Soap Headers
Hi,
I'm currently implementing a process which uses the incoming soap
headers as the soap headers for the invocation of a webservice.
Simply put:
Client --> Process --> Webservice
So the client provides some headers to the process, which are being
used as the headers for the invocation of another webservice.
However since custom headers may be transferred as well (which are not
known in advance), I can't use the standard dynamic headers, or can I?
Luckily some ODE extensions seem to exist (http://ode.apache.org/assign.html):
urn:ode.apache.org/axis2-il/headers/
name: in
name: out
<bpel:assign>
<bpel:copy>
<bpel:from variable="input" part="payload"
extension="urn:ode.apache.org/axis2-il/headers/:in"/>
<bpel:to variable="output" part="payload"
extension="urn:ode.apache.org/axis2-il/headers/:out"/>
</bpel:copy>
</bpel:assign>
However this doesn't seem to work either. I always keep getting an error.
Without providing a part or header attribute, the file won't even
compile, therefore I assume that any input may be valid (part payload
exists btw)?
Invoking gives me the following error:

Re: Soap Headers
Posted by Markus Piff <ma...@gmail.com>.
Hi Milinda,
thank you for your answer and your kind offer. Using an ESB could help
me solve the problem although it's not very elegant.
Luckily one can do it also in another way. I finally succeeded to read
and set soap headers without any knowledge in advance with the help of
XPath.
If anyone encounters the same problem, the following snippet does the
job (first read the incoming headers, then set those in the outgoing
message):
<bpel:forEach counterName="counter" parallel="no">
<bpel:startCounterValue>"1"</bpel:startCounterValue>
<bpel:finalCounterValue>count($input.payload/../../*[@headerPart="true"])</bpel:finalCounterValue>
<bpel:scope>
<bpel:sequence>
<bpel:assign>
<bpel:copy ignoreMissingFromData="yes">
<bpel:from queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0"
expressionLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath2.0">
ode:insert-as-first-into($output.payload/../..,
$input/*[@headerPart="true"][$counter])
</bpel:from>
<bpel:to>$output.payload/../..</bpel:to>
</bpel:copy>
</bpel:assign>
</bpel:sequence>
</bpel:scope>
</bpel:forEach>
Note however that this solution is bound to ODE interals, this may not
work with other BPEL engines!
Cheers,
Markus

Re: Soap Headers
Posted by Milinda Pathirage <mi...@gmail.com>.
I think you can copy all the incoming headers to the outgoing call and place
ESB(Apache Synapse or Alternative) in-between external service and BPEL
process to manipulate the headers. If this approach is good for you and you
want to know more information on this, please reply back to this thread.
Thanks

Re: Soap Headers
Posted by Markus Piff <ma...@gmail.com>.
Hi Łukasz,
thanks for your answer.
The article is about dynamic headers, which have the restriction to
know in advance which headers are present in the incoming message. In
your case you know that the ProcessId header is set. You can't simply
copy all header elements to a variable unless you know which are
present.
Unfortunately I need to access all soap headers without the knowledge
which are present. Hints, anyone?
Cheers,
Markus

Hi Markus,
Take a look at this:

Hope this solves your problem :)
cheers,

Re: Soap Headers
Posted by Markus Piff <ma...@gmail.com>.
Hi,
according to http://mail-archives.apache.org/mod_mbox/ode-commits/200803.mbox/%3C20080327234046.E67191A9832@eris.apache.org%3E
the extension urn:ode.apache.org/axis2-il/headers/ has been removed
two years ago. Has anybody any information on this?
All I need is get access to soap headers, read them and set them again
for another call (without knowing which headers are present).
Cheers,
Markus
