JAX-RS with Jersey

I use Jersey as the JAX-RS implementation.

Up to Jersey 2.25, Java 6 and JAX-RS 2.0 (JSR-339) are required.

As of Jersey 2.26, there are important changes :

  • Requires Java 8

  • Use JAX-RS 2.1 (JSR-370)

Docker

Build an image

docker build -t jaxrs-sample-jersey .

Run a container

docker run -d –name jaxrs-test-1 -p 8090:8080 jaxrs-sample-jersey

Test

Or try :

curl -X GET http://localhost:8090/jaxrs-sample-jersey/webapi/myresource[http://localhost:8090/jaxrs-sample-jersey/webapi/myresource]
