• Write a simple Consumer class that consumes the artist JSON using both JSON-B and JSON-P.

src/main/java/io/openliberty/guides/consumingrest/Consumer.java:

• Add a method that uses JSON-B to consume the REST service in the Consumer class:

src/main/java/io/openliberty/guides/consumingrest/Consumer.java:

• Add a method for consuming the REST service using JSON-P in the Consumer class:

src/main/java/io/openliberty/guides/consumingrest/Consumer.java:

• Now that you can consume a JSON resource you can put that data to use. Copy the ArtistResource class below and replace the ArtistResource class in the start directory.

src/main/java/io/openliberty/guides/consumingrest/service/ArtistResource.java:

• Create a test class, src/test/java/it/io/openliberty/guides/consumingrest/ConsumingRestTest.java.
