org.springframework.jca.work .SimpleTaskWorkManager

SimpleTaskWorkManager

public class SimpleTaskWorkManager implements WorkManager(Code)

Simple JCA 1.5 javax.resource.spi.work.WorkManager implementation that delegates to a Spring org.springframework.core.task.TaskExecutor . Provides simple task execution including start timeouts, but without support for a JCA ExecutionContext (i.e. without support for imported transactions).

Uses a org.springframework.core.task.SyncTaskExecutor for SimpleTaskWorkManager.doWork calls and a org.springframework.core.task.SimpleAsyncTaskExecutor for SimpleTaskWorkManager.startWork and SimpleTaskWorkManager.scheduleWork calls, by default. These default task executors can be overridden through configuration.

NOTE: This WorkManager does not provide thread pooling by default! Specify a org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor (or any other thread-pooling TaskExecutor) as "asyncTaskExecutor" in order to achieve actual thread pooling.

This WorkManager automatically detects a specified org.springframework.core.task.AsyncTaskExecutor implementation and uses its extended timeout functionality where appropriate. JCA WorkListeners are fully supported in any case.

Method Detail

doWork
public void doWork(Work work) throws WorkException(Code)

doWork
public void doWork(Work work, long startTimeout, ExecutionContext executionContext, WorkListener workListener) throws WorkException(Code)

executeWork
protected long executeWork(TaskExecutor taskExecutor, Work work, long startTimeout, boolean blockUntilStarted, ExecutionContext executionContext, WorkListener workListener) throws WorkException(Code)
	Execute the given Work on the specified TaskExecutor. Parameters: taskExecutor - the TaskExecutor to use Parameters: work - the Work to execute Parameters: startTimeout - the time duration within which the Work is supposed to start Parameters: blockUntilStarted - whether to block until the Work has started Parameters: executionContext - the JCA ExecutionContext for the given Work Parameters: workListener - the WorkListener to clal for the given Work the time elapsed from Work acceptance until start of execution(or -1 if not applicable or not known) throws: WorkException - if the TaskExecutor did not accept the Work

scheduleWork
public void scheduleWork(Work work) throws WorkException(Code)

scheduleWork
public void scheduleWork(Work work, long startTimeout, ExecutionContext executionContext, WorkListener workListener) throws WorkException(Code)

setAsyncTaskExecutor
public void setAsyncTaskExecutor(TaskExecutor asyncTaskExecutor)(Code)
	Specify the TaskExecutor to use for asynchronous work execution (i.e. SimpleTaskWorkManager.startWork and SimpleTaskWorkManager.scheduleWork calls). This will typically (but not necessarily) be an org.springframework.core.task.AsyncTaskExecutor implementation. Default is a org.springframework.core.task.SimpleAsyncTaskExecutor .

setSyncTaskExecutor
public void setSyncTaskExecutor(TaskExecutor syncTaskExecutor)(Code)
	Specify the TaskExecutor to use for synchronous work execution (i.e. SimpleTaskWorkManager.doWork calls). Default is a org.springframework.core.task.SyncTaskExecutor .

startWork
public long startWork(Work work) throws WorkException(Code)

startWork
public long startWork(Work work, long startTimeout, ExecutionContext executionContext, WorkListener workListener) throws WorkException(Code)
