Let's build a simple OAuth 2.0 client using Jersey APIs to understand the API usage pattern.
The complete source code for this example is available on the Packt website. You can download the example from the Packt website link that we mentioned at the beginning of this book, in the Preface section. In the downloaded source code, take a look at the rest-chapter6-oauth2-webclient project.
To use the Jersey OAuth 2.0 client APIs in your application, you need to add a dependency to the oauth2-client JAR file. If you use Maven, the dependency entry in pom.xml may look as shown in the following lines:
<dependency> <groupId>org.glassfish.jersey.security</groupId> <artifactId>oauth2-client</artifactId> ...
