I implemented it myself just to get things running locally with my copy. There may be
a more optimal way of implementing this but all I did was add a hook with the
SessionImpl and wrote the ObjectMessageImpl ad hoc so I could send messages of a
realistic size.

class ObjectMessageImpl extends MessageImpl implements ObjectMessage, Serializable {
private static final Logger log = Logger.getLogger(ObjectMessageImpl.class);
private Serializable _object;
public Serializable getObject() throws JMSException {
return _object;
}
public void setObject(Serializable object) throws JMSException {
_object = object;
}

For smaller messages (e.g. 1-2K), you should get at least 1000 msgs/sec.

sljms.xml is identical to default.xml from JGroup's conf directory. It is the standard multicast stack JGroups comes with. fc-fast.xml is a variation of the above, in that it enables bundling (UDP protocol waits until it has a buffer full of data or a timer expires, and then sends data on the wire), and compression, so it achieves a better performance for small messages. I guess Bela is the right person to ask for more details on protocols. This is how you install your own protocol: - write your protocol stack, say myprotocol.xml and place it in etc of the project - append to etc/jndi.properties: sljms.jndi.connectionFactory.MyConnectionFactory=myprotocol.xml After restarting your client, you can lookup MyConnectionFactory in JNDI and use it. Please note that all clients connecting to the same server must have the same stack configuration. anonymous wrote : Does the consumer or producer create the channel or whoever is started first?

If describing my data may help with optimizing the protocol stack... I'm primarily sending radar state information. Just for a rough estimate, I serialized the objects to a file (I know this isn't the most accurate way of getting the true size of the objects) but they range from 1.3kb - 2.0kb serialized. I was pretty happy with the rates I was sending out the text messages (I was able to get ~800 messages/second).

Ovidiuf, Thank you for the good documentation and the new version of the serverless JMS. I am anxious to work with this new code base this week. If I may inquire, I'd like to know if you would be willing to receive code contributions? We can talk about this offline if that's appropriate? It seems that you and Bela are the only ones working on this and my development team may be interested in helping out and expediting some features. We already developed our own pluggable protocol (Unicast, Multicast, etc...) with a free CORBA implementation. However, J2EE seems to have many features we'd like to exploit and it seems like a superior option if we can get some of the JMS features implemented that are show stoppers for our project. So some of the things we'd like to have is the JNDI linked into JBoss NS (we'd like to have the ability to federate name services), getting the persistence and fault tolerance, message selectors (a must have for us), and possibly others I'm not thinking of right now - I may come across others as I prototype some things this week. We'd like to get this up to a stable 1.0 release in the near future if that's possible and I'd like to talk more about it if you're interested?

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Multicast JMS
A version that contains everything you need to experiment with your relaying solution is ready to be released. I don't want to call it 0.2. Not that the name matters, anyway, but 0.2 was supposed to include persistent delivery, and I am still working on that. I will post the URL on the forum later today. Or early tomorrow. This is how you configure it: Let's assume you use the machine A and B on the same LAN and they can see each other by multicast, and a machine C that is on a remote site. If your LAN is protected by a firewall, you must be able to open a port in the firewall, in this case 12003. If you use NAT, forward the port to A. 1. On A, start the JGroups' GossipRouter (you can find a jgroups.jar in the bundle, or you can compile it independently http://www.jgroups.org): java -cp lib/jgroups-core-2.2.1.jar:lib/log4j.jar org.jgroups.stack.GossipRouter -port 12003 2. On A, have your bridging client look up the RouterConnectionFactory. You configure it by modifying etc/router.xml. The only thing to change there is router_host, which is is the public IP address of A. The same client has to look up ConnectionFactory, which provides multicast connections. Take a look at etc/jndi.properties, you'll find it self explanatory. 3. On C, look up RouterConnectionFactory. It has to be similarily configured. Now A and C clients can exchange messages. 4. On B, look up ConnectionFactory. Now A and B clients can exchange messages. 5 If your bridging client on A switches back and forth messages from a connection to the other, B and C can exchange messages. This is just a proof of concept. There is no reason to have an application-level bridging client. The bridging between multicast and unicast will be transparently handled by JGroups. In a future version, of course. And by the way, there's no need to write even a line of code to test what I've just explained above. Take a look at the interactive client provided with the bundle. There is a short description of how it works in the documentation. It can create JMS objects (connections, sessions, producers and consumers) at command line so you can mix and match and build your prototype. a href=http://www.jboss.org/index.html?module=bbop=viewtopicp=3826545#3826545;View the original post/a a href=http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3826545Reply to the post/a --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Multicast JMS
So let me ask you this... Is it currently possible to send that JMS through a firewall? Can I send it multicast and rebroadcast unicast and vice versa or is that impossible in the 0.2? Would there be a significant development effort to do this? Here's what I'm thinking and perhaps what I could do is this: Configure a producer to a topic using 1 channel via mulicast. Have a consumer connect and retrieve that data via the same protocol stack configuration. Have it then somehow send data (forward it) to another topic that would create another channel with a different protocol stack (unicast or firewall) and send it that way? Would that at least be possible to do? Can I pass in another jgroups xml file and overwrite the protocol stack...I don't have issues using another channel to do this. I just want to make sure it's possible. a href=http://www.jboss.org/index.html?module=bbop=viewtopicp=3825287#3825287;View the original post/a a href=http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3825287Reply to the post/a --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

[JBoss-user] [Messaging, JMS JBossMQ] - Re: Multicast JMS
Your solution is in principle correct, and, oddly enough, almost possible to implement with the current alpha release. Basically, you'll have to write a bridge client, that creates two connections to two different serverless JMS providers. The first one runs over the multicast domain and the other one has a JGroups stack that uses a router or direct TCP. You'll have to write the bridging code, based on the topic name, etc. There is a small problem with the way the connection gets its configuration information, right now is kind of hardcoded, but this is easy to fix. I'll have to change the JNDI implementation for that. The good solution to the problem is to add bridging code to JGroup itself. This way, you won't have to send messages up and down the stack just to take a routing decision at application level. We have plans to add that, as well. If everything works out OK, a version that supports the solution you described should be available some time next week. a href=http://www.jboss.org/index.html?module=bbop=viewtopicp=3825310#3825310;View the original post/a a href=http://www.jboss.org/index.html?module=bbop=postingmode=replyp=3825310Reply to the post/a --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
