Thee "status" variable was set nullable=false and set not null in database
what was I have to do?
please help me.....

The error message is pretty clear on what happned.

You tried to persist/merge an Alumni into your database but the value of the status attribute on your instance was null.

If Hibernate did not throw this error you would have gotten a DB rule violation and your insert/update would have failed.

Try logging out the value of this field before you ask Hibernate to update/persist it and make sure the value is set.
