JPA primary key auto generate

My primary key entity looks like below

@GeneratedValue(strategy= GenerationType.TABLE)
private Long id;

When I run, I get the error

could not get or update next value;nested exception is org.hibernate.exception.SQLGrammerException:could not get or update next value

but when I just change to

@GeneratedValue 
private Long id;

no error is thrown. I want to generate unique primary key per table on oracle db.
