Changing the value of the SOAPElement in the SOAP message

Question

Now another problem I encountered was of overwriting a value in the SOAP message by my value. SOAPElement interface which extends Node interface provides me the method getValue() to get the value of the node but doesnt give me any method to set any other value instead of this.
<token xsi:type="xsd:string">token123</token>
I want to replace the value "token123" with my value.
Is there no provision for altering a value in the SOAP message? Is this due to security contraints?
If yes then can we detach the same node and add a similar node with the new value. I wanted to try the same using addChildElements() method but then the problem here is how do I create a new SOAPElement in the handler as its an interface and not a class. Why I want to add a similar node is because I am having the definition of this object in the WSDL file, so if I attach the node corresponding to the parameter of the object then I would get the object populated with this value at J2EE or .net layer.
Also I thought of adding an attribute to the same node but then since this attribute will not be defined in the WSDL, the value of this attribute will not populate the java object at the J2EE layer. Hence attribute introduction also didnt help.
This is the userData object in the soap body:
</q1:FetchDetailsInput><q2:UserData xmlns:q2="java:com.anthem.enb.common.data" xsi:type="q2:UserData" id="id2">
<password xsi:type="xsd:string">12345</password>
<token xsi:type="xsd:string">token123</token>
<userID xsi:type="xsd:string">vikas123</userID>
</q2:UserData>
This is my code to extract the values from the above message:
Iterator i = ctx.getMessage().getSOAPPart().getEnvelope().getBody().getChildElements();
System.out.println(" i.hasNext() =" + i.hasNext());
while (i.hasNext())
Object obj = i.next();
System.out.println(" obj :" + obj.getClass());
if (obj instanceof SOAPElement)
SOAPElement e = (SOAPElement) obj;
System.out.println("e :" + e);
String operationName = e.getElementName().getLocalName();
LOG.info(CLASS_NAME + "operationName :" + operationName);
if (operationName.equals("UserData"))
Iterator j = e.getChildElements();
LOG.info(CLASS_NAME + " j.hasNext() : " + j.hasNext());
while (j.hasNext())
Object obj2 = j.next();
LOG.info(CLASS_NAME + " obj2 :" + obj2);
LOG.info(CLASS_NAME + " obj2 :" + obj2.getClass());
if (obj2 instanceof SOAPElement)
SOAPElement eGrandChild = (SOAPElement) obj2;
String operationName2 =
eGrandChild.getElementName().getLocalName();
if (operationName2.equals("userID"))
String strPass = eGrandChild.getValue();
LOG.info(CLASS_NAME + " strPass:" + strPass);
else if (operationName2.equals("password"))
String strUserID = eGrandChild.getValue();
LOG.info(CLASS_NAME + " strUserID:" + strUserID);
else if (operationName2.equals("token"))
String strToken = eGrandChild.getValue();
Please help.

how do I create a new SOAPElement in the handler as its an interface and not a class?Here is an example:
<example>
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage m = messageFactory.createMessage();
SOAPEnvelope env = m.getSOAPPart().getEnvelope();
SOAPBody body = env.getBody();
SOAPElement fResponse =
body.addBodyElement(env.createName("fResponse"));
fResponse.addAttribute(env.createName("encodingStyle"),
"http://schemas.xmlsoap.org/soap/encoding/");
SOAPElement result =
fResponse.addChildElement(env.createName("result"));
result.addTextNode("test");
ctx.setMessage(m);
</example>
