Class EJB3InvokerJob

java.lang.Object

org.quartz.jobs.ee.ejb.EJBInvokerJob

org.quartz.jobs.ee.ejb.EJB3InvokerJob

All Implemented Interfaces:

Job

public class EJB3InvokerJob
extends EJBInvokerJob

A Job that invokes a method on an EJB3.

Expects the properties corresponding to the following keys to be in the JobDataMap when it executes:

• EJB_JNDI_NAME_KEY- the JNDI name (location) of the EJB's home interface.
• EJB_METHOD_KEY- the name of the method to invoke on the EJB.
• EJB_ARGS_KEY- an Object[] of the args to pass to the method (optional, if left out, there are no arguments).
• EJB_ARG_TYPES_KEY- an Class[] of the types of the args to pass to the method (optional, if left out, the types will be derived by calling getClass() on each of the arguments).

The following keys can also be used at need:

• INITIAL_CONTEXT_FACTORY - the context factory used to build the context.
• PROVIDER_URL - the name of the environment property for specifying configuration information for the service provider to use.

The result of the EJB method invocation will be available to Job/TriggerListeners via JobExecutionContext.getResult().

Method Detail

execute

public void execute(JobExecutionContext context)
             throws JobExecutionException

Description copied from interface: Job

Called by the Scheduler when a Trigger fires that is associated with the Job.

The implementation may wish to set a result object on the JobExecutionContext before this method exits. The result itself is meaningless to Quartz, but may be informative to JobListeners or TriggerListeners that are watching the job's execution.

Specified by:

execute in interface Job

Overrides:

execute in class EJBInvokerJob

Throws:

JobExecutionException - if there is an exception while executing the job.
