Hi,
I use JBoss Seam 1.2.1 GA, Jboss 4.0.5 GA and JSF for one project. I have made
one new Session bean for inserting/deleting some data in/from database.
It's look something like this:
|
| @Stateless
| @Name("initialize")
| public class InitializeData implements Initialize
| {
| @PersistenceContext
| private EntityManager em = null;
|
| public void insertData()
| {
| try
| {
|
| PriceCategory cat1 = new PriceCategory("Old", new
BigDecimal(3.2));
| PriceCategory cat2 = new PriceCategory("New", new
BigDecimal(5.2));
|
| em.persist(cat1);
| em.persist(cat2);
|
| em.flush();
| }
| catch(Exception e)
| {
| e.printStackTrace();
| }
| }
|
But when I call this method from JSF, I get always this exception by first
em.persist()-call:
|
| 09:27:45,078 INFO [STDOUT] Hibernate: insert into PriceCategory
(priceCategoryId, name, dailyFee, optLock) values (null, ?, ?, ?)
| 09:27:45,093 WARN [JDBCExceptionReporter] SQL Error: -104, SQLState: 23000
| 09:27:45,093 ERROR [JDBCExceptionReporter] Unique constraint violation:
SYS_CT_61 in statement [insert into PriceCategory (priceCategoryId, name,
dailyFee, optLock) values (null, ?
| , ?, ?)]
| 09:27:45,093 ERROR [STDERR] javax.persistence.EntityExistsException:

| 09:27:45,093 ERROR [STDERR] at
org.hibernate.ejb.AbstractEntityManagerImpl.persist(AbstractEntityManagerImpl.java:218)
|
|
I don't really understand what happend there. Perheps my entity bean
PriceCategory:
|
| @Entity
| @Table(name = "PriceCategory")
| @Name("pricecategory")
| public class PriceCategory implements Serializable {
|
| @Id
| @GeneratedValue(strategy=GenerationType.IDENTITY)
| @Column(name = "priceCategoryId")
| private Integer id;
|
| @Column(name = "name", nullable = false, length = 20, unique=true)
| private String name;
|
| @Column(name = "dailyFee", nullable = false, precision = 4, scale = 2)
| private BigDecimal dailyFee;
|
| @Version
| @Column(name = "optLock")
| private Integer version;
| ...
|
|
I am really stuck at this point and without data in database cann't do anything
more.
Could anyone give me some hint for get over it?
Thanks a lot for every help!
