Hi!
I’m currently building a simple request-response style webservice using
SOAP4R and describing it in WSDL, so that it can easily be used from multiple
langages.
I was wondering how best I should describe the exceptions my methods will be
raising. First, I defined two compexType’s that look like what SOAP4R actually
throws.
wsdl:types
<xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"
targetNamespace=“http://fakeroot.net/webservice/rbg/ver1/”>
</xsd:schema>
</wsdl:types>
and then, defined each of them as a message.
<wsdl:message name=“authentication_ERROR” >
<wsdl:part name=“exception” type=“tns:AuthenticationError” />
</wsdl:message>
<wsdl:message name=“authorization_ERROR” >
<wsdl:part name=“exception” type=“tns:AuthorizationError” />
</wsdl:message>
Finally I bound the two messages to my operation with the element
<wsdl:portType name=“FooService”>
<wsdl:operation name=“dosomething”>
<wsdl:input message=“tns:dosomething_IN” />
<wsdl:output message=“tns:dosomething_OUT” />
<wsdl:fault message=“tns:authentication_ERROR” />
<wsdl:fault message=“tns:authorization_ERROR” />
</wsdl:operation>
</wsdl:portType>
The AuthenticationError and AuthorizationError classdefs are generated according
to the type-definition (naturally, similart to Ruby’s Exception class) but
using the XML-code above, only AuthorizationError inherits from StandardError,
AuthenticationError doesn’t. If I swap the two tags above, only
AuthorizationError inherits but AuthenticationError doesn’t.
Looking at SOAP4R 1.5.0’s wsdl/operation.rb, it seems that it only supports
one fault per operation, overriding earlier s with later occuring ones
in WSDL::Operation#parse_element().
But the WSDL 1.1 schema states that an can have multiple .
…

…
A bug in SOAP4R 1.5.0 ? Or I might be misunderstanding something.
Or is there any recommended/proper way to declare the exceptions that
my SOAP4R-service will raise in WSDL, in a langage-independent way ?
