java - What are JAX-WS Interceptors (also known as handlers)?

Question

What are JAX WS Interceptors? Where do I find info regarding the same!

Answer 1

JAX-WS interceptors (also called handlers) are used to weave in aspects of the request in a transparent way. Example of this are logging or requests/responses, adding security headers to the message, encryption, compression, etc. A single interceptor can manipulate either the logical payload (content) of the message or the protocol of the message, but cannot do both.

See here for the introductory documentation on them.
