Jean-Christophe Durand commented on WSFC-286:
---------------------------------------------

Well, this is what I actually mean.
The WSF/PHP client sends a CreateSequence request behind anonymous address and offers \
a sequence identifier. This should not be accepted, according to the specificatioo(I \
might be missing something or mis-understanding the specification). Here is the \
createsequence XML I get when my WSF client initiates the conversation

> Key: WSFC-286
> URL: https://wso2.org/jira/browse/WSFC-286
> Project: WSO2 WSF/C
> Issue Type: Bug
> Components: Apache Axis2/C
> Affects Versions: 1.1.0
> Environment: All environments. WS-RX v1.1
> Reporter: Jean-Christophe Durand
> Attachments: patch.c

> 
> Hi,
> I have been trying to get WS-RX 1.1 working between my Php client (e.g WSF/Php) and \
> my JBoss server (JBossWS module). It took me a couple of days (I am neither a C nor \
>                 an Axis2 expert) to find out it cannot work for the following \
>                 reason:
> - the endpoint contains the "http://www.w3.org/2005/08/addressing/anonymous" \
> address and is also offering a sequenceId (<wsrm:Offer>urn:......</wsrm:Offer>) I \
> checked both WSF/C and JBossWS implementations and I found the following comment in \
> JBossWS (which is copied from \
> http://docs.oasis-open.org/ws-rx/wsrm/200702/wsrm-1.1-spec-os-01-e1.html): the \
> offer of an Endpoint containing the \
> "http://www.w3.org/2005/08/addressing/anonymous" IRI as its address is problematic \
> due to the inability of a source to connect to this address and retry \
> unacknowledged messages (as described in section 2.3). Note that this specification \
> does not define any mechanisms for providing this assurance. In the absence of an \
> extension that addresses this issue, an RM Destination MUST NOT accept (via the \
> /wsrm:CreateSequenceResponse/wsrm:Accept element described below) an offer that \
> contains the "http://www.w3.org/2005/08/addressing/anonymous" IRI as its address. \
> So after reading the oasis specification, I have the feeling that both WSF and \
>                 JBossWS should be slightly modified to make sure that:
> - the php client does not send an offer when behind an anonymous address (making \
>                 sure it also works with strict implementation on the server side)
> - the server does not reject a request and rather disregard the offered sequence (I \
>                 am also reporting this to JBossWS)
> PS: attached to this document is the patch I wrote for to wsf_client.c file. It \
> might not be the best way of doing this but at least it worked for me ;-)
