Hi,

A quick question about your working flow as I can't understand it.


How is the cxf client working with camel router?

same context as what
I am doing. What I'm trying to do is to create a Camel componentwhichamong other things invokes an external web service using CXF. UsingCXF
alone is not a problem, however, getting all of Servicemix
4/Camel/OSGi/Spring DM working together is not so easy. Perhapssomeone can
shed some light on what
I am missing, or point me to a working example of something similarto what
I am doing. I've looked
through both the Servicemix 4 and CXF examples, but none are closeenough to
what I am doing to be
of much help.

Let me start with the beans.xml file. It looks like the following:

So, one of the questions is, is the camel-spring-osgi bundle runningin
Servicemix?

Here's the output from osgi:list command:

ka...@root> list |grep -i camel
[  98] [Active     ] [            ] [       ] [   60] camel-core

[ 156] [Active     ] [            ] [       ] [   60] camel-jms

(2.2.0.fuse-01-00)
ka...@root>

So, it appears that the camel-spring-osgi bundle is present.
Perhaps I need to include additional Import-Package? But if so, do Ineed to
do this for
every namespace? As I mentioned earlier when I added the additionalimports
into my
beans.xml I get additional errors with reagards to finding
NamespaceHandlers.
I've been working on this for some time now, getting a bitfrustrated and
thinking why does it
need to be so difficult? If anyone has encountered this problem andcan
explain to me how to
correct it, it would be much appreciated. Failing that, if someonehas a
working example of a
CXF client/server working in Servicemix 4, that would be appreciatedas
well.

Thanks.
