Enable password-less SSH login

To enable password-less login, generate a new SSH key with an empty passphrase:

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

Test this with:
     ssh localhost

If successful, you should not have to type in a new password.

Hence sequence generator is set up for the field id of table. The respective entity mapping for 'id' should be changed as below.     @Id        @GeneratedValue(strategy = GenerationType.IDENTITY)     @Basic(optional = false)     @NotNull     @Column(name = "id")     private Long id;     @SequenceGenerator(initialValue=1, sequenceName="INVOICE_SEQ",allocationSize=1,name="invoice_seq_name")     @GeneratedValue(generator="invoice_s...
