Adding namespace doens't work

Question

Hi,
I need to add the namespace to a IDOC. It seens to, that XI doesn't add the namespace for IDOC.
To do that I implement a java mapping like this :
public void execute(InputStream in, OutputStream out)
          throws StreamTransformationException {
                    Document source = null; // Source message
          String sourceString = null; // Source XML message as a string
          // Create out of the InputStream the Source XML document
          try {
               DocumentBuilderFactory factory =
                    DocumentBuilderFactory.newInstance();
               source = factory.newDocumentBuilder().parse(in);
               // Add namespace to document
               Element root = source.getDocumentElement();
               String messageNamespace = null;
               messageNamespace = (String)param.get(StreamTransformationConstants.INTERFACE_NAMESPACE);
               root.setAttribute("xmlns",messageNamespace);
During runtime the result of this mapping ist the following :
<?xml version="1.0" encoding="utf-8"?>
<ORDERS05 xmlns="urn:sap-com:document:sap:idoc:messages">
<IDOC xmlns="" BEGIN="1">
<......
Why the mappingruntime add the xmlns="" in the IDOC tag ?
Any hints ?

Hello Gerald,
We'd the same problem here. Actually R3 didn't put a namespace inside the IDOC XML format.  I opened a message some months ago. Here the answer from SAP:
+"...XML namespaces are a part of the XML syntax as attributes and elements.
Some XML documents will use them and others not. (The same as some XML
documents will contain attributes and others not). When XML namespaces
are used the syntax is with these xmlns- resp. xmlns:
In this case unfortunately there exists no BAdI or a user exit. So the
only way I see is a modification of the standard.
Within Include "LEDI7F04" there is a paragraph
Idoctyp immer
    CLEAR OUT_STRING.
    IF EDIDC-IDOCTP CA '_'. " enthält mind. ein _
      CONCATENATE START_CONTROL_IDOCTYP CDATA_START_TAG EDIDC-IDOCTP
                  CDATA_END_TAG END_CONTROL_IDOCTYP
                  INTO OUT_STRING.
    ELSE.
      CONCATENATE START_CONTROL_IDOCTYP EDIDC-IDOCTP END_CONTROL_IDOCTYP
                  INTO OUT_STRING.
    ENDIF.
This builds the "" for your scenario.
As the coding is different for Unicode and Non-Unicode, you have to
make such a coding modification for the Unicode case within Include
"LEDI7F05" in the following paragraph:
idoctyp immer
    concatenate i_string start_control_idoctyp edidc-idoctp
                           end_control_idoctyp into i_string.
  [within form "control_record_xml"]
As there is a BAdI for the Unicode case, I recommend to use the BAdI
instead of a modification.
Hope that this information could help you!!
