Hello I am creating an entity user which hold an compound primairy key. consisting of id and department_id. The department_id is set by the code but the id should be generated by the Table Generator. BUt this value stay -1. Can any one point me where it could go wrong. At the moment i have: @Entity @IdClass(UserEntityPk.class) @Table(name = "KIEKEBOE_USERS") public class UserEntity implements java.io.Serializable { @TableGenerator(name = "userIdGen", table = "KIEKEBOE_SEQUENCE_GENERATOR", pkColumnName = "GEN_KEY", valueColumnName = "GEN_VALUE", pkColumnValue = "USER_ID", initialValue = 203, allocationSize = 1) @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "userIdGen") @Column(name = "USER_ID", nullable = false) private int id = -1; @Id @Column(name = "DEP_ID", nullable = false) private int depId = -1; public int getId() { return id; } public int getDepId() { return depId; } The Pk class is: @Embeddable public class UserEntityPk implements Serializable { private int id = -1; private int depId = -1; public UserEntityPk() { super(); } @Id @Column(name = "DEP_ID", nullable = false) public int getDepId() { return depId; } @TableGenerator(name = "userIdGen", table = "KIEKEBOE_SEQUENCE_GENERATOR", pkColumnName = "GEN_KEY", valueColumnName = "GEN_VALUE", pkColumnValue = "USER_ID", initialValue = 203, allocationSize = 1) @Id @GeneratedValue(strategy = GenerationType.TABLE, generator = "userIdGen") @Column(name = "USER_ID", nullable = false) public int getId() { return id; } public void setDepId(int newDepId) { depId = newDepId; } public void setId(int newId) { id = newId; } } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4070135#...
