UTFDataFormatException when executing transform on soapMessage content

[Marko Tekavc]

I want to transform soap message I get from webservice call to pretty printed xml string (using javax.xml.transformer.Transformer). I have this method:

 public static String sourceToXMLString(Source src) {
        String xmlResult = null;
        try {
            TransformerFactory factory = TransformerFactory.newInstance();
            Transformer transformer = factory.newTransformer();
            transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
            transformer.setOutputProperty(OutputKeys.STANDALONE, "yes");
            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            transformer.setOutputProperty(OutputKeys.METHOD, "xml");
            transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
            StreamResult streamResult = new StreamResult();
            streamResult.setOutputStream(new ByteArrayOutputStream());
            transformer.transform(src, streamResult);
            xmlResult = streamResult.getOutputStream().toString();
        } catch (TransformerException e) {
            e.printStackTrace();
        }
        return xmlResult;
    }

I get java.xml.transform.Source object from calling web service (I don't have direct control on soap response):

                         ...
           SOAPMessage responseMessage = dispatch.invoke(requestMessage);
           String prettyPrintString = sourceToXMLString(responseMessage.getSOAPPart().getContent());
                                  ...

This code works just fine on my test server (Glassfish V2) but it throws exception in line (transformer.transform(src, streamResult)) on BEA Weblogic Server:

javax.xml.transform.TransformerException: java.io.UTFDataFormatException: Invalid byte 1 of 1-byte UTF-8 sequence.
        at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl.transform(TransformerImpl.java:654)
        at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerImpl.transform(TransformerImpl.java:281)

How can I properly transform soapMessage with javax.xml.transformer?

The same exact error - Invalid byte 1 of 1-byte UTF-8 sequence is looked at XML and Invalid byte UTF-8.
