Chapter 2. Modules and dependencies

If you are using Glassfish application server, you don't need to package anything with your application, everything is already included. You just need to declare (provided) dependency on JAX-RS API to be able to compile your application.

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0.1</version>
    <scope>provided</scope>
</dependency>

If you are using any Jersey specific feature, you will need to depend on Jersey directly.

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22</version>
    <scope>provided</scope>
</dependency>
<!-- if you are using Jersey client specific features without the server side -->
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.22</version>
    <scope>provided</scope>
</dependency>
            

Following dependencies apply to application server (servlet containers) without any integrated JAX-RS implementation. Then application needs to include JAX-RS API and Jersey implementation in deployed application.

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <!-- if your container implements Servlet API older than 3.0, use "jersey-container-servlet-core"  -->
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22</version>
</dependency>
<!-- Required only when you are using JAX-RS Client -->
<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.22</version>
</dependency>

Applications running on plain JDK using only client part of JAX-RS specification need to depend only on client. There are various additional modules which can be added, like for example grizzly or apache or jetty connector (see dependencies snipped below). Jersey client runs by default with plain JDK (using HttpUrlConnection). See Chapter 5, Client API. for more details.

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-client</artifactId>
    <version>2.22</version>
</dependency>
            

Currently available connectors:

<dependency>
    <groupId>org.glassfish.jersey.connectors</groupId>
    <artifactId>jersey-grizzly-connector</artifactId>
    <version>2.22</version>
</dependency>

<dependency>
    <groupId>org.glassfish.jersey.connectors</groupId>
    <artifactId>jersey-apache-connector</artifactId>
    <version>2.22</version>
</dependency>

<dependency>
    <groupId>org.glassfish.jersey.connectors</groupId>
    <artifactId>jersey-jetty-connector</artifactId>
    <version>2.22</version>
</dependency>

Apart for a standard JAX-RS Servlet-based deployment that works with any Servlet container that supports Servlet 2.5 and higher, Jersey provides support for programmatic deployment to the following containers: Grizzly 2 (HTTP and Servlet), JDK Http server, Simple Http server and Jetty Http server. This chapter presents only required maven dependencies, more information can be found in Chapter 4, Application Deployment and Runtime Environments.
