[Design of Messaging on JBoss (Messaging/JBoss)] - Re: discarding consumer messages.

by timfox

It's easier and more efficient to reject messages at the server and not the client. What need is a header in a message HDR_SOLO_MESSAGE (or whatever). I sent a stock price to the queue and set the HDR_SOLO_MESSAGE to the stock ticker symbol e.g. RHT. When the queue receives the message, it checks to see if HDR_SOLO_MESSAGE is present, if so, it looks in its local map to see if there is already a message in the queue with the same value of HDR_SOLO_MESSAGE. If not, then it just adds the message as normal to the queue as normal. If so, then it removes the older reference with that header value before adding it. In such a way there will only be the latest message for each stock ticker value in the queue at any time. I.e. only the latets price would be available. This can be done by subclassing QueueIpl and adding the map and extra check on routing.

[Design of JBossCache] - Re: JBoss Cache Options API

by manik.surtani＠jboss.com

True. And if they are passed in explicitly via varargs, we get over all of the thread local issues. Not too sure about a separate option subclass for each option though - might be a bit heavy. Perhaps options could be an enum, given that each option is just a boolean switch (with the exception of lockAcquisitionTimeout and syncReplTimeout, that is). As for lockAcquisitionTimeout and syncReplTimeout, AFAIK lockAcquisitionTimeout is only used to zero the acquisition timeout for putForExternalRead(), so it could be replaced with a boolean zeroLockAcquisutionTimeout. I don't see where syncReplTimeout is used, maybe it is unnecessary? So, Options may now look like: | public enum Options { | FAIL_SILENTLY, CACHE_MODE_LOCAL, SUPPRESS_LOCKING, FORCE_WRITE_LOCK, | SKIP_CACHE_STATUS_CHECK, FORCE_ASYNC, FORCE_SYNC, | // ... etc ... | } | And the CacheInvocationDelegate creates an EnumSet from these and adds this EnumSet to the invocation context before passing up the chain.

[Design of JBoss jBPM] - Re: jBPM for game development?..

by kukeltje

it's not impossible, not at all... I was just struck by the way Tom commented. If it is step by step and you want persistence of each step, you can use jPDL, if it is step-by-step and you don't want persistence, you can use pageflow. There is a hangman (the game) example in the seam code that uses pageflow View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205810#4205810 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4205810

[Design of Messaging on JBoss (Messaging/JBoss)] - discarding consumer messages.

by ataylor

This is regarding https://jira.jboss.org/jira/browse/JBMESSAGING-1214. If you consider the example where a consumer is receiving messages regarding a stock price then these messages are transitory. The consumer is only really interested in the newest messages. If the consumer is slow then these messages could build up and the information being received out of date. It should be possible to set the max number of messages to keep. My first thought is to do this in the server consumer. during the handle method if maxNumberOfMessages is set we check how many messages the queue has and if greater we we pre ack the message without delivering and return handled. The one thing I'm not sure of is how this would work with filters since only a subset of the queue may be destined for this consumer. thoughts?

to bad we are not leveraging seam or other existing jboss projectds.... so much duplicate work now..... it's a pity (and in the end a pita to maintain) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205808#4205808 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4205808

This forum us for people working on the core of jbpm, not users of jbpm. We have the user forum for that http://www.jboss.com/index.html?module=bb&op=viewforum&f=217 which you know exists since you posted in it earlier: http://www.jboss.com/?module=bb&op=viewtopic&t=140747 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4205805#4205805 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4205805
