Hi,
I'm currently attempting to deploy a "Subscribe" service unit to a
servicemix-wsn2005 component (SM version: 3.1-incubating).
I generate the SU with Maven tooling and then create "... one ... (file)
with an xml extension, ... containing a single WS-Notification request.
The currently supported set of requests include:
* Subscribe"
(see
http://incubator.apache.org/servicemix/servicemix-wsn2005.html#servicemi
x-wsn2005-CreatePullPoint)
However, when I deploy the SU, I get an error*), telling me that
servicemix-wsn2005 does not accept deployments. I also provide the
contents of my xml-file**) and my servicemix.xml component
configuration***). Please note that the same subscription - done via
static, servicemix.xml configuration - is working fine.
Any ideas of what is going wrong? Does the naming of the XML file
containing the Subscribe request matter?
Thanks in advance,
Ciao, Philipp
