SubReport - Threading causes problem in Hibernate

[raffimd]

Hi,

I have 2 subreports in a report.

Jasper Engine creates seperate threads for each subreport.

Because of the thread, I face some problem in Hibernate session. I am implementing the JRDatasource interface for the subreport and making many calls to spring service layer which calls the DB through Hibernate. Looks like the Hibernate session is gettign closed between the service layer calls.

Based on the analysis, I beleive that the spawned thread will cause this kind of Hibernate session issue.

 

Is there a way to control the spawning of threading and instruct the JasperEngine to run the subreports in the same thread of the main report?

 

Your help is really appreciated,

Thanks in Advance,

Raffi

You can switch to using Javaflow Continuations instead of threads for subreports. See this discussion for more details.
