Transactional Client in Camel

[yogu13 <yo...@gmail.com>]

Hi,

Wanted some clarity on the usage of Transactional Client

In situation like below

<route>
 <from uri="jms:queue:inputQueue"/>
 <transacted ref="required"/>
 <log message="Received Message"/>
 <to uri="direct:postResponse"/>
</route>

<route>
<from uri="direct:postResponse"/>
<log message="Processing"/>
<to uri="jms:queue:outputQueue"/>
</route>

Considering the above route does the transaction span from the getting the
message from the inputQueue till the message is posted on to outputQueue ?
and would any issue/exception raised during processing trigger rollback of
message to the inputqueue ?

Please let me know incase any further details are required

Regards,
-Yogesh

Thank you David,

One last question on this regard..since transactional client signifies start
of the transaction, does that mean configuration properties like
transact=true and transactionManager on the jms endpoint wouldn't kick start
a transaction as soon as a message arrives and instead it is only started
once transactional client tag is encountered in route ?

It commit's as the route is complete.
Transcational client is nothing more than demarcating start of the
transaction.
It lives on top of Spring PlatformTransactionManager:
http://camel.apache.org/transactional-client.html
An endpoint midway in the route that does not support transactions is no
different than calling a non-transactionaware pojo from a transactional
service in a traditional spring way.

Hello,

Thank you for answering ..please help me understand what happens if within
the route if there is a endpoint which doesn't support transactions? in this
case, does the transaction started gets committed as soon as it encounters
such an endpoint ? or only gets committed at the end of the route ?

Thanks in advance,

Regards,
-Yogesh

You can span routes if it happens synchronously (same thread) that is using
direct:endpoint between them

any one used transactions before with jms ? did that span across routes or
was limited to the route in which it was started ?
