[Design of EJB 3.0] - Re: jboss-ejb3-project

by ALRubinger

Some more thoughts: Naming I like "org.jboss.ejb3:jboss-ejb3" Remove the component artifacts from JBossAS If we provide a unified assembly for all EJB3 projects, then we may provide "jboss-ejb3.jar" as one artifact into AS. This provides the following benefits: 1) No more user confusion as to what version of the EJB3 project is in AS. A check into the manifest will simply say "1.0.0". 2) Removes the half-upgraded problem. Users won't be upgrading ejb3-core while neglecting to update ejb3-proxy or ejb3-common. 3) We can do away with the explicit dependencies upon the client classifier JARs: <version.org.jboss.ejb3>1.0.0</version.org.jboss.ejb3> < This one stays | <version.org.jboss.ejb3.common.client>1.0.0</version.org.jboss.ejb3.common.client> | <version.org.jboss.ejb3.core.client>1.0.0</version.org.jboss.ejb3.core.client> | <version.org.jboss.ejb3.proxy.client>1.0.0</version.org.jboss.ejb3.proxy.client> | <version.org.jboss.ejb3.proxy.clustered.client>1.0.0</version.org.jboss.ejb3.proxy.clustered.client> | <version.org.jboss.ejb3.security.client>1.0.0</version.org.jboss.ejb3.security.client> Refactoring Required In order to implement this, each component must have a dedicated namespace, ie. "org.jboss.ejb3.core" that doesn't conflict anywhere else. Otherwise there will be overwrites when we pack everything into one assembly. Take for instance in ejb3-core: http://anonsvn.jboss.org/repos/jbossas/projects/ejb3/trunk/core/src/main/...

This is not a design question. I will move this to the right forum, but in future such postings may simply be deleted.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Configure a queue to be ordering aware

by timfox

So.. I'm struggling a bit here to see where this thread is going. Let me try and piece it together. The way the messaging ordering is currently implemented in JBM is messages are ordered when they hit the server. This is the way it works/will work in JBM 2.0. Ordering messages by adding a time stamp on the *client* is not something I have heard of before, and I do not know of any other messaging systems that implement it that way. Using a timestamp from the client would have issues with clock synchronization on the client. The differences between timings on clients would probably far outweigh the time taken to send a message from client to server, thus rendering it pointless. For that reason, that option does not seem worth pursuing. There seems to be another issue on this thread regarding how this functionality is configured - whether the queue is configured as "ordered", or whether this is done on the connection factory. This second issue seems unrelated to whether we use timestamp from the client or order on the server. As I mentioned in my previous post I would prefer to configure on the connection factory since this is more consistent with JBM 2.0 and also does not restrict the entire queue to be "strictly" ordered only.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Configure a queue to be ordering aware

by gaohoward

Hi Tim, my point is how can you determine the ordering of message? I can think of two ways, one is determined by the senders, the sender can say message1 is the no1 and message2 is the no2, so JBM will obey this order. The other is determined by time, that is no matter who sends those messages, the order of them is determined by their time of arrival, but whose time should be used as the standard to judge the ordering?

by timfox

Like i say, ordering is always done on the server anyway. I'm not sure what you're point is here. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4206195#4206195 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4206195

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Configure a queue to be ordering aware

by gaohoward

sorry it's confusing. Calculate is not proper I think. Let me quote Taro's anonymous wrote : | Let me explain for your sure. Assume multiple producers, a queue and a consumer. Then, assume a scenario like: | | Time | t1 Producer1 ---> Message1 ---> Queue1 | t2 Producer2 ---> Message2 ---> Queue1 | t3 Producer1 ---> Message3 ---> Queue1 | t4 Producer2 ---> Message4 ---> Queue1 | | Where Time "tn" (n is integer) means the one when Queue1 receives a message from a producer | (the time relies on the clock on machine of Queue1). | | Then, Queue1 has Message1, Message2, Message3 and Message4 in order and the consumer consumes the messages in this order. | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4206193#4206193 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4206193

"gaohoward" wrote : I agree with your reason. There is one exception, if user wants the ordering of messages to be determined by the time they arrive at the target queue (the time is the machine time that hosting the queue), the ordering has to be calculated on the server. | I don't understand that, ordering is always calculated on the server. Perhaps you could explain the point in more detail....
