Hi,

Can someone explain me what the difference is between SOAP header and Http Header. Can I use any of these two to do basic HTTP authentication. I'm using a Java Client for sending Webserce request.

When I opened a WSDL which my client sent me in soapUI, I this in the header of that SOAP. How do I set the header information?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:polh="http://ws.pol.com/PolContractService/2012-01-03/Polcontractservice_V1_0" xmlns:sec="http://ws.pol.com/IBC/2010-11-19/securitybasetype_V1" xmlns:mes="http://ws.pol.com/IBC/2010-11-19/messagecontextbasetype_V1" xmlns:man="http://ws.pol.com/PolContractService/2012-01-03/managecontractrequest_V1" xmlns:con="http://ws.pol.com/Common/2012-01-05/contractbasetype_V1">
   <soapenv:Header>
      <polh:headerContextParameters>
         <securityContextParameters>
            <sec:usernameToken>
               <sec:userName>?</sec:userName>
               <sec:password>?</sec:password>
            </sec:usernameToken>
         </securityContextParameters>
      </polh:headerContextParameters>
   </soapenv:Header>

Thanks

As per i know only diffrences is the body struture ...  you can use soap header is more secure

 

HTTP URL:

http://host:port/sap/xi/adapter_plain?service=BS_A&namepsace=http_test&interface=SI_A

 

SOAP URL:

http://host:port/XISOAPAdapter/MessageServlet?channel=party:service:channel

A SOAP header is tied to the SOAP message and can be used to transfer information specific to that request like authentication info etc. So basically it is that part of the data which might be required but is not part of the SOAP payload (request=>method, params etc).

However, it would go in as the body part of the HTTP POST request.

A HTTP header on the other hand will give some information about the HTTP protocol attributes like Content-Type, accepts etc. It is basically metadata to the server/client as to what attributes the HTTP transport protocol is using.

Thanks Anil,
 WHen I generated stubs, UsernameTokenType.java see code below.  How can I set those values in the header?
<soapenv:Header>
      <polh:headerContextParameters>
         <securityContextParameters>
            <sec:usernameToken>
               <sec:userName>?</sec:userName>
               <sec:password>?</sec:password>
            </sec:usernameToken>
         </securityContextParameters>
      </polh:headerContextParameters>
   </soapenv:Header>

UsernameTokenType userTokenType = new UsernameTokenType();
            userTokenType.setUserName("username");
            userTokenType.setPassword("password");
            SecurityBaseType  securityBaseType = new SecurityBaseType();
            securityBaseType.setUsernameToken(userTokenType);
            
            HeaderContextParameters headerContextParam = new HeaderContextParameters();
            headerContextParam.setSecurityContextParameters(securityBaseType);

I don't have the WSDL to help you out; but generally you can get the SOAP message from the message context and use its header part to put data

SOAPMessageContext messageContext //Got within the SOAPHandler
SOAPMessage msg = messageContext.getMessage();

SOAPEnvelope envelope = msg.getSOAPPart().getEnvelope();
SOAPHeader header = envelope.addHeader();
header.addElement(headerContextParam);
msg.saveChanges();
