Description Stephen DiMilla 2011-12-09 08:35:37 EST

Build Identifier: eclipselink-2.3.0.v20110604-r9504

Using the entities:

@Entity
@Table(name="CUSTOMER_TABLE")
public class Customer implements java.io.Serializable
{

    // Instance variables
    private String id;
    private String name;
    public Customer()
    {
    }

    public Customer (String id, String name)
    {
    this.id = id;
    this.name = name;
    }
   @Id
    @Column(name="ID")
    public String getId() {
    return id;
    }
    public void setId(String v) {
    this.id = v;
    }

    @Column(name="NAME")
    public String getName() {
    return name;
    }
    public void setName(String v) {
    this.name = v;
    }
}

--------------------
@Entity
@Table(name="ORDER_TABLE")
public class Order implements java.io.Serializable
{


    // Instance variables
    private String id;
    private double totalPrice;

    public Order()
    {
    }

    public Order (String id, double totalPrice)
    {
        this.id = id;
        this.totalPrice = totalPrice;
    }

    public Order (String id)
    {
        this.id = id;
    }

    @Id
    @Column(name="ID")
    public String getId() {
	return id;
    }
    public void setId(String id) {
	this.id = id;
    }

    @Column(name="TOTALPRICE")
    public double getTotalPrice() {
	return totalPrice;
    }
    public void setTotalPrice(double price) {
	this.totalPrice = price;
    }

Using the client code:

CriteriaBuilder cbuilder = getEntityManager().getCriteriaBuilder();
et.begin();
CriteriaQuery<Tuple> cquery = cbuilder.createTupleQuery();
Root<Customer> customer = cquery.from(Customer.class);

System.out.println("Use Tuple Query");
cquery.multiselect(customer.get("id"), customer.get("name"));
TypedQuery<Tuple> tq = getEntityManager().createQuery(cquery);

List<Tuple> result = tq.getResultList();

Tuple t = result.get(0);
 System.out.println("Testing valid index");
 System.out.println("value:" + t.get(1, String.class));

System.out.println("Testing invalid index");
try {
        t.get(99, String.class);
        System.out.println("Did not get expected IllegalArgumentException for
invalid index:" + t.get(99, String.class));
} catch (IllegalArgumentException iae) {
        System.out.println("Got expected IllegalArgumentException");
} catch (Exception e) {
        System.out.println("Received unexpected exception", e);
}
