Thx a lot Colm,
actually i think my problem was that I totally do not understand what does
WSS4JInInterceptor do or is supposed to do?
Javadoc for the method handleMessage says only this:
Description copied from interface: Interceptor
Intercepts a message. Interceptors need NOT invoke handleMessage or
handleFault on the next interceptor - the interceptor chain will take care
of this.
which is quite useless ;-(
After seeing examples in CXF User guide i assumed that it was kind of
preparatory interceptor - one that will prepare context for further
processing - hence the need to configure it with the
PasswordCallbackHandler, but it seems it is not so?
It would be nice if someone clarified the functionality of this interceptor
and what are all of his configuration options. Informatio on
http://cwiki.apache.org/CXF20DOC/ws-security.html is very basic and lacking
any explanations....
thx
