I have gotten Unicast clustering working with JGroups in UberMQ 2.7. I=20= have 2 servers setup in the cluster and they have successfully=20 connected together using port 7800 TCP unicast.=A0 =A0 However, when I publish a message using the "viewer" to one server it=20= get's sent to the cluster and is received by the second server which=20 then decides to send it back out to the cluster back to the original=20 server. This process continues back and forth and floods the network.=20 The message is getting continually duplicated even though the message=20 ID is the same. I have even tried running two servers on the same=20 machine to elminate clock time differences in case that was the problem=20= but it did not eliminate the issue.=A0 =A0 Any thoughts? Is there a config I need to setup? I do have loopback=20 set to true to eliminate the one server sending back to itself but in=20 the cluster it doesn't help.=A0 =A0 Regards,=A0 =A0 Peter= |

I was caught the following exception when I using UBERMQ: 2003-07-02 07:38:19,173 ERROR [STDERR] org.xml.sax.SAXException: FWK005 = parse may not be called while parsing. 2003-07-02 07:38:19,176 ERROR [STDERR] at = org.apache.xerces.parsers.DOMParser.parse(DOMParser.java:249) 2003-07-02 07:38:19,177 ERROR [STDERR] at = org.apache.xerces.jaxp.DocumentBuilderImpl.parse(DocumentBuilderImpl.java= :201) 2003-07-02 07:38:19,178 ERROR [STDERR] at = com.ssp.sspimserver.jabber.ubermq.JabberDatagramFactory.incoming(JabberDa= tagramFactory.java:98) 2003-07-02 07:38:19,179 ERROR [STDERR] at = com.ubermq.kernel.AbstractConnectionInfo.processData(AbstractConnectionIn= fo.java:368) 2003-07-02 07:38:19,181 ERROR [STDERR] at = com.ubermq.kernel.ConnectionInfo.readFrom(ConnectionInfo.java:93) 2003-07-02 07:38:19,182 ERROR [STDERR] at = com.ubermq.kernel.ReadWriteTransformThread.acceptPendingRequests(ReadWrit= eTransformThread.java:121) 2003-07-02 07:38:19,183 ERROR [STDERR] at = com.ubermq.kernel.ReadWriteTransformThread.run(ReadWriteTransformThread.j= ava:52).

Hello James, Thanks for your replying. Yes, I also have some problems with stop method in MessageServer class. According my words in Ubermq forum, The AcceptThread must be interrupted when MessageServer stop. Moreover, ReadWrite threads have interrupted but some connections are still alive. If you redeploy ubermq in Jboss application server, Binding Address Exception will happen( sun.nio.ch.Net.bind). If you are willing to help me, please show me more details to stop MessageServer. My program is going to support Windows NT/2000/XP and Linux platform. I am looking forward to hearing from you,James!

That's great. The documentation framework will help a ton. I actually just checked in a first pass at the reconnection piece - but it's far from done. It only detects connection loss when you try to write to the channel, so we should probably add a heartbeat facility or something like that so we can detect connection loss at a reasonable interval. Warren, I'll leave that to you. When you're ready to tackle the problem, let me know, and I'll steer you to the right place. It looks like no one wants to take message selectors, so I'll put that on my list. (Unless someone wants to help me out on that) James --- Warren Mira <wm...@cy...> wrote: > Guys, > > > Hello to everyone on the list. Im Warren and very glad to be on this > project.

Guys, Hello to everyone on the list. Im Warren and very glad to be on this project. I've been to java for sometime and also doing some JMS stuff ( especially on IBUS). James, I want to take on preparing the skeleton first for the documentation, ill commit it this coming weekend, ill primarily be using docbook. Then once im comfortable with the code, i want to help you out with item (2). For the future, im thinking of incorporating JMX within the project for management ( if everyone agree ) using mx4j (mx4j.sourceforge.net) for the implementation. Ok ciao for now... Warren |

Welcome to UberMQ! I'd like to take this opportunity to thank you guys for joining my project, and welcome everyone to the group. About the Project ================= UberMQ is a project that I've been working on since January of this year. Distributed messaging is a tremendously powerful metaphor, and behind the simplicity lies a bevy of tradeoffs. The design of UberMQ is ultimately very simple, but can be extended and modified in a variety of ways to solve a multitude of messaging problems. The entire product, as you know, is built on a one-to-many messaging model, and the client API is the topic half of the JMS specification. Most implementations get pub/sub horribly wrong - ubermq is not perfect, but is much better than most that I've seen. If you download the current 0.2 release and test out the sample code, you'll see that UberMQ is a fast, stable, world-class pub/sub messaging platforms that supports advanced features like clusering, durable subscribers (in a usable way), and overflow management. Getting to 1.0 ============== The 0.2 release that I built yesterday is very close to a production-quality messaging system built on one-to-many messaging. In order to get to a production quality 1.0 release, I think we need to focus on the following unimplemented features: 1. message selectors (the WHERE clauses you can attach to a subscriber). 2. reconnection (within clusters and without) That's it. Most features are actually fully implemented! Part and parcel of a 1.0 release, though, is documentation and other non-code deliverables: 1. User's guide (how to install, sample code walkthroughs of publishing and subscribing, how to use various features of the product). 2. Architectural overview (how its designed, how to customize the Message Server) 3. FAQ containing benchmarks and other reliability metrics 4. Sample code demonstrating various features. Timetable ========= The first thing I'd like everyone to do is to just send out a short introduction to the list, so we all know who's who and who is actively on the project. The next thing we should do is work out who'd like to work on what tasks of the above listed. If someone would like to just focus on writing sample code to try to break it (sending too fast, too many connections, etc.) that would be a big help too. Hopefully by tomorrow we'll be able to get people's names on the items above. The two code deliverables will need some architectural guidance from me to tell you where to put things, but they are not too difficult, so please volunteer if you're interested. I'd like to get a 1.0 release out the door before Sept is out. I think that's totally reasonable given the current stable state of the project. Also if you guys are in companies that use messaging, please get the name of our product out there. Once we have some successful installations to point to, we'll be well on our way. Conclusion ========== Again, welcome to the UberMQ project. I hope you have a good time working on this cool little distributed messaging product, and that we can turn this into a sustainable gig.
