Unable to change UAP soap in envelope using java SoapMessage

Question

I am trying to create a simple SOAP message to send from a client, but I (apparently) cannot change the namespace URI of the "soap" in the envelope.

This is what the soap header should look like:

<soap:Envelope xmlns:soap="http://www.w3.org/2001/12/soap-envelope/" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding/"> ... </soap:Envelope> 

So, I have the following code:

  final SOAPMessage sm = MessageFactory.newInstance().createMessage(); final SOAPPart sp = sm.getSOAPPart(); final SOAPEnvelope se = sp.getEnvelope(); final SOAPHeader sh = se.getHeader(); final SOAPBody sb = se.getBody(); se.removeNamespaceDeclaration(se.getPrefix()); se.addNamespaceDeclaration("soap", "http://www.w3.org/2001/12/soap-envelope"); se.setPrefix("soap"); sb.setPrefix("soap"); sh.setPrefix("soap"); se.setEncodingStyle("http://www.w3.org/2001/12/soap-encoding/"); 

However, when I print a message before sending, the following is my envelope:

 <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding/"> 

Note the differences in the xmlns: soap URI in the "must be" section and the actual one.

If I change the first argument of calling addNamespaceDeclaration to soap instead of soap, this is the next envelope I get:

 <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soapy="http://www.w3.org/2001/12/soap-envelope" soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding/"> 

I assume this may be due to the fact that the addNamespaceDeclaration call is not something like changeNamespaceDeclaration , and it is ignored, given that the namespace is already present, but I cannot find something that works (I already tried setAttributeNS ).

EDIT: I just realized that setAttributeNS stupid because it is a namespace change, not a URI. EDIT AGAIN: I'm a little confused as I keep searching, sometimes I see that the naming goes soap:"Namespace" , so in that sense I want to change the namespace ... but I thought the namespace is a "soap", part. Any clarifications?

This is my first post, so I apologize if I ask for something that has already been solved, but I searched for it, and most of what I found is related to changing the namespace (for example, from SOAP-ENV, which is the default namespace for soap), not the URI itself. Thanks in advance.

In general, you do not need to manually change the SOAP namespace. You probably want to create a SOAP 1.2 message (which has a different namespace than SOAP 1.1). Try to remove all lines that change the namespace from your code and change the first line to

 final SOAPMessage sm = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(); 

If you really need to specify which prefix should be used, this code works:

 SOAPMessage sm = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage(); sm.getSOAPPart().getEnvelope().setPrefix("soap"); sm.getSOAPPart().getEnvelope().removeNamespaceDeclaration("env"); sm.getSOAPHeader().setPrefix("soap"); sm.getSOAPBody().setPrefix("soap");
