method call converts the CustomerEntity instance found in the database into an instance of
the JAXB class Customer . This Customer instance is what is returned to the JAX-RS
runtime.

public public static static void void domain2entity ( CustomerEntity entity ,

Customer customer )

{

entity . setId ( customer . getId ());
entity . setFirstName ( customer . getFirstName ());
entity . setLastName ( customer . getLastName ());
entity . setStreet ( customer . getStreet ());
entity . setCity ( customer . getCity ());
entity . setState ( customer . getState ());
entity . setZip ( customer . getZip ());
entity . setCountry ( customer . getCountry ());

}

public public static static Customer entity2domain ( CustomerEntity entity )

{

Customer cust = new new Customer ();

cust . setId ( entity . getId ());
cust . setFirstName ( entity . getFirstName ());
cust . setLastName ( entity . getLastName ());
cust . setStreet ( entity . getStreet ());
cust . setCity ( entity . getCity ());
cust . setState ( entity . getState ());
cust . setZip ( entity . getZip ());
cust . setCountry ( entity . getCountry ());
return return cust ;

}

The domain2entity() and entity2domain() methods simply convert to and from the
JAXB and JPA class hierarchies.

public public Customers getCustomers ( int int start ,

int int size ,

String firstName ,
String lastName ,
UriInfo uriInfo )

{

UriBuilder builder = uriInfo . getAbsolutePathBuilder ();
builder . queryParam ( "start" , "{start}" );
builder . queryParam ( "size" , "{size}" );

ArrayList < Customer > list = new new ArrayList < Customer >();

ArrayList < Link > links = new new ArrayList < Link >();
