Module Development, Add Header Segment

[Former Member]

Hi Guys

I want to write a module where in I could be able to add the header segment to the XML Header.

I am not sure abt the methods to be used, is there any documentation giving details abt the methods which could be used.

Hi Dheeraj,

Can you please elaborate your requirement?

My understanding from ur post is you are trying to insert a header segment in an XML payload which doesnot have any header segment.

Input before conversion Module:

XML

-

---

Item1

data

Item2

data

...

Input After conversion Module:

XML

-

---

Header segment

Hdr data

Item1

data

Item2

data

...

Is this correct?

Hi

This is a sample soap message which i am trying to get, if you see in this, there are segment in the soap header part, which in normal way i cannot achieve in XI, so was just wondering if there is any method available in adapter module development where in i could do that.....

<b> <soapenv:Header> 
  <ns1:SessionHeader soapenv:mustUnderstand="0" 
xmlns:ns1="urn:enterprise.soap.sforce.com"> 
   <ns1:sessionId>6l9auFNpYPGRiIh9St82kkGBlUtIlWMt0_jXlNKOSU</ns1:sessionId>
  </ns1:SessionHeader>  </soapenv:Header> </b>
 <soapenv:Body> 
  <convertLead xmlns="urn:enterprise.soap.sforce.com"> 
   <leadConverts> 
    <accountId>001300000019ykD</accountId> 
    <ownerId xsi:nil="true"/> 
    <sendNotificationEmail>true</sendNotificationEmail> 
   </leadConverts> 
  </convertLead> 
 </soapenv:Body> 
</soapenv:Envelope>

Hi Dheeraj,

Modify the following code and add your Header segments and deploy it as an EAR Archive.Note Implement your <b><i>YourClass </i></b> code in such a way that it should add Header segments in between your existing SOAP Message.

You can access the incoming message using

payloadData.getInputStream()

and after processing your message set your newly created message using

payloadData.setContent(outXML.toByteArray())

Hi Dheeraj -

The SAP help site points you to where the JavaDocs for Adapter and Module development can be found:

http://help.sap.com/saphelp_nw04/helpdata/en/87/3ef4403ae3db12e10000000a155106/content.htm

You can also get it by downloading the latest Adapter Framework SP from Service MarketPlace (e.g. SAPXIAF15_0-20000273.sca). You can get that here:

https://smpdl.sap-ag.de/~swdc/012002523100000248062005D/SAPXIAF15_0-20000273.sca?_ACTION=DL_DIRECT

From this you would have to extract 'sample_ra.sda' and then within that 'sample_ra.rar' and then within that you'll find 'sample_ra.jar'. Once you extract the jar, open 'index.html'.

I did a quick scan of the <i>Message</i> interface and didn't really see a method to set a custom header. But maybe I missed something.
