JPA @Column annotation does not work in JBoss5.x, MySQL [my

[harsharuthere]

@Column atttributes name and length does not work in JBoss5.x

here is the code:

@Entity
public class ColumnAttribsTesting {

 @Id
 @GeneratedValue(strategy=GenerationType.AUTO)
 private Integer id;

 private Integer column1 ;

 private Integer column2 ;

 public ColumnAttribsTesting() {

 }

 public Integer getId() {
 return id;
 }

 public void setId(Integer id) {
 this.id = id;
 }

 @Column(name = "abcde", length=1024)
 public Integer getColumn1() {
 return column1;
 }

 public void setColumn1(Integer column1) {
 this.column1 = column1;
 }

 public Integer getColumn2() {
 return column2;
 }

 public void setColumn2(Integer column2) {
 this.column2 = column2;
 }

}

persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"

<persistence-unit name="atspu" transaction-type="JTA">

<property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.JBossTransactionManagerLookup" />
</properties>
</persistence-unit>
</persistence>

it does not create a column with the name abcde, and the length is always defaults to 255 chars

i wonder how the basic annotation does not work..
sure i am doing something silly..


please help

hi the issue was resolved. it was my mistake

1. I used @Coulmn at the getters and @ManyTOOne at the field level.

2. Also, having a field length of 255 for integer is not correct

thanks,
