Hello,

I have a developed Rest service using RESTEasy framework and it works fine when I am returning XML response from my Rest controller. However I want to switch to JSON response and this is where I get the below error:

org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type: com.aviseurope.rm.ws.carsintegration.openpricingprogram.domain.OpenPricingProgramResponse of media type: application/json

In my application I initially had following jars:

• resteasy-spring-3.1.4.Final.jar
• resteasy-jaxrs-3.1.4.Final.jar
• resteasy-jaxb-provider-3.1.4.Final.jar

When switching to json format response I have now added below jar:

• resteasy-jackson-provider-3.1.4.Final.jar

Even after adding the resteasy-jacksom-provider jar. I continue to get the same error as mentioned above.

Am I missing anything here to get this to work to return JSON format response instead of XML? In my rest method I have kept below annotation:

@Get

@Produces(MeditaType.APPLICATION_JSON)

@Path("/countriesAndPPs")

public Response getCountryAndPricingProgram(@Context HttpServletRequest request)

{

...

}

Switching back to @Produces(MeditaType.APPLICATION_XML) works fine and I get the xml response as expected. My web application is hosted on JBOSS EAP 7.0.8.GA.

Appreciate any help to resolve the above issue. Thank you.
