Jeffrey JonesJeffrey Jones has pleaded guilty to charges stemming from a 2003 sex offender case.

Jones, who played Principle Rooney in 'Ferris Bueller's Day Off,' admitted to failing to update his sex offender registration, TMZ reports.

As a result of his plea, he's been sentenced to three years formal probation and 250 hours of community service.

The actor, 64, was ordered in 2003 to register as a sex offender after pleading no contest to a felony charge of inducing a 14-year-old boy to pose for nude photos at his Hollywood Hills home.

According to court records, Jones employed the boy several times, beginning in 2000, and coaxed him to pose in various situations, including with a cowboy hat and as a Native American.
