Getting started Jersey.
1. Project build and management configuration is described in the pom.xml located in the project root
directory.
REF : pom elements
2. Project sources are located under src/main/java.
3. Project resources are located under src/main/resources.
4. Project web application files are located under src/main/webapp.
5. To compile and package the application into a WAR, invoke the following maven command in your
console:
ex : mvn clean package
logs :
Packaging webapp
[INFO] Assembling webapp [simple-service-webapp] in [.../simple-service-webapp/target/[INFO] Processing war project
[INFO] Building war: .../simple-service-webapp/target/simple-service-webapp.war
Now you are ready to take the packaged WAR (located under ./target/simple-servicewebapp.
war) and deploy it to a Servlet container of your choice.

6. Root Resource Classes
Root resource classes are POJOs (Plain Old Java Objects) that are annotated with @Path
7. @Produces
annotation is used to specify the MIME media types of representations a resource can produce and send back to the
client.
Using multiple output MIME types
@Produces({"application/xml", "application/json"})
@Consumes
annotation is used to specify the MIME media types of representations that can be consumed by a resource.
@QueryParam
is used to extract query parameters from the Query component of the request URL.
@DefaultValue
annotation, will be assigned to the step method parameter. If the
"step" value cannot be parsed as a 32 bit signed integer then a HTTP 404
ex :
public Response smooth(
4 @DefaultValue("2") @QueryParam("step") int step
@FormParam
it extracts information from a request representation that is of the MIME media type
"application/x-www-form-urlencoded"
@Context HttpHeaders headers,
@Singleton
annotation says that the resource
will be managed as singleton and not in request scope. The sub-resource locator method returns a class which means that the runtime will managed the resource instance and its life-cycle. If the method would return instance instead, the Singleton annotation would have no effect and the returned instance would be used.
