Support synchronous call to InVM ESB service under JTA transaction context
--------------------------------------------------------------------------
Key: JBESB-2631
URL:
https://jira.jboss.org/jira/browse/JBESB-2631
Project: JBoss ESB
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Affects Versions: 4.4 CP2
Reporter: Taro Yasuma
AS-IS)
Under JTA transaction context, assume you call ServiceInvoker#deliverSync() to call InVM
ESB service. Then the call is in dead-locked because the operation regarding InVM queue is
enlisted in the transaction.
As a workaround, you need to suspend the transaction before ServiceInvoker#deliverSync()
but it's inconvenient that you always do this workaround in application.
TO-BE)
1. To have a configuration option on ESB to avoid enlisting operation regarding InVM queue
in the transaction.
2. To have a configuration option on ESB to have no transaction boundaries between
operation of calling ESB service and operations of processing ActionPipeline. I.e. an
operation regarding ActionPipeline is enlisted in the same transaction of the operation of
calling ESB service.
If you enable #2, it will be much flexible for usecase that having fine grained services
but no transaction boundaries among them.
