Re: putting 2 components (WS=>XSLT) into a transaction

[Guillaume Nodet]

I think that in your scenario, no transaction is started.
You should configure the jms consumer to use JCA instead
of plain jms.  This would ensure a transaction is started by the
jms component, the message consumption would be enlisted
in the transaction, and the transaction would be sent with the
exchange to the next step...

Hi,

I want to put in a "transaction" the following execution:
WS (queue reader)=>XSLT (transformation)

so that if the second compoment fails (e.g. in case of a bad XSLT
transformation), the JMS message is not consumed and stays in the queue.

I have read SEDA flows support: Synchronous+Transactional
<http://incubator.apache.org/servicemix/transactions.html>

My "conf" repository is like the original/distrib one.

My ServiceMix pipeline is quite simple and defined as below.

I am testing with a bad XSLT transformation. Result = the JMS message is
consumed if the second stage fails.

Does someone have an idea ?

Many thanks.

Dominique


NB : My ServiceMix pipeline is like :

<bean id="connectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory">
  <property name="brokerURL" value="${activemq.url}" />
</bean>
