Re: Artemis Core XA Example
What's the reason behind wanting to avoid using the JMS layer in favor of the proprietary Artemis core API? I've not done anything with Artemis, so this is very much a question from a place of ignorance, but Quinn's statement sounded a lot like "I only want to use Hibernate-proprietary APIs, none of those pesky JPA-standard ones that might let me interoperate or swap underlying technologies later," and I'm curious about the logic that led to the statement...

ActiveMQ network of brokers messages are not balanced
I am using *ActiveMQ 5.13.4* and I have set up a *network-of-brokers* with
two brokers *A* and *B* that are connected via a *networkConnector*. Each
broker has a consumer connected to it (*A' *and *B'*). *A'* and *B'* consume
messages from the same *distributed queue* (e.g. `requests-queue`). Each
consumer is a java application, represented by a Spring
*DefaultJmsListenerContainerFactory* having the setting *concurrency: 5-10*.
Basically, each consumer has max 10 threads that can consume simultaneously
messages from the queue.
In broker configuration (`activemq.xml`) I have set the prefetch size to 1,
assuming that there are not many messages and they need a lot of processing
time.
```
```
The *desired behavior* is when I send 100 messages to `A` it starts
processing 10 messages simultaneously (one for each consumer thread) and
forwards another 10 to `B`. When `B` finishes processing the first 10
messages, it would get an extra 10. This would continue until all the
messages are processed.
The *actual behavior* is that when I send 100 messages to `A`, it sends 10
messages, one per each thread, to the local consumer `A'` and forwards the
remaining 90 to `B'`. The consumers on `A'` finish processing the messages
and they wait while 90 messages get processed on broker `B` by its
consumers.
*Question:* How can I configure the network in order to balance messages
based on consumer availability?
The full `activemq.xml` configuration for one of the brokers is the
following. The other one has the same configuration only a different name
and IP in the networkConnector.

Re: HornetQ client connect to Artemis server
I am all set. My problem was when we embedded the Artemis server, we missed the jar arttemis-hornetq-protocol-1.x.0.jar. Thanks. -- View this message in context: http://activemq.2283324.n4.nabble.com/HornetQ-client-connect-to-Artemis-server-tp4717861p4718084.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
ApacheCon is now less than a month away!
Dear Apache Enthusiast, ApacheCon Sevilla is now less than a month out, and we need your help getting the word out. Please tell your colleagues, your friends, and members of related technical communities, about this event. Rates go up November 3rd, so register today! ApacheCon, and Apache Big Data, are the official gatherings of the Apache Software Foundation, and one of the best places in the world to meet other members of your project community, gain deeper knowledge about your favorite Apache projects, learn about the ASF. Your project doesn't live in a vacuum - it's part of a larger family of projects that have a shared set of values, as well as a shared governance model. And many of our project have an overlap in developers, in communities, and in subject matter, making ApacheCon a great place for cross-pollination of ideas and of communities. Some highlights of these events will be: * Many of our board members and project chairs will be present * The lightning talks are a great place to hear, and give, short presentations about what you and other members of the community are working on * The key signing gets you linked into the web of trust, and better able to verify our software releases * Evening receptions and parties where you can meet community members in a less formal setting * The State of the Feather, where you can learn what the ASF has done in the last year, and what's coming next year * BarCampApache, an informal unconference-style event, is another venue for discussing your projects at the ASF We have a great schedule lined up, covering the wide range of ASF projects, including: * CI and CD at Scale: Scaling Jenkins with Docker and Apache Mesos - Carlos Sanchez * Inner sourcing 101 - Jim Jagielski * Java Memory Leaks in Modular Environments - Mark Thomas ApacheCon/Apache Big Data will be held in Sevilla, Spain, at the Melia Sevilla, November 14th through 18th. You can find out more at http://apachecon.com/ Other ways to stay up to date with ApacheCon are: * Follow us on Twitter at @apachecon * Join us on IRC, at #apachecon on the Freenode IRC network * Join the apachecon-discuss mailing list by sending email to apachecon-discuss-subscr...@apache.org * Or contact me directly at rbo...@apache.org with questions, comments, or to volunteer to help See you in Sevilla! -- Rich Bowen: VP, Conferences rbo...@apache.org http://apachecon.com/ @apachecon
