Graceful error handling in SOAP

jpfarmer has asked for the wisdom of the Perl Monks concerning the following question:

I am making use of several SOAP calls in one of our applications. However, I'm running into a problem gracefully trapping errors. We connect to the SOAP service using a call like this:

use SOAP::Lite                                                      
    service => 'https://someserver.com/wsdl/Method.wsdl',
    on_fault => sub { print Dumper(@_), "\n"; exit; };
[download]

The code works correctly, but the fault handling is ugly. Dumper returns a ton of information and I only need a bit of it (the faultcode and fault string), but I can't figure out how to get to it. If I just print @_ directly, I get the following object reference: SOAP::Lite=HASH(0xa341f00)

Most of the relevant pages I can find on the web deal with cases where the function call itself fails, but I can't find any examples on how to handle the error when the proxy setup fails.

Any help would be greatly appreciated.

It's described in the SOAP::Lite guide. In the example given: `-> on_fault(sub { my($soap, $res) = @_; die ref $res ? $res->faultstring : $soap->transport->status, +"\n"; })` [download] It'll die with the faultstring if there's an SOAP fault, or with the transport status if there wasn't a result object. (and in the case of a failed connection, it'll be a transport error, with no result object.)	[reply] [d/l]
