Examples for Chapter 7 - RESTful Java with JAX-RS 2.0 - page 296

Customer customer = client . target
( "http://localhost:8080/services/customers/1" )
. request (). get ( Customer . class );
System . out . println ( "Should never get here!" );

}
catch catch ( NotFoundException e )

{

System . out . println ( "Caught error!" );
String error = e . getResponse (). readEntity ( String . class );
System . out . println ( error );

}

}

When this client code runs, the server will throw a CustomerNotFoundException , which is
converted into a 404 response back to the client. The client code handles the error as dis-
cussed in Exception Handling and throws a javax.ws.rs.NotFoundException , which is
handled in the catch block. The error message is extracted from the HTTP error response and
displayed to the console.
