The ActiveMQ Team is proud to announce the 3.1 release of ActiveMQ, an open source JMS message bus.

This release, available for download now, includes a large number of new features and improvements.

New features include:

• New Stomp support to make it easy to create cross language clients such as for Ruby or Perl etc. (Python, C and .Net coming soon)
• XPath based selectors and demand based publishing, making it easy to implement WS-Notification on top of ActiveMQ
• a pooling JMS ConnectionFactory for better support of the Spring JMSTemplate outside of a JCA container
• improved JNDI support to allow easy dynamic creation of Queues and Topics, to handle different connection settings and to reuse standard JNDI properties
• Increased support for the number of databases and JDBC drivers to include , Apache Derby, Oracle, Sybase, DB2, SQLServer, Postgresql, MySQL, Axion, HSQL
• improved authentication at the connection and destination level
• more flexible prefetch policy configurations for more control over queue dispatching and performance tuning
• improved support for priority message ordering
• cleaner servlet integration
• better XA integration to allow outbound producers to reuse inbound JMS sessions
• improved support for WebSphere and JBoss
• easier journal file size and checkpoint period configuration
• Jabber/XMPP transport
• various performance enhancements and bug fixes

ActiveMQ works well with Jencks, the Spring-based JCA container, for working with Message Driven POJOs inside any JVM as well as Lingo, the Spring Remoting implementation using JMS and JCA.

Enjoy!

Message bus? I thought it was a JMS provider? Or is it a case of staying in tune with the latest buzzwords perhaps? ;)

Nevertheless, great product, I have been using 3.0 since, well, since it was released I believe.

Its both a message bus and a JMS provider :)

Since ActiveMQ supports REST, Ajax & STOMP, you can argue its a message bus for non-Java folks or a JMS provider if you're a Java person :).

Thanks! Hopefully you'll find 3.1 is even better :)

man you guys sure move fast. congrats

I've tried ActiveMQ in a large scale messaging project and I'm not very impressed.
It is very poor at handling queues with a very large number of messages, specially if you need to restart the server. There is a bug ( http://jira.logicblaze.com/jira/browse/AMQ-324 ) which is a show stopper but that seems not to be fixed in this version.
In the end, I've switched to JbossMQ.

I'm very sorry to hear that Juliano. Any chance you could verify this issue is still valid for you in 3.1 and if so give us some information on how to produce it (as a comment on the JIRA issue), then we can get right on it and fix it. Certainly we've not heard of anyone else having that issue yet.

I would assume that a bit research would show that the term "message bus" predates the term "JMS". I know it's shocking, but there was life before Java ;-)

Are there any support forums available. I see none on the ActiveMq site. I see mailing lists , which I hate as they clutter your mail box.

We're in the process of setting a forum up to make it easier to keep track of the project and discuss issues.

Until then you could try using your NNTP news reader client or your RSS blog reader

http://dir.gmane.org/gmane.comp.java.activemq.user
http://dir.gmane.org/gmane.comp.java.activemq.devel

e.g. point your news reader at
nntp://news.gmane.org/gmane.comp.java.activemq.user

and you should be able to surf the mail list whenever you like without cluttering up your mail inbox.

Is there any supporting documentation for having a C client using Stomp? I found it for Ruby, but not for C. What does the ActiveMQ team recommend between using REST and Stomp? What is easier, and what is more performant?

We should have a Stomp client for C (libstomp) available soon.

What does the ActiveMQ team recommend between using REST and Stomp? What is easier, and what is more performant?

Stomp is typically better; though REST gets through firewalls so it depends on use case. Certainly connecting from C, Ruby, Perl, Python, PHP then for many use cases the Stomp version will be a little better - though it'll take a little while for the C, Python and PHP clients to show up. We welcome contributions! :)

Have you, or anyone, tried using the new Jabber support to utilize Google Talk (or another major Jabber network) as a transport ?

Congrats for the tireless campaign you are running all over TSS

Did you know that "Ruth Deis" is an anagram for "Rude Shit"?

"F*** u Charley"?

Seems like a common TSS thread:

1) Cool product has a new release.
2) A few comments and then someone says "it didn't work for me so I chose X" but did't log the issue.
3) Some random creates a new login to TSS and says confusing stuff we all assume came from a competitor but don't really care.
4) Someone else plugs their project coz they can.

Wait, where is (4), oh sorry thats me.

Thread closed, well done ActiveMQ gals and guys for the rapid development of an ever improving product.

I did actually log the issue. The JIRA link is in the original post.

I found memory leak in 3.0 and posted a bug report but NO ONE REPLY. Is that version response to all bug report!!!!

Unfortunately your bug report missed the cut of the 3.1 release; we like to freeze the code and system test heavily before doing a release to ensure things work great for our users.

We've seen your bug in JIRA and are working on it - we should have a new release with this fixed soon. Please be patient though; we have lots of users who report issues so it sometimes can take a while to get to certain issues - (and paying customers always come first :)

This is probably the silliest question on this thread, but I just have to ask:

ActiveMQ would be a perfect fit for my application, but I have to support users using applets with the VM that is built into Internet Explorer, which is Java 1.1.14.

Is there any way to talk to an ActiveMQ server from an applet running in Java 1.1?

Its a completely valid question :)

The JMS client is currently fairly dependent on Java 1.2 or later features like Java 2 collections etc.

However we've a number of alternatives to using our JMS client...

REST API (use HTTP POST/GET)
http://activemq.org/REST

Ajax (use JavaScript in your browser)
http://activemq.org/Ajax

Finally the Stomp project is interesting
http://stomp.codehaus.org/

ActiveMQ 3.1 has support for Stomp which already has a Ruby and Perl client with C and .Net clients on the way. Stomp is really easy to implement in any language or platform - so it'd be trivial to build a J2ME or small-applet client for Stomp to talk to ActiveMQ.

e.g. this is the entire Stomp ruby client :)
