UTF-16 encoded return value

Hi,

we are using axis 1.2.1 on tomcat 5.x. Some of our services return an utf-16
encoded xml string. We have set the parameter "axis.xmlEncoding" in the
server-config.wsdd to "UTF-16", but when building the soap message, axis
throws an exception:

Client receives something like that:
java.lang.IllegalArgumentException: The char '0x0' in
'java.lang.IllegalArgumentException: The char '0x0' in 'ÿþ&lt;
...

The stacktrace in a testcase:
at org.apache.axis.components.encoding.AbstractXMLEncoder.encode
(AbstractXMLEncoder.java:110)
at org.apache.axis.utils.XMLUtils.xmlEncodeString(XMLUtils.java:131)
at org.apache.axis.utils.DOM2Writer.normalize(DOM2Writer.java:344)
at org.apache.axis.utils.DOM2Writer.print(DOM2Writer.java:246)
at org.apache.axis.utils.DOM2Writer.print(DOM2Writer.java:208)

at org.apache.axis.utils.DOM2Writer.nodeToString(DOM2Writer.java:49)
at org.apache.axis.utils.XMLUtils.privateElementToString(XMLUtils.java:433)
at org.apache.axis.utils.XMLUtils.ElementToString(XMLUtils.java:442)
at org.apache.axis.utils.XMLUtils.getInnerXMLString(XMLUtils.java:542)

To transform our xml to utf-16 we use the following:
...
TransformerFactory trafoFactory = TransformerFactory.newInstance();
transformer = trafoFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.INDENT, "no");
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-16");
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC, "no");
transformer.setOutputProperty(OutputKeys.CDATA_SECTION_ELEMENTS, "no");
transformer.transform(new DOMSource(doc), new StreamResult(out)); 
...

We use the transformer from java.xml.transform and the document buider from
java.xml.parsers

Is there anything I can do to force axis to accept our utf-16 xml string or
is there a different possibility? The fact is we need utf-16.

Thanks,

Ronny Weiser
