Remove headers from OSB Proxy WS

Their are many times when we notice that when we call any ws from OSB web service, we find UN-necessary information in proxy WS header response.

As this header data is available in time of WS response, so does not bind the end client to send those headers in the WS request, But here question is how we can manage these headers to end user will not receives these headers in his final response of OSB proxy WS.

As in OSB their are many context variables available, which can help us to remove these headers from the proxy WS response.

Predefined Context Variables:

header
body
attachments
inbound
outbound
etc...

by using the header context variable we can remove those extra headers from WS response.

Example Scenario: In this example scenario, we are calling a simple BPEL WS using BPEL DIRECT-BINDING with OSB Business soa-direct.

1.Create a business service

2.Create a proxy service, which will call this BPEL WS.

3.Let us test this WS.

As you see in the attached test result, we are getting

<Header>
      <wsa:ReplyTo xmlns:wsa="http://www.w3.org/2005/08/addressing">
         <wsa:Address>http://www.w3.org/2005/08/addressing/anonymous</wsa:Address>
         <wsa:ReferenceParameters>
            <instra:tracking.ecid xmlns:instra="http://xmlns.oracle.com/sca/tracking/1.0">4d7f5aac5fbbb28b:653f1acf:14d7a6669ef:-8000-000000000000005f</instra:tracking.ecid>
         </wsa:ReferenceParameters>
      </wsa:ReplyTo>
   </Header>

this information is generated from OSB proxy layer, which is not required for end client, here ques is how we will remove this headers,

Here OSB tricks come and we will change the proxy WS layer.
