Jersey framework extensions

Let's start our discussions on Jersey with a baby step. If you want to use any Jersey-specific feature in an application, then you will have to add a dependency to the appropriate Jersey libraries. For instance, to use a Jersey configuration class such as org.glassfish.jersey.server.ResourceConfig in your application, you need to depend on the jersey-container-servlet JAR. If the consuming application uses Maven for building the source, then specifying a dependency to the jersey-container-servlet JAR in the Project Object Model (POM) file may look like the following:

<dependency> 
    <groupId>org.glassfish.jersey.containers</groupId> 
   
  <!-- module --> 
    <artifactId>jersey-container-servlet</artifactId> 
 
  <!-2.26: latest release version --> 
    <version>2.26</version> 
     
    <!-- container(GlassFish) provides dependency 
         for this example --> 
    <scope>provided</scope...
