How to unmarshall XML code containing @XmlAnyEleme

Question

I am trying to handle soap response from a webservice. I have used wsimport tool to generate client class for handling soap response. Below are the sample soap response and java handler.

Soap Response :

<?xml version="1.0" encoding="UTF-8"?>
<DataSet xmlns="http://tempuri.org/">
  <xs:schema id="NewDataSet" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
    <xs:element name="NewDataSet" msdata:IsDataSet="true" msdata:UseCurrentLocale="true">
      <xs:complexType>
        <xs:choice minOccurs="0" maxOccurs="unbounded">
          <xs:element name="NTIS">
            <xs:complexType>
              <xs:sequence>
                <xs:element name="Error" type="xs:string" minOccurs="0"/>
              </xs:sequence>
            </xs:complexType>
          </xs:element>
        </xs:choice>
      </xs:complexType>
    </xs:element>
  </xs:schema>
  <diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1">
    <NewDataSet xmlns="">
      <NTIS diffgr:id="NTIS1" msdata:rowOrder="0" diffgr:hasChanges="inserted">
        <Error>UserName and/or Password are invalid.</Error>
      </NTIS>
    </NewDataSet>
  </diffgr:diffgram>
</DataSet>

Client program :

package org.ritwik.client;

import java.util.List;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Unmarshaller;
import javax.xml.soap.Node;

import org.tempuri.BACOnlineResponse;
import org.tempuri.BACOnlineResponse.BACOnlineResult;

import org.tempuri.GetUserInfoResponse;
import org.tempuri.GetUserInfoResponse.GetUserInfoResult;
import org.tempuri.IsUserValidResponse;
import org.tempuri.ObjectFactory;
import org.w3c.dom.Element;

public class WsClient {

        /**
         * @param args
         * @throws JAXBException 
         */
        public static void main(String[] args)  {
            // TODO Auto-generated method stub

            Deawebsvc deaw=new Deawebsvc();
            DeawebsvcSoap impl=deaw.getDeawebsvcSoap();
            ObjectFactory of=new ObjectFactory();   
            DEAAppSearchResponse dsSearch=of.createDEAAppSearchResponse();
            dsSearch.setDEAAppSearchResult(impl.deaAppSearch("[e-mail]"," deavalidation", "dea", "bac", "basc", "expirationFrom", "expirationTo", "company", "zip", "state", "pi", "maxRows"));
            System.out.println(dsSearch.getDEAAppSearchResult().toString());
            System.out.println(dsSearch.getDEAAppSearchResult().getAny());



        }

    }

Now the problem is I am unable to handle Result conet from "getDEAAppSearchResult().getAny()". Please suggest how to handle the content or unmarshal this.

org.tempuri.DEAAppSearchResponse$DEAAppSearchResult@7bc768 [diffgr:diffgram: null]

Answer 1

I had a similar problem, I used an Unmarshaller to unmarshal the detailed node to a meaningful object. In my problem, the detailed classes were generated (NewDataSet in your example). The following may work for you:

JAXBContext jaxbContext = JAXBContext.newInstance(NewDataSet.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
Node node = (Node) dsSearch.getDEAAppSearchResult().getAny();
NewDataSet dataset = (NewDataSet)unmarshaller.unmarshal(node.getFirstChild());
