[Design of JBoss ESB] - Re: sequece jms gateway processing

by kurt.stam＠jboss.com

This is a pretty standard pattern and is called the 'sequencer pattern'. We have been implementing some of these patterns, but we don't have this one yet. The 'Enterprise Integration Patterns' book has a pretty nice description of it. Your suggested solution makes sense to me. Maybe you can contribute the service (SequencerAction) back to us :). --Kurt View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128386#4128386 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4128386

[Design of JBoss ESB] - sequece jms gateway processing

by acure

I have service A with 3 listeners a_listener1 maxthread=10 b_listener2 maxthread=1 c_listener3 maxthread=1 gateway="true" I will be sure that all request from gateway will be processed in sequence - first in first out. That is guaranted only when messages from gateway are send to b_listener2 with 1 thread. I need to have a_listener1 with more than one threads for calls from other services. In org.jboss.soa.esb.listeners.gateway.JmsGatewayListener i see that gateway uses all eprs :/. How can i set destination listener for gateway? if only it is possible... it will be good to have some solution for sequence processing from gateway. Some solution will be to add property to gateway listener e.g. target-listener which will define destination input listener for this gateway. but it's only suggestion. how do you see this problem ?

[Design of POJO Server] - Re: Can you create a MetaValue object without an actual valu

by adrian＠jboss.org

A MetaValue without a value is just a MetaType. I don't see why you need to create a MetaValue without a value, you just need to have access to the MetaType in your template. This is already the case for ManagedPropertys: | /** | * Get the type | * | * @return the type | */ | MetaType getMetaType(); // Never null | | /** | * Get the value | * | * @return the value | */ | Object getValue(); // Could be null | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128375#4128375 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4128375

[Design of JBoss jBPM] - Re: identity management

by kukeltje

wrong forum (belongs in the userforum) but the answer is: no there that is not possible Personally I'd think it belongs in the identity component View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128353#4128353 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4128353

We don't have just ant ant build. We have a customized ant build that tries to do some dependency management things mvn does. There was no good reason to try to fix this when other tools exist.

[Design of JBoss Build System] - Re: JBossAS CR1 build plan

by richard.opalka＠jboss.com

Sorry for this out-of-topic question but: Why there is a plan to switch from ANT to MVN? What are the pros/cons that drive this move? Is there an analysis evaluating it? I'm asking because AFAIK MVN based build will be slower, more error prone and its auto-magic handling of dependencies will cause us more problems than benefits it will bring us.

[Design of JBoss jBPM] - identity management

by bud85

hello, I am looking for an information about identity management. Is it possible to automatiqualy assign a task to an second user if the first one assigned with the task is not here(holidays, illness, meeting,...)? does it have to be declarated in the identity management component or in the process definition? Thanks a lot! jean View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128292#4128292 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4128292

In fact, I've created a separate test class called PreferredMasterElectionPolicyUnitTestCase that contains these tests for two reasons: 1.- They're standalone unit tests, no need to have AS running for them. 2.- They're PreferredMasterElectionPolicy specific in the sense that I test any type of input into setPreferredMaster() and see whether it choses the given master after calling elect(). If the given master is invalid for any reason, it should delegate on the simple election policy.

Re 1) Each of the different preferred master definitions is in a different test method, i.e. testIpPort, testHostPort, testOnlyPort, testNonNumericPort, testUnknownHost... that should be enough, shouldn't it? Re 2) I think I have that one covered, i.e. public void testUnknownHost() throws Exception | { | policy.setPreferredMaster("onceuponatimeinalandfarfaraway:1199"); | /* invalid preferred master definiton, so 1st candidate in the list | * should be chosen */ | assertEquals(candidates.get(0), policy.elect()); | } | Btw, while running the the clustered tests for ha singleton election, I have spotted the following WARN message when the last node in the cluster stops and this is the node where the ha singleton was running: | 2008-02-10 22:50:57,675 WARN [org.jboss.ha.singleton.HASingletonController] Stopping failed test:service=HASingletonController_1 | java.lang.IllegalStateException: list of cluster node candidates where to run the singleton cannot be null | at org.jboss.ha.singleton.HASingletonElectionPolicyBase.elect(HASingletonElectionPolicyBase.java:103) | at org.jboss.ha.singleton.HASingletonSupport.partitionTopologyChanged(HASingletonSupport.java:169) | at org.jboss.ha.jmx.HAServiceMBeanSupport$1.replicantsChanged(HAServiceMBeanSupport.java:244) | I'm gonna change HASingletonElectionPolicyBase so that it doesn't throw a ISE when the list of candidates, but instead logs a debug message.
