This actually depends on how you are invoking the web service, if you are creating a axis stub and invoking the web service then, you can do something like this, But please note this works only after the call happens else returns null

In you xxxxxSoapBindingStub class in the particular method where u wanna capture req/res xml just add the following lines after the invoke() call.

Here is a sample from my helloService which takes a name.


 java.lang.Object _resp = _call.invoke(new java.lang.Object[] {name});

	 System.out.println(_call.getMessageContext().getRequestMessage().getSOAPPartAsString());

 System.out.println(_call.getResponseMessage().getSOAPPartAsString());

Hi,
  Thanks , but method call is going through the AxisServlet's doPost methood and through rpc to the webservice method.I am not using stubs .I tried to redirect to a custom servlet class which extends AxisServlet and could get hold of the request object.I need to pass one of the arguments in the request header to my webservice method.I had read about using MessageContext's SOAPMessage header  object to pass parameters , but not sure Can you help with this regard

>>.I need to pass one of the arguments in the request header to my webservice method
 can you clarify this?
 All I want to know is weather you want to add SOAP Header? or HTTP Header?
I am also wondering why is that you are extending a axis servlet?

First can you please tell are you coding for webservice implementation or the webservice client implementation?

i am calling a webservice method say testmethod(x,y,z).When the Axis Servlet intercepts this method call from the webservice caller,the request object has a value in its header say m=n which I have to access inside my webservice method testmethod..When i print the incoming request inputstream(whose code i have attached below), i get the following

<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:c2o="http://optinuity.com/c2o" xmlns:wsa="http://schemas.xmlsoap.org/ws/2003/03/addressing" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><SOAP-ENV:Header><wsa:mID>9a7ca1dc-5879-4c2f-927c-c67f8b462cb5</wsa:mID><wsa:ReplyTo>http://testbox:8080/itpam/soap</wsa:ReplyTo><wsa:Action>testMethod</wsa:Action><wsa:ReferenceParameters><c2o:ReplyMethod>AsyncSoapResponse</c2o:ReplyMethod></wsa:ReferenceParameters></SOAP-ENV:Header><SOAP-ENV:Body><testMethod xmlns="urn:usmRequestService">
<sessionID/>
<x>10001</x>
<y>1</y>
<z>10102</z>
</testMethod></SOAP-ENV:Body></SOAP-ENV:Envelope>

I need to access the mID value inside the testmethod webservicecall.That's the reason I extending the Axis Servlet to get hold of the request header info.
public void doPost(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response){

    try{

      

      

      

     System.out.println(request.getHeaderNames());

  // Traverse the HTTP headers and show them on the screen

     for(Enumeration enumr = request.getHeaderNames(); enumr.hasMoreElements(); ) {

     String header = (String)enumr.nextElement();

     String value = request.getHeader(header);

     System.out.println(" "+header+" = "+value);

     }

  

     super.doPost(request,response);

    }

    catch(Exception e){

      

      e.printStackTrace();

    }

    }

According me this only give access to HTTP Header and not the SOap Header,

Can you show me the code where you are actrually making the request to the web service.

if you ask ideally you need to do something like this, create a soap client (stub) using axis and then invoke the methods of this stub (operations) via your servlet and then u can use my previous apporach, else u can try a direct client call some thing like this  http://www.experts-exchange.com/Q_23396120.html

Hi all,
  Thanks for the comments.The webservice call is made by a 3rd party component.According to my previous comment, the request inputstream does contain the soap envelope information.However, i was able to get this working , by adding the following code in my webservice method.
 MessageContext mc = MessageContext.getCurrentContext();
        MimeHeaders mh=mc.getRequestMessage().getMimeHeaders();
        String[] mhStr = mh.getHeader("mID");
        log.info("Message ID"+mhStr[0]);

This is working fine.Is there any problem with this approach

I am actually wondering how is that code working because as per the documentation( as well as the naming style) it says

"getMimeHeaders():
          Returns all the transport-specific MIME headers for this SOAPMessage object in a transport-independent fashion."

check:
http://ws.apache.org/axis/java/apiDocs/javax/xml/soap/SOAPMessage.html

So ideally it must give u only HTTP header and not soap header, as your Mid is coming as part of the soap header it must have been something like this
MessageContext mc = MessageContext.getCurrentContext();

        Message message=mc.getRequestMessage();
 

SOAPPart sp = message.getSOAPPart();

 SOAPEnvelope se = sp.getEnvelope();

 SOAPHeader sh = se.getHeader();

Iterator litr = sh.examineAllHeaderElements();
 

while(litr.hasNext()) {
 

     SOAPHeaderElement  element = ( SOAPHeaderElement )litr.next(); 

  //print the element actually element.getChildElements(); should give u the actual headers.

}
