Asynchronous thread problem
I meet a thread problem:
I have a data processing management page.When user press the button, one data process begins.
The process takes more than 10 minutes,but when it runs for about 5 minutes, an exception throws:
2009-04-16 15:41:39,928 INFO [org.jboss.seam.async.QuartzDispatcher] In the scheduleInvocation() 2009-04-16 15:41:39,928 INFO [org.jboss.seam.async.QuartzDispatcher] In the scheduleWithQuartzService() 2009-04-16 15:41:39,932 INFO [org.jboss.seam.async.QuartzDispatcher] End executing Quartz job 2009-04-16 15:41:39,940 INFO [org.jboss.seam.async.QuartzDispatcher] Start executing Quartz job ...

These are my code segments,from the html to java:
1.
<h:commandButton action="#{permeabilitystatList.permeabilityWeekCollect}" value="OK"/>
2. PermeabilityStatListBean
@Stateful
@Scope(ScopeType.SESSION)
@Name("permeabilitystatList")
public class PermeabilityStatListBean implements PermeabilityStatList {
@In(required=false)
PermeabilityWeekCollect permeabilityWeekCollectThread;
....
public void permeabilityWeekCollect()
{
....
permeabilityWeekCollectThread.permeabilityWeekCollect("",branchObject, weekscope); //RUN IN A THREAD
....
}
3.
@Stateless
@Name("permeabilityWeekCollectThread")
@AutoCreate
public class PermeabilityWeekCollectThread implements PermeabilityWeekCollect{
@PersistenceContext EntityManager em;
....
@Asynchronous
public void permeabilityWeekCollect(String centerName,Branch branch, String weekscope){
...
// RUN FOR MORE THAN 10 MINUTES!!
em.persist(....);
em.flush();
em.clear();
}
}
According to the exception information, I think it is the closing state of permeabilitystatList which is the parent thread of permeabilityWeekCollectThread that make permeabilityWeekCollectThread lose context.
What should I do ??
Thank you very much!!!
