If wsdl:part have "type" attribute and haven't "element" attribute, give error message.

[chenyu468]

For example,

<wsdl:message name="getLibSysCodeResponse">
<wsdl:part name="getLibSysCode" type="xsd:string" />
</wsdl:message>

LocalPart = erlsom_lib:localName(Element), <---- throw here.

I have changed soap_parse_wsdl.erl as follows, still have error.

type_for_message(#'wsdl:definitions'{message = Messages}, Message, Model) ->
    case lists:keyfind(Message, #'wsdl:message'.name, Messages) of
        false ->
            {error, "Message " ++ Message ++ " not found"};
        #'wsdl:message'{part = Parts} when length(Parts) /= 1 ->
            {error, "Message " ++ Message ++ " does not have exactly 1 part"};
        A = #'wsdl:message'{part = [#'wsdl:part'{element = Element,type=Type}]} ->
            %% what we need is the type
            lager:debug("_381:~n\t~p",[A]),
            case Element of
                undefined ->
                    Type;
                _ ->
                    LocalPart = erlsom_lib:localName(Element),
                    Uri = erlsom_lib:getUriFromQname(Element),
                    Prefix = erlsom_lib:getPrefixFromModel(Model, Uri),
                    Element_name = case Prefix of 
                                       undefined ->
                                           LocalPart;
                                       "" ->
                                           LocalPart;
                                       _ -> 
                                           Prefix ++ ":" ++ LocalPart
                                   end,
                    type_for_element(list_to_atom(Element_name), Model)                    
            end
    end.

Can you share your WSDL/XSD privately or post a cut down version which demonstrates the problem please?

I tried to modify the soap_parse_wsdl.erl,

• 'wsdl:message'{part = [#'wsdl:part'{element = Element,type=Type}]} ->

     case Element of
         undefined ->

• Type;
• case Type of
• {qname,"http://www.w3.org/2001/XMLSchema","string","xsd","xsd"} ->
• ""; _ ->
• Type
• end;
• _ ->
• %% what we need is the type

[willemdj]

The "rpc" binding style is currently not properly supported.

I'll try to fix it, but I think it will not be a trivial task. It will probably take some time to get this work done.

[willemdj]

After taking a closer look at the complete WSDL example that was provided I noticed that this WSDL uses the "rpc/encoded" style. This style is not supported, since it is not part of WS-I basic profile.

Even if I manage to make the rpc style work, it will only be in combination with the "literal" encoding style (rpc/literal, which is part of WS-I basic profile). So this particular WSDL will still not be acceptable.

[cmullaparthi]

@chenyu468 Please see if the latest changes in #6 help you by changing the WSDL style to rpc/literal. If not, there is not much we can do I'm afraid.
