Karaf - getting "Unable to load class" when installing feature

Question

I am new to cxf and camel and I am running into some issues when trying to use JacksonJsonProvider.

I am trying to define a cxf service endpoint which consumes a json object and sends the request to a camel route. The camel route is not important for my issue.

In my blueprint.xml file I have defined a bean for JacksonJsonProvider:

<bean id="jsonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/>

When I try to install my feature in karaf I receive the following error:

BlueprintContainerImpl | ?
? | 21 - org.apache.aries.blueprint.core - 1.4.2 | Unable to start blueprint container for bundle test-mgw-api org.osgi.service.blueprint.container.ComponentDefinitionException: Unable to load class org.codehaus.jackson.jaxrs.JacksonJsonProvider from recipe BeanRecipe[name='jsonProvider']

I have already added the correct dependency to my pom.xml

    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-jaxrs</artifactId>
        <version>1.9.13</version>
    </dependency>

There must be something simple I am missing here, but I have spend many hours to figure it out now and I am getting nowhere. Does anybody know what I am doing wrong here?

I have provided my code below here.

Service interface:

@Path("/auth/")
public interface AuthService {

    @POST
    @Path("/login")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    Response login(LoginRequest loginRequest);

    @GET
    @Path("/person/get/{id}/")
    @Produces("application/xml")
    Response getPerson(@PathParam("id") String id);

    @DELETE
    @Path("/person/delete/{id}")
    void deletePerson(@PathParam("id") String id);
}

Request model:

@XmlRootElement(name="Login")
public class LoginRequest {
    private String username;
    private String password;
    private int loginType;

    public LoginRequest(String username, String password) {
        this.username = username;
        this.password = password;
        this.loginType = 1;
    }

    public LoginRequest() {
    }
}

Blueprint.xml

<blueprint
        xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"

You should change in the blueprint the tag to jaxrs like this:

<jaxrs:server id="endpoint1">
    <jaxrs:providers>
        <bean class="org.codehaus.jackson.jaxrs.JacksonJsonProvider"/>
    </jaxrs:providers>
</jaxrs:server>
