Thanks for the response Paul.
What we are doing, may be thought of as using the ContextResolver
outside the context of Jersey resource method calls. For example, I can
configure a ContextResolver as a spring bean, and then look up and use
that spring bean elsewhere.
This is a handy way to use a single approach (JAXB configs) to manage
conversion of POJO to JSON string. Some of these conversions are handled
by Jersey, some are manually invoked in application logic.
Jersey does this automatically for resource method signature types, and
Collections of JAXB classes work in that case. What I'm not sure how to
do, is make the ContextResolver work this way for Collections of JAXB
types that are NOT automatically handled by Jersey (since these
Collections of JAXB types are being used outside of any Jersey resource
methods). It works fine to use ContextResolver in this way for
non-Collections.
Another way to think of this situation is that we are trying to use some
of the Jersey infrastructure as a generic (read: used in cases outside
of Jersey resource method calls) way to generate JSON format strings
based on JAXB configuration.
Thanks!
Tyson

Hi Tyson.
Collections of JAXB classes are supported.
See the JAXB sample for XML:
http://download.java.net/maven/2/com/sun/jersey/samples/jaxb/1.0/jaxb-1.
0-project.zip
Although this is for XML it should also work for JSON.

Hi -
We have some JSON format services created, which are all working well,
based on the json-from-jaxb example.
Is there anyway to get the JSON format string of a Collection<?> type
using the ContextResolver injected via @Context? We can do it with JAXB
types, but I'm trying to figure out if we can avoid wrapping the
collections.
Background:
We have some occasions where we need to "manually" generate JSON format
strings and use a String type result on a resource method, which works
fine when we modify the types in our JAXBContextResolver class.
We would like to be able to also "manually" generate JSON format strings
from Collection<?> types, but I'm not sure if this is possible?
The method:
JAXBContext getContext(Class<?> objectType)
Only receives type info for the collection instance, not the type of its
contents.
Any ideas on a way around this?
Our alternative will be to not rely on JAXB config to generate JSON
format in these cases, which is less than ideal.
Our use case for doing this is that we have some JSP templates that
serve HTML + javascript, and the javascript uses some AJAX style widgets
that consume JSON data. In some cases, it is best for us to serve all
the content at one time, where the JSON data is embedded into the HTML
as a static string in JSON format.
Thanks for any ideas!
