Getting Marshall result into String

Question

JAXBContext context = JAXBContext
                    .newInstance(CreateExemptionCertificate.class);
            Marshaller m = context.createMarshaller();
            m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);

            m.marshal(cc, System.out);

In the code above i am getting the result to the console (I mean XML is getting printed on the console). I want to get this XML to a string. I am not getting which argument I should pass to the marshal method to get XML String in a String variable instead of printing it on the console. Anybody having any idea please share.

You can do it like this :

CreateExemptionCertificate cc = ...;
JAXBContext context = JAXBContext.newInstance(CreateExemptionCertificate.class);
Marshaller m = context.createMarshaller();
m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

StringWriter sw = new StringWriter();
m.marshal(cc, sw);

String result = sw.toString();

Just now I have got the answer of my question from this post below:

I want to convert an output stream into String object

I need to use StringWriter to take XML String from Marshal method

Try marshalling to an instance of ByteArrayOutputStream and then invoking toByteArray on it.

What do you want to do with it? The approach I proposed (calling `toByteArray()` on the stream) would give you a `byte[]` instance containing the bytes of the XML. – laz Feb 06 '12 at 06:08
Im having the same need, in my case I'm trying to returning it as a result of service call. – code4jhon Nov 10 '13 at 21:09

This is the parser I use for convert an object to string using jaxb library.

 JAXBElement<Foo> jaxbElement = new JAXBElement<>(
                new QName(Foo.class.getSimpleName()), Foo.class, request);
        JAXBContext contextRS = JAXBContext.newInstance(Foo.class);
        String requestXml = lhParser.marshalAndConvertToString(jaxbElement, contextRS);


//converter

    public String marshalAndConvertToString(JAXBElement jaxbElement, JAXBContext context) {
        try {
            StringWriter writer = new StringWriter();
            context.createMarshaller().marshal(jaxbElement, writer);
            String s = writer.toString();
            LOG.info(" ------------------------ xml \n{}",s );
            return s;
        } catch (JAXBException e) {
            e.printStackTrace();
        }
        return null;
    }
