Examples of TaskService

ca.eandb.jdcp.remote.TaskService
A remote service used by workers to perform tasks for ParallelizableJobs. @author Brad Kimmel
com.founder.fix.fixflow.core.TaskService
com.sun.sgs.service.TaskService
This Service provides facilities for scheduling tasks to run after the current task completes. The methods inherited from TaskManager schedule durable, transactional tasks. The scheduleNonDurableTask methods defined here are used to schedule tasks that are not persisted by the TaskService but optionally invoked in a transactional context.
By default all tasks scheduled will be owned by the calling task's owning identity. To create a new owning identity for a task use the RunWithNewIdentity annotation as described in the docs for TaskManager. @see TaskManager
org.activiti.engine.TaskService

org.drools.task.service.TaskService
org.eclipse.orion.internal.server.core.tasks.TaskService
A concrete implementation of the {@link ITaskService}.

org.jbpm.task.service.TaskService
org.kie.api.task.TaskService
org.restlet.service.TaskService
Application service capable of running and scheduling tasks asynchronously. The service instance returned will not invoke the runnable task in the current thread.

In addition to allowing pooling, this method will ensure that the threads executing the tasks will have the thread local variables copied from the calling thread. This will ensure that call to static methods like {@link Application#getCurrent()} still work.

Also, note that this executor service will be shared among all Restlets and Resources that are part of your context. In general this context corresponds to a parent Application's context. If you want to have your own service instance, you can use the {@link TaskService#wrap(ScheduledExecutorService)}method to ensure that thread local variables are correctly set. @author Jerome Louvel @author Doug Lea (docs of ExecutorService in public domain) @author Tim Peierls
org.wicketstuff.progressbar.spring.TaskService

Should be registered as SESSION scoped bean to prevent memory leaks with unfinished tasks.
