[Design of Clustering on JBoss] - Re: Default JGroups Configs

by bstansberry＠jboss.com

Yep, jaikiran's correct. Those properties are very often not set and the default comes from the system property substitution logic. Can you think of anything you might have done that would interfere with that? Somehow setting the property to "" ???

[Design the new POJO MicroContainer] - Re: DESCRIBE phase - Dependency builders for MC Beans

"jaikiran" wrote : While i am trying these things out i'll also check, in the current AS, how many beans need this AOPDependencyBuilder. Just want to reduce the number of MC clients that need to add this additional configuration to override the behaviour. | How would you know? The idea of the AOPDependencyBuilder is to make a bean depend upon an aspect. Where only AOP knows that it applies by the looking at its configuration (which is user configurable). Sure there's not much configured by default except the @JMX aspect but that doesn't mean that users won't configure aspects (including for our beans). Its the very nature of aspects being cross cutting that makes the AOPDependencyBuilder required in the first place. i.e. you have to ask aop whether there are any aspects that need to be applied to this pojo and therefore we need to wait for that aspect to be deployed (which might in turn depend upon other things) before deploying the pojo. Otherwise you could just configure the dependency directly on the bean. Just removing the AOPDependencyBuilder might make it faster. But all it will mean is that it will fail later when AOP tries to apply an aspect that is not fully deployed yet. If you really want to exclude the AOPDependencyBuilder processing from a bean then you should really use one of AOP's existing mechanisms like exclude "org.jboss.ejb3.*" from having aspects applied to it (that can be configured on the AspectManager). That way AOP should be able to "short circuit" the aspect dependency checking for those pojos using the same "filters". You'd be better off speaking to Kabir about how to optimise/avoid the AOP checking for what you want than getting Ales to hack things into the MC that are fundamentally wrong.

[Design of JBoss jBPM] - names for personal task list and takable task list

by tom.baeyens＠jboss.com

hi, i want decide on the names for the 2 specific task lists in the console: 1) the list of tasks directly assigned to the authenticated user. aka personal task list, aka assigned task list 2) the list of tasks that the currently authenticated user can take. aka group task list, aka takable task list whatever name we choose, we must use the same in the api, impl as in the console. suggestions ?

by kabir.khan＠jboss.com

Yes, I think AOPConstructorJoinPoint without the AOPDependencyBuilder is pointless, and vice versa. It would cause problems if the aspects actually have dependencies | <aop:aspect xmlns:aop="urn:jboss:aop-beans:1.0" | name="TxAdvice" | class="org.acme.aspects.TxAspect" | <property name="txManager"><inject bean="TxManager"/></property> | </aop:aspect> | <aop:bind xmlns:aop="urn:jboss:aop-beans:1.0" | pointcut="execution(* *->@org.acme.Tx(..))">; | <advice aspect="TxAdvice" name="invoke"/> | </aop:bind> | but not really of they don't | <aop:aspect xmlns:aop="urn:jboss:aop-beans:1.0" | name="Blah" | class="org.acme.aspects.Blah" | </aop:aspect> | <aop:bind xmlns:aop="urn:jboss:aop-beans:1.0" | pointcut="execution(* *->@org.acme.Blah(..))">; | <advice aspect="Blah" name="invoke"/> | </aop:bind> | But if you are sure you don't want aop for a set of beans, then both should be turned off View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4230478#4230478 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4230478

I'm just adding tests for this and I stumbled upon a hurdle. :-) Having non-AOP DB doesn't mean we'll use non-AOP ConstructorJoinPoint. And this could lead to weird behavior; aspect being applied w/o dependencies being properly resolved. I'll check how I can tie the two things together.
