WebServiceTemplate suppressed empty xmlns-Attribut (xmlns="") in SOAP-Message

[omueller]

Hello,

I have a xml-message with a default namespace on top of the message and
an empty xmlns-Attribut some elements deeper in the structure

e.g.
<root xmlns="http://service.mycompany.org/">
<node1>
<node2 xmlns="">
<node3>hello World</node3>
</node2>
</node1>
</root>


When I generate a SOAP-message with WebServiceTemplate the
empty xmlns="" at node2 is suppressed.

e.g.
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/><SOAP-ENV:Body>
<root xmlns="http://service.mycompany.org/">
<node1>
<node2>
<node3>hello World</node3>
</node2>
</node1>
</root>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Can anybody give me a hint what to do to get the empty xmlns in
the SOAP-message?

Thanks Olaf

below is my testcase

import java.io.ByteArrayOutputStream;
import java.io.StringReader;
import java.io.StringWriter;
import java.io.IOException;

import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;

import org.springframework.ws.client.core.WebServiceTempl ate;
import org.springframework.ws.client.core.WebServiceMessa geCallback;
import org.springframework.ws.WebServiceMessage;
import org.springframework.ws.soap.SoapMessage;


public class Test {

/**
* @param args
*/
public static void main(String[] args) {
String message =
"<root xmlns=\"http://service.mycompany.org/\">\n"+
"<node1>\n"+
"<node2 xmlns=\"\">\n"+
"<node3>hello World</node3>\n"+
"</node2>\n"+
"</node1>\n"+
"</root>";

StreamSource source = new StreamSource(new StringReader(message));

StringWriter strwout = new StringWriter();
StreamResult result = new StreamResult(strwout);
WebServiceTemplate webServiceTemplate = new WebServiceTemplate();

System.out.println("The original xml\n"+message);

webServiceTemplate.sendSourceAndReceiveToResult("h ttp://localhost:8080/myservice"
,source
,new WebServiceMessageCallback() {
public void doWithMessage(WebServiceMessage message) {
try {
ByteArrayOutputStream baout = new ByteArrayOutputStream();
((SoapMessage)message).writeTo(baout);
System.out.println("The SOAP-message\n"+new String(baout.toByteArray()));
} catch(IOException ex) {
ex.printStackTrace();
}
}
}
,result);
}
}

Spring-WS has very little influence on how the SOAP envelope is created. You could try:

<root xmlns:tns="http://service.mycompany.org/">
<tns:node1>
<node2>
<node3>hello World</node3>
</node2>
</tns:node1>
</tns:root>
