Hello,
Having started trying to get more understanding on Servicemix,
I've made a simple test-assembly for the smx http component.
It's setup is quite simple: poll for a file using the smx file
component. Its content will then be sent from via smx http
provider to an in-only smx http consumer, and finally written
back to file.
When I deploy the assembly, all seems to be in order. Yet when
the process is activated by placing a file in the poll location,
an exception is thrown on the http component:
java.lang.Exception: Invalid status response: 302
(The complete trace will be added after the question.)
Status response 302 indicates a redirect in the consumer url,
which strikes me as an odd result for a direct smx to smx http
transaction.
In further testing, I found the result differs when I rewrite
the units to an in-out MEP. This time, the exception turns out
to be:
error: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in
prolog at [row,col {unknown-source}]: [1,0]
The message that's being sent is an normal xml message, so I
don't think this is the issue.
At the moment, I'm grasping at straws; If this is a MEP problem,
it seems it would require a robust-in-out, of which I'm not sure
how to create it. (Maybe a drools router?) And if it's not a MEP
problem, I'm flat out of ideas at the moment.
If anyone could give me a pointer in the right direction, that
would be great. In short, the question would be:
How do I get this silly little thing to work?
I'll add snippets of the file and http SU xbeans, containing
the relevant configuration information. The in-out version has
been made by adjusting the MEP value in the http consumer and
abusing a EIP pipeline to force the file output into an in-out
exchange.
Kind regards,
Rob.
