If you really need HAPartition at started state, I don't see how you can currently do that, but this can be easily fixed / hacked. :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4182042#4182042 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4182042

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Progressing On Ording Group Impl

by gaohoward

A reference count should be added in the register method for topic to work. (as topic involves multiple queues for one message) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4182016#4182016 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4182016

[Design of JBoss Build System] - Re: [JBASMP-2] Create an Undeploy Mojo

by ALRubinger

On some further thought, I think we're going to need the explicit ClassLoader no matter what. Which promotes it from "hack" to "necessary evil". Surefire does similar things to get the CP right when running tests. We simply can't define an explicit dependency to get jbossall-client on the client CP, so we've gotta define our own CL. I've applied one of Guillaume's patches which ensure there's no CCE due to the wrong CL being used.

[Design the new POJO MicroContainer] - Way to control when injection happens?

by scott.stark＠jboss.org

It turns out the clustering beans have a screwy relationship that is not working in general with the mc dependency injection: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4181999 The problem is that the HAPartitionCacheHandler relies on other beans to setup its properties, but does not express this relationship as a dependency because the other beans inject the HAPartitionCacheHandler so that they can call methods on it. In reality either these need to be rewritten, or a bean factory written that can wire these together correctly. The configuration that exists is: JBossCacheDistributedTreeManager injects HAPartitionCacheHandler.cache and depends on HAPartion and HAPartitionCacheHandler implicitly depends on HAPartition to initialize its cache. My question is can one delay injection of the HAPartitionCacheHandler.cache until the HAPartition bean is started?

[Design of Clustering on JBoss] - Re: HANamingService IllegalStateException: Must call setClus

by scott.stark＠jboss.org

Ok, so the dependencies just seem broken/unresolvable and I'm not sure why this would work in general. The problem I see is that: HAJNDI injects JBossCacheDistributedTreeManager.cache which is injected from HAPartitionCacheHandler.cache HAPartitionCacheHandler another bean, either DistributedState or HAPartition to initialize its cache by calling acquireCache(), but HAPartitionCacheHandler cannot depend on these because they depend on HAPartitionCacheHandler in order to call methods on it! What is happening right now is that the JBossCacheDistributedTreeManager.clusteredCache property is being injected from the HAPartitionCacheHandler bean cache property, but the cache property has not been set. The mc is assuming that since the HAPartitionCacheHandler is started, its properties are valid. This is not the case. Adding a dependency to the JBossCacheDistributedTreeManager on HAPartition is not changing when the clusteredCache property is set. The HAPartitionCacheHandler does not appear to be a valid bean in terms of dependency injection. I'm curious how this works before my reorg of deployments.

[Design of Clustering on JBoss] - Re: HANamingService IllegalStateException: Must call setClus

by scott.stark＠jboss.org

That's not it as that bean is really controlled by the DistributedStateImpl. Adding a naming dependency to it also does not solve the problem. Still trying to navigate the dependency graph to figure out what is not being initialized. Seems like there should be some error prior to this.

by scott.stark＠jboss.org

Whoops, wrong, its the clusteredCache which is being injected. I guess the HAPartitionCacheHandler has a need to depend on the Naming service as well?

Looking at the JBossCacheDistributedTreeManager that is throwing the exception, it is |  | <property name="distributedTreeManager"> | <bean class="org.jboss.ha.jndi.impl.jbc.JBossCacheDistributedTreeManager"> | <property name="clusteredCache"><inject bean="HAPartitionCacheHandler" property="cache"/></property> | </bean> | </property> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4181990#4181990 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4181990
