Jersey 2 Client - how to get JAXBContext - jaxb

Question

I can find Jersey 2 documentation on using custom JAXBContext but what I can't find is documentation on reusing its JAXBContext.
I want to be able to marshal/unmarshal entities without making an HTTP request (e.g. unmarshal some XML files on the classpath, marshal/unmarshal data for database I/O, etc.).
How can I get the JAXBContext instance that my Jersey 2 Client is already using?

Answer 1

I still haven't figured out how to get the JAXBContext but I have figured out how to reuse it:
client.target("file:///path/to/resource")
.register((ClientRequestFilter) requestContext ->
requestContext.abortWith(Response.ok()
.entity(new FileInputStream(Paths.get(requestContext.getUri())
.toFile()))
.build()))
.request()
.get(Planet.class);
Similar ClientRequestFilters can be used for returning strings or input streams from a database, etc. or for writing to a file-system or database.
