I use hibernate end annotation. My bean :
[quote]
public void setId_material(final int material)
{
this.id_material = material;
}
@Column(name = "ID_MATERIAL", nullable = false, precision = 0)
@Id
public int getId_material()
{
return this.id_material;
}
[/quote]

These code above throws :
[list]
Exception in thread "main" org.hibernate.MappingException: Same logical column name referenced several times: Material.id_material Id_Material id_material
at org.hibernate.cfg.Mappings.addColumnBinding(Mappings.java:457)
at org.hibernate.cfg.Ejb3Column.addColumnBinding(Ejb3Column.java:257)
at org.hibernate.cfg.Ejb3Column.linkWithValue(Ejb3Column.java:250)
[/list]

where's the problem ??

thanks in advance
