Quartz can be used in Mule applications to schedule events. An inbound Quartz endpoint triggers events that can be repeated, like every second. Outbound Quartz endpoints schedule existing events to fire at later dates. Cron expressions define schedules and events can be persisted in a database. Jobs perform actions when time triggers occur from the Quartz transport. For example, a Mule flow can be configured to write a file to an outbound endpoint at a specific interval defined by a Quartz scheduler.

1. QUARTZ IN MULE

2. Quartz transport can be used in Mule application to schedule an event to take place.
An inbound quartz endpoint can be used to trigger inbound events that can be repeated,
such as every second. Outbound quartz endpoints can be used to schedule an existing event
to fire at a later date. Users can create schedules using cron expressions, and events can be
persisted in a database.

3. Cron Expressions: A cron expression is a string comprised by six or seven fields separated
by white space. Fields can contain any of the allowed values, along with various
combinations of the allowed special characters for that field.
We can use cron expressions to create schedulers
Example of cron expression :
Cron expressions can be as simple as this:
* * * * ? *
or more complex, like this:
0 0/5 14,18,3-39,52 ? JAN,MAR,SEP MON-FRI 2002-2010.

4. Jobs :- Jobs are used to perform an action when a time trigger occurs from the Quartz
transport. Mule provides a number of jobs for generating and scheduling events.

5. Now let’s test an application with Quartz

6. Let’s suppose we have a simple application designed to write a file to an
outbound endpoint at a specific interval of time as follow :-

7. The mule config will be as follow :-
As you can see the flow is designed to write a file to a folder at a specific
interval of time

8. We start and run our application as follow:-
We can find the application has start working and the Quartz is making the
flow to write the file in the outbound endpoint after each specific interval of
time

9. In the outbound folder you can see the files are generated at each
interval of time:-

10. In my next slide I will bring some other techniques in Mule
implementation .
Hope you have enjoyed this simpler version.
