What’s New In Quartz Scheduler 2.2

We’d like to express thanks to the community contributors that provided ideas and patches for much of the work contained in this release!

API Changes with 2.2.0 (including some minor backward compatibility breakage)

QTZ-292 - Scheduler interface : in the method scheduleJobs , the triggers should be part of a Set instead of a List
QTZ-304 - Scheduler#scheduleJobs API change to support generics and avoid cast
QTZ-366 - Deleted the long-deprecated CloudscapeDelegate
QTZ-212 - Add schedulerStarting() method to SchedulerListener interface
QTZ-225 - Make the Scheduler’s ClassLoadHelper available to plugins when they are initialized
For those using JDBC JobStore, there is a schema change that requires the addition of a column to the fired_triggers table, you can add such with a SQL statement such as this (with slight variants on data type needed depending upon your database flavor):
- for oracle: ALTER TABLE QRTZ_FIRED_TRIGGERS ADD COLUMN SCHED_TIME NUMBER(13) NOT NULL;
- for postgresql: ALTER TABLE QRTZ_FIRED_TRIGGERS ADD COLUMN SCHED_TIME BIGINT NOT NULL;
- for MySql: ALTER TABLE QRTZ_FIRED_TRIGGERS ADD COLUMN SCHED_TIME BIGINT(13) NOT NULL;
- etc.

QTZ-370 - Ability to override default transaction timeout when beginning new UserTransaction
QTZ-323 - Ability to override worker thread names (when using SimpleThreadPool)
QTZ-79 - Improvements to the out-of-the-box SendMailJob
QTZ-121 - Create an EJB Job invoker that supports EJB3
QTZ-267 - Add new Scheduler method: scheduleJob(JobDetail job, Set trigger) to schedule multiple triggers for a job all at once.
QTZ-272 - Add initialize() to ConnectionProvider interface
QTZ-275 - Allow ‘triggerless’ initial storing of non-durable jobs.
QTZ-315 - Improvements for Job Recovery Information
QTZ-154 - OSGi support

The Quartz library is now distributed only as two jar files: one with all Quartz functionality, one with the out-of-the-box jobs (see QTZ-378)
Quartz now requires JDK 1.6 or newer (QTZ-286)
Performance improvements, including:
- Improvements to some select statements in JDBC JobStore
Some internal SPI/interface refactorings (cleanups) such as on DriverDelegate and its subclasses, the Semaphore class, etc.
