Re: Definining interceptors in camel-cxf

S. Ali Tokmen Wed, 21 Jan 2009 00:02:48 -0800

Hello

I also have this impression :) I've tried with a simpler, CXF-onlyexample, and it still does the exact same exception!


The only thing I do it to add the following in the beans.xml file:

   <!-- !!! Enabling this results in a NPE !!! -->
   <cxf:bus>
     <cxf:outInterceptors>
       <ref bean="LoggingOutInterceptor"/>
     </cxf:outInterceptors>
   </cxf:bus -->

I'm pretty sure I'm forgetting something, just cannot see what.

All source codes are available on the following SVNs:

   svn://svn.forge.objectweb.org/svnroot/jonas/sandbox/wss-propagation-parent
   revision 16259 for the CXF-only version
   svn://svn.forge.objectweb.org/svnroot/jonas/sandbox/camel-jonas4
   revision 16258 for CXF + CAMEL

Versions used are CAMEL 1.5.0 and CXF 2.1.3.

Cheers

Hi,

Can you send me your test case, and which version of camel are you using?
It's looks like a cxfEndpoint configuration issue.

Anyone has any idea? I'll start debugging CXF shortly, now waiting for
package downloads.

Please try the last verion of Camel 1.5.1-snapshot or Camel 2.0-snapshot.
I just fixed some bus related issue in camel-cxf component.

Hello, Willem

The cxf:bus approach would be exactly what I need, but when I enable it
I have the impression Camel-CXF ignores all of it. Did you try out
anything similar?

Hi

You can set the interceptors into cxf bus[1], then all the CXF
endpoints
create by CAMEL will use them.

Hello, Pawel

Thank you for this quick response. I now have another issue: I would
actually be interested in defining these properties globally, i.e. for
all CXF endpoints created by CAMEL. This way, people programming the
routes would only use CXF URLs and not create the CXF beans by hand.

Thank you

Hello

In CXF, one can define a serioes of interceptors, inbound and
outbound, for
doing many actions. Our implementation defines some Processor
interceptors
for handling security-related tasks (namely, serializing and
deserializing
Security Contexts).

In CXF-Spring, this is done using the jaxws:inInterceptors tag in
the
jaxws:endpoint definition.

Now, I would like to integrate this mechanism into CAMEL... And the
question
is: how can we define CXF interceptors in CAMEL? Programmatic
definition
works perfectly for me -if CAMEL for example defines a default CXF
bus for
itself, getting a reference to it and adding my interceptors for all
camel-cxf endpoints would be great.

Thanks
