Spring WS JAXB CDATA issue

[Mat Anthony]

Hi All,
I'm trying to write some code that will handle CDATA issues wen Marshalling data (i.e. org.sport.vo.GetTennisDetailsResponse)
I currently have the following configuration:-
<!-- uses JAXB annotations to marshall between XML messages and Java objects --> <bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="classesToBeBound"> <list> <value>org.sport.vo.GetTennisDetailsRequest</value> <value>org.sport.vo.GetTennisDetailsResponse</value> </list> </property> </bean>

I have searched the internet and found the following example that uses class CdataJaxb2Marshaller that extends Jaxb2Marshaller
The example uses String[] cdataElements, that is spring injected in, but I need to use GetTennisDetailsResponse

Here is the example

<bean id="marshaller" class="org.springbyexample.marshaller.CdataJaxb2Marshaller">
  <property name="cdataElements">
  <list>
    <value>^value</value>
  </list>
</property>


import java.io.IOException;
import java.io.OutputStream;

import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.transform.Result;
import javax.xml.transform.stream.StreamResult;

import org.apache.commons.lang.ArrayUtils;
import org.springframework.oxm.MarshallingFailureException;
import org.springframework.oxm.XmlMappingException;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.oxm.mime.MimeContainer;


public class CdataJaxb2Marshaller extends Jaxb2Marshaller 
{

  private String[] cdataElements;
  public String[] getCdataElements() 
  {
    return cdataElements;
  }
  public void setCdataElements(String[] cdataElements) 
  {
    this.cdataElements = cdataElements;
  }


  //Data that will be sent out object to xml
  @Override
  public void marshal(Object graph, Result result, MimeContainer mimeContainer) throws XmlMappingException 
  {
    if (ArrayUtils.isNotEmpty(cdataElements)) 
    {
      try 
      {
        Marshaller marshaller = createMarshaller();

        com.sun.org.apache.xml.internal.serialize.XMLSerializer serializer = 
        createXMLSerializer(cdataElements, ((StreamResult)result).getOutputStream());

        marshaller.marshal(graph, serializer.asContentHandler());

     } 
     catch (IOException e) 
     {
       throw new MarshallingFailureException(e.getMessage(), e);
     } 
     catch (JAXBException ex) 
     {
       throw convertJaxbException(ex);
     }
   } 
   else 
   {
     super.marshal(graph, result);
   }
  }

@SuppressWarnings("restriction")
private com.sun.org.apache.xml.internal.serialize.XMLSerializer createXMLSerializer(String[] cDataElements, OutputStream cOut) 
{
   // This code is from a sample online: http://jaxb.java.net/faq/JaxbCDATASample.java
   // configure an OutputFormat to handle CDATA
   com.sun.org.apache.xml.internal.serialize.OutputFormat of = new com.sun.org.apache.xml.internal.serialize.OutputFormat();

  // specify which of your elements you want to be handled as CDATA.
  // The use of the '^' between the namespaceURI and the localname
  // seems to be an implementation detail of the xerces code.
  // When processing xml that doesn't use namespaces, simply omit the
  // namespace prefix as shown in the third CDataElement below.
  of.setCDataElements(cDataElements); //

  // set any other options you'd like
  of.setPreserveSpace(true);
  of.setIndenting(true);
  of.setPreserveSpace(false);

  // create the serializer
  com.sun.org.apache.xml.internal.serialize.XMLSerializer serializer = new com.sun.org.apache.xml.internal.serialize.XMLSerializer(of);
  serializer.setOutputByteStream(cOut);

  return serializer;
}

}

Can anybody help.

Hi All,
I think all I have to do to this is
<bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="classesToBeBound"> <list> <value>org.sport.vo.GetTennisDetailsRequest</value> <value>org.sport.vo.GetTennisDetailsResponse</value> </list> </property> <property name="cdataElements"> <list> <value>^specification</value> </list> </property> </bean>

I think that this then searches the the response object (i.e. GetTennisDetailsResponse) that has been converted into xml via jaxb for
a tag named specification. I think that this then uses the specification tag to be handled as CDATA.
Please can somebody confirm that if this is correct.

Hi All,
I'm currently getting the following error:-
java.lang.ClassCastException: org.springframework.ws.soap.axiom.AxiomResult
on calling:-

com.sun.org.apache.xml.internal.serialize.XMLSerializer serializer =    
createXMLSerializer(cdataElements, ((StreamResult)result).getOutputStream());   

It looks like you cannot cast the result (i.e. javax.xml.transform.Result) to OutputStream

StreamResult streamResult =((StreamResult)result);
OutputStream cOut=streamResult.getOutputStream();
XMLSerializer serializer = createXMLSerializer(cdataElements, cOut);

Can anybody help?

Hi All,
I have still got a problem with trying to marshall data using CDATA with spring ws and jaxb.
I have tried the above approach, but I cant get it to work?
