Consuming Web Services

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

I will try not to make this a stupid question but I am on a project where just about everything is done in Java and there are no Perl people around to ask...

I have been asked to consume a SOAP web service that the java people are publishing (it's data from SAP for what it's worth). I am having a bit of trouble figuring out how to get started as there is no documentation. Here's what I know:

- I have a URL to a WSDL - There are some .xsd files

That's it! Can you help me to get started?

What I have tried so far is:

#!/usr/local/bin/perl -w
use SOAP::Lite;
$s = new SOAP::Lite -> service('https://myurl/services/BWReport');
[download]

which produces the crytic message:

junk after document element at line 2, column 0, byte 19 at /usr/local
+/lib/perl5/site_perl/5.8.3/sun4-solaris/XML/Parser.pm line 187
[download]

Any help you can provide would be greatly appreciated.

The output from changing this to have: `use SOAP::Lite +trace => 'all';` [download] will probably be enlightening. /J\	[reply] [d/l]

Now it produces: SOAP::Transport::new: () SOAP::Serializer::new: () SOAP::Deserializer::new: () SOAP::Parser::new: () SOAP::Lite::new: () SOAP::Deserializer::new: () SOAP::Parser::new: () SOAP::Schema::new: () SOAP::Deserializer::deserialize: () SOAP::Parser::decode: () junk after document element at line 2, column 0, byte 19 at /usr/local +/lib/perl5/site_perl/5.8.3/sun4-solaris/XML/Parser.pm line 187 SOAP::Schema::DESTROY: () SOAP::Deserializer::DESTROY: () SOAP::Lite::DESTROY: () SOAP::Deserializer::DESTROY: () SOAP::Parser::DESTROY: () SOAP::Transport::DESTROY: () SOAP::Serializer::DESTROY: () SOAP::Parser::DESTROY: () [download] Did that tell me anything useful? ~~~~~~~~~~~~~~~ I like chicken.

Look at `line 2, column 0, byte 19` of the WSDL file that you're trying to consume, because XML::Parser wasn't happy with it. If you need more info, try looking at `line 187` of the file `/usr/local/lib/perl5/site_perl/5.8.3/sun4-solaris/XML/Parser.pm`. Update: or as gellyfish pointed out indirectly, it might be unhappy with `line 2, column 0, byte 19` of the response from the SOAP message.	[reply]
