Assert . assertEquals ( 204 , response . getStatus ());
response . close ();

}

If there is a cancel link relationship, the client posts an empty message to this URL to can-
cel the order:

System . out . println ();
System . out . println ( "** New list of orders after cancel: " );
orderList = client . target ( orders ). request (). get ( String . class );
System . out . println ( orderList );

The client does another GET /orders to show that the state of our created order was set to
cancelled:

System . out . println ();
System . out . println ( "** Purge cancelled orders at URL: "
+ purge . getUri (). toString ());
response = client . target ( purge ). request (). post ( null null );

Assert . assertEquals ( 204 , response . getStatus ());
response . close ();

System . out . println ();
System . out . println ( "** New list of orders after purge: " );
orderList = client . target ( orders ). request (). get ( String . class );
System . out . println ( orderList );

}

Finally, by posting an empty message to the purge link, the client cleans the order entry
database of any cancelled orders.
