AI explanation

Quartz is a Java job-scheduling library that uses cron expressions (extended cron syntax with seconds precision) to define when triggers should fire scheduled jobs. JSTL is a JSP tag library, iBatis is a persistence/ORM framework, and AOP is a programming paradigm for cross-cutting concerns — none of them involve cron-style scheduling.
