Look at line 72. You're exeuting the following SQL statement:
INSERT INTO OHRI VALUES (id ,title , author)
Note that you are
not filling in the values of the variables id, title and author; instead, you're executing a statement which literally contains the names of the variables "id", "title" and "author". That's not going to work - the database is not going to understand what these words mean.
You should use a PreparedStatement instead and set the values before you execute the statement.
