public class WorkManagerTaskExecutor extends JndiLocatorSupport implements SchedulingTaskExecutor, WorkManager, InitializingBean
WorkManager interface,
which either needs to be specified as reference or through the JNDI name.
This is the central convenience class for setting up a CommonJ WorkManager in a Spring context.
Also implements the CommonJ 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 CommonJ WorkManager interface.
The CommonJ WorkManager will usually be retrieved from the application server's JNDI environment, as defined in the server's management console.
Note: At the time of this writing, the CommonJ WorkManager facility is only supported on IBM WebSphere 6.0+ and BEA WebLogic 9.0+, despite being such a crucial API for an application server. (There is a similar facility available on WebSphere 5.1 Enterprise, though, which we will discuss below.)
On JBoss and GlassFish, a similar facility is available through
the JCA WorkManager. See the
JBossWorkManagerTaskExecutor
GlassFishWorkManagerTaskExecutor
classes which are the direct equivalent of this CommonJ adapter class.

Alternatively, you can also specify the JNDI name of the target WorkManager.
setWorkManagerName(java.lang.String)public void setWorkManagerName(String workManagerName)
This can either be a fully qualified JNDI name, or the JNDI name relative to the current environment naming context if "resourceRef" is set to "true".
public void setWorkListener(WorkListener workListener)
This shared WorkListener instance will be passed on to the
WorkManager by all execute(java.lang.Runnable) calls on this TaskExecutor.
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 call might return immediately if the implementation uses an asynchronous execution strategy, or might block in the case of synchronous execution.
