[Resteasy-users] Enabling Jackson in RESTeasy

[Lars R. C. <lr...@am...>]

We have a fairly large JBoss-based system in which we use RESTeasy for
a number of our web services. Jackson just came onto our radar as a
much better alternative for the various JAXB JSON implementations, and
I would like to use it. However, two of the three descriptions of how
to enable Jackson with RESTeasy don't apply in our system: We don't
use Maven, so we can't just add something to our Maven config, and we
don't have an explicit application class that extends
javax.ws.rs.core.Application since we just use @Path annotations and
resteasy.jndi.resources specs to designate our web services. I have
tried the third approach, mentioned in
<URL:http://wiki.fasterxml.com/JacksonFAQ?highlight=(\bCategoryJackson\b)>,
of making files in META-INF/services/javax.ws.rs.ext.MessageBodyReader
and -Writer, but that has no visible effect, I still end up with
Jettison-generated JSON. I cannot remove the superfluous JAXB/Jettison
jar files, as JBoss depends on them. I have successfully used Jackson
in unit tests that don't touch upon RESTeasy, and really like it, so
how should I add it when we don't use Maven or Application?

Thanks in advance,
