The easiest way to create a Client is to call ClientBuilder.newClient() . It instantiates a
preinitialized Client that you can use right away. To fine-tune the construction of your Cli-
ent interfaces, the newBuilder() method creates a ClientBuilder instance that allows you
to register components and set configuration properties. It inherits these capabilities by im-
plementing the Configurable interface:

package package javax . ws . rs . core ;

public public interface interface Configurable Configurable < C extends extends Configurable > {

public public C property ( String name , Object value );

public public C register ( Class <?> componentClass );

public public C register ( Object component );

...

}
