[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Some thoughts on large messages and message chunking

by clebert.suconic＠jboss.com

I'm writing LargeMessages on File on the ServerSide, so the Server's memory won't be all used up. I'm currently working on add this functionality on the PersistenceManager, so when we implement a DBPersistentManager, we could have LargeMessages stored on the DB. I have a question regarding NullPersistence. Should we just keep the message in memory when NullPersistence, or should we use the File also? What would make more sense?

[Design of JBoss jBPM] - Re: Process/task search based on variables

by kukeltje

this actor id stuff can be used *now*, just implement it that way 'businesskey's ' on task is under discussion, so do not count on it yet, btw, the target for an alpa1 release is 1 nov, so a full GA release is still way off View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179844#4179844 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4179844

[Design of JBoss Transaction Services] - Re: TransactionManager and AS' ServiceBindingManager

by wolfc

All in all this thing should never communicate with SBM in the first place. It's not some network service which AS provides. It's a hack around a JVM limitation. There are no real configuration options, because the option should actually be called: process id. So running two JBoss AS instances on one machine with the same 'process id' results in an error. I think transaction-jboss-beans.xml should just be configured with a '0' setting => go figure out your own process id. The fact that this must happen via a localhost socket hack is an implementation detail. (Note that this not invalidate JBTM-406.) If anyone would configure one instance to use another interface it would screw things up badly. If anyone would preconfigure a port and do two micro startups, it would screw up as well. So no configuration is the best way out.

[Design the new POJO MicroContainer] - Re: Federated resource visitor

And since I'm already so 'close' to FooBar class (doing @Name inspection), why don't I also read overriden xml part (if it exists)? Instead of remembering which are Seam components, and then doing CL:findResource lookup for possible override. Eventually implementing some custom ResourceContext (RC) to generically read that found resource. Where I could simply use existing RC with all fancy hooks - getBytes, getInputStream, ... And afaik they also have a need for other suffix / regexp matching resources, e.g. -page.xml (or something similar). This would allow to place resources anywhere in classpath, making it possible for users to group some stuff. But in general, thinking about the federated stuff, I'm surprised it didn't pop-up before. e.g. doing @annotation read + some other class inspection on the same Module, while still keeping things separated by what they do, not what they match View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179833#4179833 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4179833

My question was, why do you need to do any complex visiting/caching when the plain old classloading api does the job required. i.e. You know the resource path(s) up front so a lookup is more efficient It's not like classes which has no ClassLoader.getClassNames() and even it did, you want to cache/index the annotations once anyway.

Email is lagging somewhat, so the JIRA notification has not shown up yet. Glad you mentioned it or I would have wound up creating a duplicate issue.

lol Did you look, or did you notice that I created https://jira.jboss.org/jira/browse/JBTM-406 at the time I posted ;-) ?

On the page of first user sees all requests he requested and he can cancel some of them -> key should be friend. User2 sees all the requests he can accept/reject -> key should be friend2 They can't have the same key. So solution for this is to have business key in TaskInstance not in ProcessInstance. And this will be the solution for first case as well and I can left out ssn form business object:) I think that it is better to refence object form process and not vice versa. Now we use this solution and I call it business object as "task owner" and the id of business task is stored in task variable. It is not the same as assigning task to user because authorization is there as well so it is assigning task to combination of showed business object and logged user. What do you think about this? Actor-id's can be any strings, so also a combination of businessobject and userid.
