Jersey always produces Status 415 when I use POSTMAN with x-www-urlencoded! Why?

I'm trying to learn Jersey, Java's REST framework based on the Jax RS specification. I'm doing a tutorial from pluralsite which isn't that great. But anyway, I've gotten to a point where I'm using Google Chromes postman to submit url encoded form parameters to my service. The class I'm using for my resource methods is called ActivityResource. Every @GET annotated method works but not the @POST method. The path I'm submitting is localhost:8080//webapi/activities/activity No matter what, if i insert a slash in front of either path parameter, rearrange the annotation headers or apply the old fashioned "application/x-www-form-urlencoded" argument I always get a rotten HTTP Status 415 - Usupported Media Type response. Does anyone have any idea what I'm missing. Is there a missing jar that I need? @Path("activities") public class ActivityResource { ``` private ActivityRepository activityRepository = new ActivityRepositoryStub(); @POST @Path("activity") @Consumes(MediaType.APPLICATION_FORM_URLENCODED) @Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML}) public Activity createActivityParams(MultivaluedHashMap<String, String> formParams) { System.out.println(formParams.getFirst("description")); System.out.println(formParams.getFirst("duration")); Activity activity = new Activity(); activity.setDescription(formParams.getFirst("description")); activity.setDuration(Integer.parseInt( formParams.getFirst("duration"))); String id = String.valueOf( activityRepository.findAllActivities().size() ); activity.setId(id); activityRepository.findAllActivities().add(activity); return activity; } .....My Get methods down here which actually output functioning results ``` } Here is my POM file http://maven.apache.org/maven-v4_0_0.xsd"> ``` <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>simple-service-webapp</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>simple-service-webapp</name> <build> <finalName>simple-service-webapp</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.5.1</version> <inherited>true</inherited> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> </build> <dependencyManagement> <dependencies> <dependency> <groupId>org.glassfish.jersey</groupId> <artifactId>jersey-bom</artifactId> <version>${jersey.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.glassfish.jersey.containers</groupId> <artifactId>jersey-container-servlet-core</artifactId> <!-- use the following artifactId if you don't need servlet 2.x compatibility --> <!-- artifactId>jersey-container-servlet</artifactId --> </dependency> <dependency> <groupId>org.glassfish.jersey.media</groupId> <artifactId>jersey-media-moxy</artifactId> <version>2.1</version> </dependency> <!-- <dependency> <groupId>org.glassfish.jersey.core</groupId> <artifactId>jersey-client</artifactId> <version>2.5.1</version> <scope>provided</scope> </dependency> --> </dependencies> <properties> <jersey.version>2.5.1</jersey.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> ```
