Unmarshall SOAP Message using JAXB

Question

when i unrmarshall below SOAP message, i am getting exception. Can someone tell me what is wrong?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/" xmlns:hios="http://schemas.datacontract.org/2004/07/HIOSCommonObjects">
   <soapenv:Header/>
   <soapenv:Body>
      <tem:ValidIssuersProducts>
         <!--Optional:-->
         <tem:li>
            <!--Zero or more repetitions:-->
            <hios:IssuerProductRequest>
               <!--Optional:-->
               <hios:Issuer>33104</hios:Issuer>
               <!--Optional:-->
               <hios:Product>33104VA001</hios:Product>
            </hios:IssuerProductRequest>
         </tem:li>
      </tem:ValidIssuersProducts>
   </soapenv:Body>
</soapenv:Envelope>

Unmarshalling code is as below, clazz is "fully qualified name of ValidIssuersProducts" request.

public static <T> Object unmarshall(String xml, String clazz) throws ClassNotFoundException, JAXBException {
        JAXBContext context = JAXBContext.newInstance(Class.forName(clazz));
        ByteArrayInputStream input = new ByteArrayInputStream (xml.getBytes());     
        Unmarshaller unmarshaller = context.createUnmarshaller();   
        //JAXBElement<ValidIssuersProducts> obj = (JAXBElement<ValidIssuersProducts>) unmarshaller.unmarshal(new StreamSource(input), ValidIssuersProducts.class);

        ValidIssuersProducts value = (ValidIssuersProducts)unmarshaller.unmarshal(input);
        return  value;

    }

I am getting below exception:

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Envelope"). Expected elements are <{http://tempuri.org/}ArrayOfIssuerProductRequest>,<{http://tempuri.org/}ArrayOfIssuerProductResponse>,<{http://tempuri.org/}IssuerProductRequest>,<{http://tempuri.org/}IssuerProductResponse>,<{http://tempuri.org/}ValidIssuersProducts>,<{http://tempuri.org/}ValidIssuersProductsResponse>

Answer 1

You need to unmarshal from the nested element ValidIssuersProducts which corresponds to your mapped content instead of the SOAP Envelope element. You can use a StAX XMLStreamReader to parse the XML and advance to the correct element and then unmarshal from the `XMLStreamReader at that point.
