Processing Instruction

["Thallapragada, Sowmi" <So...@telenav.com>]

How can I add a processing instruction in my response XML? We would like to add something like:

<?access-control allow="*myvalue"?>

before the SOAP envelope. Any help is appreciated.

RE: Processing Instruction

["Thallapragada, Sowmi" <So...@telenav.com>]

The idea is to expose our service both as a SOAP service as well as a REST service, which I believe is what Axis2 is built to do.

However, one of our clients has a hard requirement of the response having a processing instruction in the XML document when exposed as a REST service. Something like:

<?xml version="1.0"?>
<?my-pi allow="abc"?>
<responseBody>
..
</responseBody>

We were intending to do this by manipulating the envelope object available through the MessageContext in either a module handler or a message formatter. But looks like that is not possible. 

So should we just write a custom formatter which would write whatever message we need directly to the available OutputStream? Is this the best approach or is there something that can be done via configurations (best would be services.xml)

Thanks for your responses.

If you are using Axis2, then I assume that you cannot choose the web
services implementation, you ARE using SOAP not REST.
REST does not ignore the SOAP header or Envelope; there is no such
thing when you are using REST services. You may return plain text, or
some custom XML or some JSON structure, or some 'standard' XML like
Atom.

What is the processing instruction for? Where in the message is your
server expecting it to be?

Thanks Jorge.

So if we have access to an "Envelope" (via a custom Message Formatter or a Module Handler), would it suffice to add the PI to the SOAP Body since Envelope & SOAP Header are ignored in REST? Or would it have to be added to the parent of the "Envelope" (which I am not sure how to access as it is NULL in whatever tests I am performing)?

Thanks Andreas. 

Does this hold true for REST style services as well?
