Hi,
I have two class Voucher and TDTransaction , Voucher calss contain an object of TDTransaction . I have to store data of Voucher to app_voucher table and TDTransaction to app_tdtransaction , for that i coded Voucher class as below

@Entity
@Table(name="app_voucher")
public class Voucher {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="VOUCHER_ID")
private long voucherId;

@Embedded
@JoinTable(
name="dms_tds_transaction",
joinColumns = @JoinColumn(name="VOUCHER_ID")
private TDTransaction tdsTransaction=new TDTransaction();

}

and TDTransactio

@Embeddable
@Table(name="app_tdtransaction")
public class TDTransaction {

@ManyToOne(targetEntity=AccountHead.class)
@JoinColumn(name="ID")
private AccountHead tdsAccountHead;

}

I getting an exception while saving voucher object.
Exception is MySQLSyntaxErrorException - Unknown column 'ID' in 'field list'
But the column ID is there in my table.
Please correct me if the mapping is wrong

thanks and regards
Ajil
