if my client and server are both Perl based, the
output is as expected. However, if the client is Ruby based (haven’t
tried another language), it gets an error.
I have three files. Two on the server side and one on the client side.
Server Side
First, the script.
=== cgi script - located in c:/apache/cgi-bin/misc/
OdbcBridgeServer.pl ===
#!C:/perl/bin/perl.exe -w
use strict;
use SOAP::Transport::HTTP;
use OdbcBridgeServer;
my $name = shift;
SOAP::Transport::HTTP::CGI
→ dispatch_to(‘OdbcBridgeServer’)
→ handle;
=== end cgi script ===
Secondly, the Perl server side module (this is a cut down version).
=== module file - located in c:/perl/lib/OdbcBridgeServer.pm ===
package OdbcBridgeServer;
use DBI;
use strict;
sub new
{
my $type = shift(@);
my $class = ref($type) || $type;
my $self = {
class => $class,
sql => shift,
@
};
bless ($self, $class);
$self;
}
sub set_sql()
{
my $self = shift(@);
my $sql = shift(@) || “Select * from stock_master”;
return "" if !($sql =~ /^select/i);
$self->{sql} = $sql;
}
1;
=== end module file ===
Client Side
The third file is the client.
=== client script - on /Users/elinalaw/src/odbcBridgeClient.rb ===
require ‘soap/rpc/driver’
begin
ENDPOINT = ‘http://elina/cgi-bin/misc/OdbcBridgeServer.pl’
NAMESPACE = ‘http://elina/cgi-bin/misc/OdbcBridgeServer’
ob = SOAP::RPC::Driver.new(ENDPOINT, NAMESPACE)
ob.add_rpc_method(‘set_sql’, ‘a_string’)
rescue Exception => ex
puts “first block”
puts ex
end
begin
ob.call(“set_sql”, “select * from cre_master”)
rescue Exception => ex
puts “second block”
puts ex
end
=== end client script ===
When I run the programme, the output was:
=== start output ===
RubyMate r2903 running Ruby v1.8.3.
~/src/odbcBridgeClient.rb
second block
Failed to access class (cgi-bin::misc::OdbcBridgeServer) at C:/Perl/
site/lib/SOAP/Lite.pm line 2131.
Program exited normally.
=== end output ===
What’s the best way to find out what requests/responses are going
between the client and server?
Thanks all,
E
