Answer 1

Adding to the answer, if you are using jackson then dependency is already mentioned as jersey-media-json-jackson -

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <version>${jersey.version}</version>
</dependency>

There are other json providers as well.

If you want to use MOXy as your JAXB implementation, then you can use

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-moxy</artifactId>
    <version>${jersey.version}</version>
</dependency>

To use JSON-P as your JSON provider you need to add

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-processing</artifactId>
    <version>${jersey.version}</version>
</dependency>

To use Jettison as your JSON provider you need to add jersey-media-json-jettison module to your pom.xml file:

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jettison</artifactId>
    <version>${jersey.version}</version>
</dependency>

To use multipart features you need to add jersey-media-multipart module to your pom.xml file:

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>${jersey.version}</version>
</dependency>
