415 Error when posting JSON in Java with Jersey

Question

I have looked through Google, and at other questions here, to no avail. They all say the same things... Import the .jar for jersey-json (done), add the dependency to pom.xml (done) and add the POJOMappingFeature to the web.xml (done), yet I am still unable to access the Restful web service with JSON going into, or coming out of the server.

web.xml

        <groupId>com.sun.jersey</groupId>
        <artifactId>jersey-json</artifactId>
        <version>1.8</version>
    </dependency>

Service method:

@POST
@Path("/request")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public ResponseInfo Request(RequestInfo requestInfo)

Both ResponseInfo and RequestInfo have @XmlRoot and @XmlElement annotations. I am running locally on Tomcat 7.0.33 and get the following error:

Did you forget to include the HTTP verb on your service method, or do you not have one in the actual code as well? — Perception, Dec 10 '12 at 23:06

It seems you are missing JacksonJsonProvider.class for marshalling and unmarshalling that can be found in jackson-core-asl-1.9.2.jar

You might need to add an ObjectMapper class. For example in my Jersey-Java sample app, when my client wants to create an account, this is the logic that is run on the server:

@Path("/makeStormpathAccount")
public class StormpathAccount {

    @POST
    public void createAccount(UserAccount userAccount) throws Exception {

Notice how I have (UserAccount userAccount) as the parameters of my route method. The UserAccount class looks like this:

import org.codehaus.jackson.annotate.JsonProperty;

public class UserAccount {

    @JsonProperty
    private String first_name;

    @JsonProperty
    private String last_name;

    @JsonProperty
    private String user_name;

    @JsonProperty
    private String email;

    @JsonProperty
    private String password;


    public String getFirstName() {
        return first_name;
    }

    public String getLastName() {
        return last_name;
    }

    public String getUserName() {
        return user_name;
    }

    public String getEmail() {
        return email;
    }

    public String getPassword() {
        return password;
    }
}

and it uses this ObjectMapper class to actually map the data:

import org.codehaus.jackson.map.ObjectMapper;
import org.codehaus.jackson.map.SerializationConfig;

import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

@Provider
public class MyObjectMapperProvider implements ContextResolver<ObjectMapper> {

    final ObjectMapper defaultObjectMapper;

    public MyObjectMapperProvider() {
        defaultObjectMapper = createDefaultMapper();
    }

    @Override
    public ObjectMapper getContext(Class<?> type) {
        return defaultObjectMapper;
    }

    private static ObjectMapper createDefaultMapper() {
        final ObjectMapper result = new ObjectMapper();
        result.configure(SerializationConfig.Feature.INDENT_OUTPUT, true);

        return result;
    }

}

to convert the JSON being sent from the client, straight into Java!

Try adding Genson library to your classpath. It is a java library doing conversion between java and json. It works quite well with Jersey. You only need to drop the jar into your classpath.

I was facing the same problem, and changing @XmlElement to @XmlRootElement in RequestInfo solved my problem.

import javax.xml.bind.annotation.XmlRootElement;
