Question

I have a server (SoapUI) answering requests for a WSDL.

When sending test requests, my server code is receiving a list of arguments, but I’m trying to achieve is a single argument, of complex type, eg:

{
 ingredient_id   => INT
 something       => STRING
 ...
}

My types are as follow:

  <wsdl:types>
    <xsd:schema targetNamespace="/ingredient">
      <xsd:element name="getIngredientInfo" type="tns:IngredientRequest"></xsd:element>
      <xsd:element name="getIngredientInfoResponse" type="tns:ingredient"></xsd:element>

      <xsd:complexType name="ingredient">
        <xsd:sequence>
            <xsd:element name="ingredient_id" type="xsd:int" minOccurs="1" maxOccurs="1"></xsd:element>
            <xsd:element name="ingredient_name" type="xsd:string" minOccurs="1" maxOccurs="1"></xsd:element>
            <xsd:element name="status_gm" type="xsd:boolean" minOccurs="1" maxOccurs="1"></xsd:element>
            <xsd:element name="status_vegan" type="xsd:boolean" minOccurs="1" maxOccurs="1"></xsd:element>
            <xsd:element name="status_vegetarian" type="xsd:boolean" minOccurs="1" maxOccurs="1"></xsd:element>
            <xsd:element name="author_id" type="xsd:int" block="#all" minOccurs="1" maxOccurs="1"></xsd:element>
        </xsd:sequence>
      </xsd:complexType>

      <xsd:complexType name="IngredientRequest">
        <xsd:sequence>
            <xsd:element name="ingredient_id" type="xsd:int"></xsd:element>
            <xsd:element name="something" type="xsd:string"></xsd:element>
        </xsd:sequence>
      </xsd:complexType>

    </xsd:schema>
  </wsdl:types>

Can somebody help me to understand why WSDL is making SoapUI send the arguments as a list of simple arguments, instead of a single complex argument?

EDIT: It might be some problem with sequence tag, but I can’t find the issue in that, just need some light.
Thanks in advance!

Sure, I have it right here:

Still have no hints on it 🙁

Answer 1

You need to write your WSDL in “Document/literal wrapped”-style. These WSDL-styles are a bit confusing but here is a good comparison.

In essence you will need to wrap your complexType into an element:

<element name="IngredientInfo">
  <complexType>
    <sequence>
            <element name="ingredient_id" type="xsd:int"></xsd:element>
            <element name="something" type="xsd:string"></xsd:element>
    </sequence>
  </complexType>
</element>

and specify this element to be send as message

<message name="getIngredientInfoRequest">
    <part name="parameters" element="IngredientInfo"/>
</message>

Thus the resulting SOAP message contains this the IngredientInfo-element as the only child of the SOAP body:

<soap:envelope>
    <soap:body>
        <IngredientInfo>
            <ingredient_id>42</ingredient_id>
            <something>"What is..."</something>
        </IngredientInfo>
    </soap:body>
</soap:envelope>
