It's just one of my first demos on JPA and it's so simple that this error drives me crazy:(
CREATE TABLE "Order"
(
"Id" integer NOT NULL,
"DateOf" timestamp with time zone,
"Description" text,
CONSTRAINT "PK_Id" PRIMARY KEY ("Id" )
)
CREATE TABLE "LineItem"

"OrderId" integer,
"Cost" money,
CONSTRAINT "LineItem_Id" PRIMARY KEY ("Id" ),
CONSTRAINT "LineItem_OrderId_fkey" FOREIGN KEY ("OrderId")
REFERENCES "Order" ("Id") MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)

I think that the name of the tables and columns in your create Table statements should not be quoted. Have you tried with the following create Table Statements?
CREATE TABLE Order
(
Id integer NOT NULL,
DateOf timestamp with time zone,
Description text,
CONSTRAINT PK_Id PRIMARY KEY (Id )
)
CREATE TABLE LineItem
(
Id oid NOT NULL,
OrderId integer,
Cost money,
CONSTRAINT LineItem_Id PRIMARY KEY (Id ),
CONSTRAINT LineItem_OrderId_fkey FOREIGN KEY (OrderId)
REFERENCES Order (Id) MATCH SIMPLE
ON UPDATE NO ACTION ON DELETE NO ACTION
)
** EDIT I Didn't review the mappings **
I think that the mappings of columns with escapes are being ignored. Also, try to change the mappings with the following:
@Entity
@Table(name="Order")
@XmlRootElement(name="Order")
public class Order implements Serializable {
private static final long serialVersionUID = 1L;
@Id @GeneratedValue
@Column(name="Id")
public int Id;
@Column(name="DateOf")
public java.util.Date DateOf;
@Column(name="Description")
public String Description;
@OneToMany(cascade=CascadeType.REMOVE, mappedBy="order")
public List<LineItem> Items;
}
@Entity
@Table(name="LineItem")
public class LineItem implements Serializable {
private static final long serialVersionUID = 1L;
@Id @GeneratedValue
@Column(name="Id")
public int Id;
@ManyToOne(cascade=CascadeType.REMOVE)
@JoinColumn(name="OrderId", referencedColumnName="Id")
public Order order;
}
