Hello and sorry again,
due to mailing problems, you did not recieve the whole message. Here
comes the third try
(this is not funny annymore. I reordered the contents of the mail,
since it seems, my mail-client is confused....)
I have a problem trying to transform a SOAPMessage using a
dom4j.DocumentResult
I do not have any problem to transform the SOAPMessage without dom4j
using xalan directly (CLI or via JAXP); however I am not an expert in
XSLT and maybe dom4j is more restrict?
Please find attached the soap message and the error focussed stylesheet.
Best regards,
Sven.
Here is the stacktrace:
javax.xml.transform.TransformerException: org.dom4j.IllegalAddException:
The node "org.dom4j.tree.DefaultElement@ef2c60 [Element: <t011_obj_data
attributes: []/>]" could not be added to the branch "null" because:
Cannot add another element to this Document as it already has a root
element of: t011_obj_data

Here is part of the code:
private void buildUDKEntity(SOAPMessage soapUDKQuery) {
try {
Source source = soapUDKQuery.getSOAPPart().getContent();
Result result = transformAttribute2Table(source);
....
Here the error happens:
private Result transformAttribute2Table(Source source) throws
TransformerException, TransformerConfigurationException,
FileNotFoundException {
Transformer transformer = getAttribute2TableTransformer();
// no problem here ...
//StreamResult result = new StreamResult(new StringWriter());
// ... but with DocumetResult
DocumentResult result = new DocumentResult();
transformer.transform(source, result);
return result;
}
