Hi Michal
Could you please provide a small complete sample? I have changed the
route as described in your email, but it works (I had to install the
camel-jetty) feature. You have implemented the class WsDelegate but you
have not written where do you use it - probably somewhere in the process
definition.
The stack trace says
Caused by: java.lang.ClassNotFoundException:
javax.xml.namespace.QNameat
In my opinion your bundle is missing the import of this package. If you look in
one of the jaxws samples (e.g. cxf-osg), import of the package
javax.xml.namespace is added to the maven bundle plugin configuration.
<Import-Package>
javax.jws,
javax.wsdl,
*javax.xml.namespace,*
org.springframework.beans.factory.config,
*
</Import-Package>
I think, you should add this (and perhaps some additional) packages into the
import definition
Best regards
