Retrieve or set a HTTP header from Oracle BPEL

With Oracle SOA Suite 11g patch 12928372  you can finally retrieve or set a HTTP header from BPEL. This patch comes with Patch Set 5 ( 11.1.1.6 )  and this patch can also be applied on PS3 ( 11.1.1.4 ), please download it from http://support.oracle.com

I made a simple test case with soapUI which adds an username and a message as HTTP header to the  service invocation.  In a second testcase I will mock this service in soapUI and BPEL will invoke this service and set an extra HTTP header property.

First step is to add a property to the binding.ws element of the service in the composite.xml. Add a property with name oracle.webservices.http.headers and as value the HTTP headers you want to use in BPEL
<property name="oracle.webservices.http.headers">username,message</property>


Next step is to define some BPEL variables for those HTTP Headers


In the receive activity of the BPEL process we can use fromProperty to copy the HTTP header property value to the BPEL variable. 

Do this in the BPEL source mode. 


Now you can use these variables in BPEL, I will use these vars in the return message.

Let's invoke the service from soapUI, we need to set the HTTP header properties with their values.



When we want to invoke a reference service and we also want to set some HTTP header properties.

We need also need to set the http.headers property on the binding.ws element on the reference in the composite.xml

<property name="oracle.webservices.http.headers">username,message,message2</property>


On the invoke of the reference service we need to use the toProperty and set the BPEL vars to these HTTP header properties.


When we test it again in soapUI we can see the invoke request of the soapUI mockservice, this contains the HTTP headers which we set in the BPEL process.

    Thanks for sharing this useful information. This would simplify handling http headers. I had a similar usecase in 11.1.1.3, tried several things in bpel, gave up and finally created a proxy service in OSB that can set http headers and let bpel call osb proxy service. Once we upgrade I will modify bpel to directly set http header. Thank you!!

    Given the features like httpbinding and http header manipualtion from bpel, Do you have an exmaple to invoke Rest based web service call directly from BPEL?

      Hi,

      this comes close, use the http adapter.

    Thanks for the pointer, it certainly helps in case of sending XML payload using REST but not for JSON. I know one of your old article talked about using JSON within OSB by adding JSON libraries to OSB server classpath. I was hoping to find an easy and efficient way to deal with REST/JSON directly from within BPEL.

    Edwin,

    We are using SOA 11g PS2.
    How can we achieve this in that.?

    We need to pass the following custom http headers.
    x_company_wss_username
    x_company_wss_password

    Thanks,

    Hi Edwin,

    I have installed SOA Suite 11.1.1.4 and weblogic server 10.1.3.4. I have deployed some composites on to the SOA Server where in i have used human tasks i.e. workflows inside the composites. I am trying to send a request from one of my webapplication but it is throwing me an exception which is described below.


    <ADF_FACES-60098:Faces lifecycle receives unhandled exceptions in phase RENDER_RESPONSE 6
    javax.faces.FacesException: javax.servlet.ServletException: OracleJSP error:
    javax.faces.FacesException: javax.el.PropertyNotFoundException: Target Unreachable, 'requestInfoView' returned null

    Can you please through a light if you have come acrossed it. As it is an urgent which needs to be resolved.

    Hi Edwin,

    We are using SOA 11.1.1.6.0; I tried the steps you have listed above to access the http header variable however BPEL could not read the header variable value.

    There was no error but header variable was blank; do we need to apply any patch separately?

    Is there a way to propagate http header (username/password) received from caller in composite/BPEL to the web service called by BPEL - as there was in 10g?

    Thanks,

      Hi,

      is the bpel wired to a service or is there a mediator before the bpel service component.
      it should work, but to do identity propagation you should use saml.

      try to set http headers and see if that works

      thanks

    Same problem. I'm trying to send a http redirect with a http binding setting status code 302 and Location http headers. Is that possible ?

    I'm using 11.1.1.6 and cannot read or write the http header.

    Can I use this on a http binding interface ?

    I'm setting http response headers on the reply.

    Hi Edwin,

    Can this be used to pass the 'Authorization' header as well?
    This would enable us to use this to pass values dynamically for Basic Authentication in BPEL (been looking for such a solution).

    Thanks,

      Yes Edwin, not only the patch was missing but the SOA 11.1.1.5 is not able to understand toProperties.
      I changed the toProperties to inputProperty and the Header information was being passed successfully.
      But, the issue is still not resolved as the service is returning 200 OK message and I am getting following error :
      javax.xml.ws.WebServiceException: javax.xml.soap.SOAPException: javax.xml.soap.SOAPException: Unable to read response: org.xml.sax.SAXParseException: Content is not allowed in prolog.

      Am I missing something or Is it that the HTTP Bindings adapter can't read the response header.

    Edwin- Thanks for this post. However I didnt get it working when Bpel is calling a Mediator.

    I set the Reference properties for Mediator + Invoke for Mediator in Bpel.
    But Bpel is not sending the Header to Mediator.

    If I test mediator separately it works fine , I am working on 11.1.1.17 and used the sample for mediator from : https://java.net/projects/oraclesoasuite11g/downloads/directory/Mediator

    Please suggest.

    was able to send the Header from Bpel to Mediator , But now the mediator is not able to fetch the Header value from header. Looks like Mediator always expects the header in format like :
    $in.header.inp1_UserNameHeader/inp1:UserNameHeader

    However when i send from Bpel , it is passed as below :


    SamInBpel





    Test




    Not sure what I am missing ?

    Hi Edwin,

    I have a HTTP Binding that does a post with a XML payload as an exposed service. I've been trying to set the mime:content-type of the input and output messages to application/xml but have been unsuccessful so far. Do you know where I set the content-type anywhere in BPEL?

    I've tried adding a tag in the WSDL file but that doesn't seem to work as well.

    Hi,
    We are unable to invoke a REST based service through BPEL using a HTTP Binding adapter. We are using jdev 11.1.1.6
    1. we are passing the following header to invoke a REST based service
    a) Authorization
    b) X-API-Key
    2. We have set the following properties in the composite.xml, under the reference tag of the service
    property name="oracle.webservices.http.headers" type="xs:string"
    many="false">Authorization,X-API-Key
    3. Also in the BPEL we are setting the header values in the Invoke




    4.The xsd for invoking the service is a complex xsd
    But we get the following error while invoking the service
    "unable to access the following endpoint(s): REPLACE_WITH_ACTUAL_URL"
    But we are able to get a response from the service through SOAPUI application

    Can you please suggest what can he going wrong here or what more needs to be done?

    Authorization

    Then, in BPEL I have create a new variable called Access_Token and add toProperties under the invoke section








    After I have set this in the BPEL i still get an error and fail to pass the custom HTTP headers. Below is the error.
