Re: RPC::XML::Client question

You could use the Data::Dumper module to inspect the returned $result structure.

use Data::Dumper;

...
my $result = $client->send_request...;
print Dumper($result);

But that's just the problem. $result = ''; It is defined, but still very much so empty... It's not even a reference :-(

[Roger]

Did you check if the $client is built properly? You could add another print Dumper($client);. I just think the line my $client = RPC::XML::Client->new('http://localhost:8000/'); looks doggy, don't you need to specify the name of the service in the URL? Something like 'http://localhost:8000/cgi-bin/rpcserver'.

And you could also invoke the perl debugger and step into the send_request method, and see step by step what is happenning inside the module. Are you on Linux? If so, you could just invoke the ddd visual debugger by specifying -perl on the commandline, together with the name of your script.

using DDD is a good one - thanks! I still don't get it though...

Where does it go wrong? Beats me...
