How to enable Jackson JAX-RS provider or tell which provider is being used?

Hi all,

I am new to the wonderful world of JBoss and I'm trying to write a simple JAX-RS application. After numerous searches and frustrating attempts at trying to figure this out, I'm hoping that someone can give me an answer on this forum.

In general my application is working (I can make a web service call to my app, and it retrieves the required info from the DB and returns JSON back). The only problem I have is that it's not correctly encoding my String backed enum fields. I should mention that my value classes and enums are annotated with JAXB annotations (so I can also produce XML output). In hopes of fixing this, I annotated my enum with @IgnoreMediaTypes("application/json") and @JsonSerialize(), giving it an enum serializer class that I implemented. This didn't make a difference.

So my question is - do I need to do anything special to make sure that Jackson provider is being used for my JSON serialization/deserialization? How can I tell which provider is being picked by the system? I'm using JBoss 7.0.2 Final.

Thanks.

I was able to solve my problem with the @Json* annotations not being recognized by modifying my manifest file as described here: http://jira.codehaus.org/browse/JACKSON-641
It appears that RESTEasy 2.2.1.GA, which is included in JBoss 7.0.2 has a problem with its Jackson integration and is not initalizing something properly. Adding Jackson dependencies to the manifest seems to fix the problem.
