Got it working. You need all the fasterxml jar files, and you'll need the org.codehaus.woodstox jar files used by fasterxml. In my case that gets me the xml and json encoding of jaxb annotated files that I was looking for.
Here is the list of working jar files for the benefit of anyone who may come across this: org.restlet.ext.jackson.jar org.restlet.ext.servlet.jar org.restlet.jar com.fasterxml.jackson.annotations.jar com.fasterxml.jackson.core.jar com.fasterxml.jackson.csv.jar com.fasterxml.jackson.databind.jar com.fasterxml.jackson.jaxb.jar com.fasterxml.jackson.smile.jar com.fasterxml.jackson.xml.jar com.fasterxml.jackson.yaml.jar org.codehaus.woodstox.core.jar org.codehaus.woodstox.stax2api.jar Again, these get you encoding of jaxb annotated classes to xml and json. This is a much longer list of jar files then was necessary for restlet 2.1. The entire set of fasterxml jar files are required or else you'll get class not found exceptions when it tries to load converters for all the formats it supports. I'd like to figure out, or see supported, a way to avoid the need to load only specific fasterxml converters. e.g. I don't care about csv, smile, and yaml and would prefer not to load them. ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=3050436
