CXF interceptor chain, servlet filter chain, JAX-RS filters

[Charlie Read <ch...@beebell.com>]

I have noticed three separate mechanisms for intervening
in the request / response processing:

  - CXF interceptors
  - JAX-RS filters
  - servlet filters

Can someone explain the processing priority of each of these chains
with respect to one another?

For example, is the priority servlet filters => CXF interceptor => JAX-RS
filter,
or something else?

Thanks!
Charlie

Servlet filters go first.
Next, if you prefer doing JAX-RS 2.0 only, we have
PreMatch Container Request Filter, then per-method specific Container 
Request Filters,

If you'd like to use native CXF interceptors instead of filters, then we 
have

Servlet filters -> CXF interceptors.

If you mix JAX-RS 2.0 filters & CXF interceptors, then

Servlet filters -> CXF interceptors before UNMARSHAL phase ->
PreMatch Container Request Filter -> CXF interceptors after UNMARSHAL 
phase -> per-method specific Container Request Filters
