Hi Juan Carlos, I've just done a test with Jackson on Java SE and it automatically serializes the beans to JSON based on the Accept header.
Are you sure you deployed the following JARs to GAE? - org.restlet.ext.jackson.jar - org.codehaus.jackson.core.jar - org.codehaus.jackson.mapper.jar Maybe there is a specific issue on GAE only, but that would be strange. Did you test on Java SE/Java EE to see if the behavior is different?

Hi, I'm implementing a RESTFul webservice in GAE. I've tried with Restlet 2.0 M6 and XStream, but got several problems. I've upgraded to Restlet 2.0 M7 and used Jackson extension. My question is related to automatic content handling, as when using XStream extension I was getting the proper xml/json depending on the Accept header provided. However this is not working with Jackson and i'm getting the following warning: Unable to find a converter for this object : es.pentasoft.racing.cloud.r...@147e0ba Thanks in advance, ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=24437 77 ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2450046
