java.lang.Objectorg.springframework.jndi.JndiAccessor
org.springframework.jndi.JndiLocatorSupport
org.springframework.jca.work.WorkManagerTaskExecutor
public class WorkManagerTaskExecutor
TaskExecutor implementation
that delegates to a JCA 1.5 WorkManager, implementing the
WorkManager interface.
This is mainly intended for use within a JCA ResourceAdapter implementation, but may also be used in a standalone environment, delegating to a locally embedded WorkManager implementation (such as Geronimo's).
Also implements the JCA 1.5 WorkManager interface itself, delegating all calls to the target WorkManager. Hence, a caller can choose whether it wants to talk to this executor through the Spring TaskExecutor interface or the JCA 1.5 WorkManager interface.
This adapter is also capable of obtaining a JCA WorkManager from JNDI.
This is for example appropriate on the Geronimo application server, where
WorkManager GBeans (e.g. Geronimo's default "DefaultWorkManager" GBean)
can be linked into the J2EE environment through "gbean-ref" entries
in the geronimo-web.xml deployment descriptor.
On JBoss and GlassFish, obtaining the default JCA WorkManager
requires special lookup steps. See the
JBossWorkManagerTaskExecutor
GlassFishWorkManagerTaskExecutor
classes which are the direct equivalent of this generic JCA adapter class.

This shared WorkListener instance will be passed on to the

public void afterPropertiesSet()
throws NamingException
InitializingBeanThis method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

The default implementation returns a SimpleTaskWorkManager.
Can be overridden in subclasses.
public void execute(Runnable task)
TaskExecutortask.
The call might return immediately if the implementation uses an asynchronous execution strategy, or might block in the case of synchronous execution.

public void execute(Runnable task,
long startTimeout)
AsyncTaskExecutortask.
execute in interface AsyncTaskExecutortask - the Runnable to execute (never null)startTimeout - the time duration (milliseconds) within which the task is
supposed to start. This is intended as a hint to the executor, allowing for
preferred handling of immediate tasks. Typical values are AsyncTaskExecutor.TIMEOUT_IMMEDIATE
or AsyncTaskExecutor.TIMEOUT_INDEFINITE (the default as used by TaskExecutor.execute(Runnable)).public Future<?> submit(Runnable task)
