SOAPMessage.writeTo() - No line breaks

Hi All

In the SAAJ API there is the SOAPMessage.writeTo(java.io.OutputStream). This writes out the XML of the SOAP message, BUT with NO line breaks.

Does anyone know of / have a convenient method WHICH INCLUDES line braeks
and indents - so you see the XML in it's normal form ??

Cheers Eddy

Forgot to add
Or if there is some configuration that can be done ....

Cheers Eddy

You could capture the OutputStream, and run it through an XML pretty-printer, such as the ones that are part of Xerces or XOM.

Ok thanks Ulf, I'll check that out, Eddy

Hi guys, having the same problem.
Is there any standard solution now for this (noticed the topic is from 2005...)?
I need to save the content of the SoapMessage simply as String, not some other fancy format.

But it has to match EXACTLY the content of the soap response (also indents and line breaks)
because it contains a digital signature and the validation of the signed document fails if some parts are edited

Thanks in advance for any help!!! It's kind of urgent

Hi!

Before the calculation of any digital signature of XML data, the data must be canonicalized, that is the XML data must be transformed to a standardized form.

Regarding your question:
You can use a XSLT transform to write XML to a file, below follows an example:

/** 
     * Reads an XML document into a DOM and using XSLT, writes a 
     * part of the DOM to the console. 
     * 
     * @throws Exception If error occurs reading XML document. 
     */ 
    public void doWritePartXMLExample() throws Exception 
    { 
        DOMExample theDOMReader = new DOMExample(); 
        Document theDOM; 
        /* Use DOM to read the document. */ 
        theDOM = theDOMReader.readXMLDocument(KOMPIS_XML_FILE_NAME); 
        /* Get the XSLT transformer factory and create a new transformer. */ 
        TransformerFactory theXFormFactory = TransformerFactory.newInstance(); 
        Transformer theXFormer = theXFormFactory.newTransformer(); 
        /* 
         * Configure transformer to produce: 
         * - Indented output. 
         * - A standalone document. 
         */ 
        theXFormer.setOutputProperty(OutputKeys.INDENT, "yes"); 
        theXFormer.setOutputProperty(OutputKeys.STANDALONE, "yes"); 
        /* 
         * Create a source and result for the transformer. 
         * Note that a node in the DOM is selected to be the root 
         * of the XML document to be output. 
         */ 
        Node thePersonNode = 
            theDOM.getElementsByTagName(PERSON_ELEMENT_NAME).item(0); 
        DOMSource theDOMSrc = new DOMSource(thePersonNode); 
        StreamResult theResult = new StreamResult(System.out); 
        /* Do the transform. */ 
        theXFormer.transform(theDOMSrc, theResult); 
    }

Hi thanks for your prompt answer
The problem is not how to write the stuff in an xml file
the problem is how to take the content of a SOAPMessage object and put it into a string
when I do soapMessage.writeTo(myByteArrayOutputStream)
the byteArrayOutputStream doesn't contain the same white spaces and line breaks as the original one.
I'm gonna read the documents about the canonicalization you sent me now, thanks

@Ivan, Thank you for that very helpful code example.

@Glittery Lally: After some searching based on Ivan's example, I found another link that may have exactly what you need: SOAP message handler for logging inbound SOAP results. I just tried it and it worked fine for me. Its the same as Ivan's example, except that it reads the XML from the soap message instead of from a file. Hope that helps.

@R Srini: Thanks a lot for your message and your time.
I tried your code and it works but unfortunately I have the same problem.
Some line breaks are lost

So I have to try another solution.

I used : http://javakafunda.blogspot.in/2012/04/how-to-format-xml-string-in-java.html

and it worked for me...
