[Messaging, JMS & JBossMQ] - Re: Sequential processing of messages with the same Key

by adrian＠jboss.org

Ok, since I haven't answered this question this month, I'll answer it again, but only in the short version (well actually with the full caveats in case somebody else figures out where the search engine is - its in the top right by the way :-). What you are asking for is the default behaviour, but you need to think about it. Messages are delivered in the order they are sent. But with the following caveats. 1) They all have the same priority 2) The receiver is not filtering messages (i.e. ignoring some messages) 3) There is only one sender (senders can race with each other when sending) 4) There is only one receiver on the queue (messages could go to different receivers if there are multiple) - not relevant for topics 5) A message is not NACKed (negatively acknowledged) - if a message is Nacked and redelivered then all bets are off 6) You don't use scheduled delivery So the answer to your question is (partially) to create topic subscriptions with a selector for each customer, but be prepared for redelivery not respecting the order. MessageListener instances (client side) can be attached to multiple subscriptions. And JBoss supports multiple subscriptions for an MDB (not in the spec) by configurating multiple invoker-proxy-(bindings) in jboss.xml How you avoid the senders racing with each other is something you'll have to resolve yourself (if that is relevant), probably with some kind of shared lock on who can send messages.

The import.sql file on the classpath is automatically executed when you have | <property name="hibernate.hbm2ddl.auto" value="create-drop"/> | in persistence.xml View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067563#4067563 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4067563

[JBoss Seam] - Re: How bad is unused conversations?

by emsa

Well you could use conversationList but how do you know what conversations are in use? The user could use several windows so many conversation could be active. The (only) way do solve this (if it really needs solving) is to extend s:link (or similar) with a new propagation, say, endAndBegin and one extra parameter, conversationIdToEnd. The server (probably SeamPhaseListener) will do exactly the same as with begin plus that it will set the timeout to 0 or promptly end the Conversation with the conversationIdToEnd.

[JBoss Seam] - Is org.jboss.logging.Logger in JBoss 4.2.1 compatible with S

by tonylmai

Hello all, I am running into weird logger incompatible version after upgrading my JBoss AS to JBoss 4.2.1GA (from 4.0.5GA). I am still using Seam 1.2.1GA. No change in my code. Yet my client is now complaining that it could not perform a Context.lookup(). It threw an exception at: anonymous wrote : java.lang.NoSuchFieldError: TRACE | at org.jboss.logging.Log4jLoggerPlugin.isTraceEnabled(Log4jLoggerPlugin.java:85) | at org.jboss.logging.Logger.isTraceEnabled(Logger.java:122) | at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:620) So somewhere in the server/client, a wrong version of Logger is being used and I don't know which component is loading this Logger in the first place. Has anyone here run into this problem or know how to fix this. I would appreciate a comment.

@SmokingAPipe: Thanks, I do not care for multiple different searches in different tabs yet, I just want the DataModel available on the page that I redirect to.

[Messaging, JMS & JBossMQ] - Re: Unexpected redelivery of messages

by adrian＠jboss.org

You probably also want to configure this: http://jira.jboss.com/jira/browse/JBAS-1341 + related links since it isn't enabled by default (it is still considered "experimental" - i.e. not enough users have tried it out yet - no bugs have been reported with it, yet.... :-).
