Subject Re: Artemis Core XA Example
Date Mon, 24 Oct 2016 22:40:53 GMT
- There is an “activemq-camel” component today, and since Artemis is
slated to become the next “ActiveMQ”, I was looking for functional
equivalents.  This is actually what started the whole question for me,
because I can do everything I need to do in core Artemis without
muddying the waters with JMS abtractions.  For example, the aliases
that get created for JMS destinations really confused me at first.


We are fixing the destinations on next release (1.6.0) 1.5.0 is bound
to be released this week.



Do we need a camel component within Artemis? if we do we can create
one.. but every I ask this question I get the same answer that we
don't need it given it's a bit different with Artemis.


if you found a real need we can certainly create it.

is simpler and I don’t drag in all the Spring dependencies.  The camel-sjms component does
some other things better IMO opinion as well - but it’s mostly because it’s simpler to
configure and easier to use IMO.

haven’t tried yet.
