[Design of JBoss jBPM] - Re: Services -changed from List to Set

by alex.guizar＠jboss.com

I think you are right, I played with that change a bit to examine its effects, but forgot to revert it when I committed. I'll do it now.

[Design of JBoss jBPM] - Services -changed from List to Set

by camunda

Hi Alex, in revision 4036 for jbpm 3.2.6 you changed the names of services in org.jbpm.svc.Services from an List to a collection. What's the reason for it? I think the list is a better choice, since closing the services then occur in the order like in XML, and for some services this can be relevant (e.g. closing the PersistenceService may cause problems if "later" services need something from the database during closing)... And efficiency isn't a big argument in this 5 services list I think... Not allowing duplicates could be introduced by a simple check in the addService... Or what do you think?

[Design of JBoss ESB] - Creating an FTP Provider and Listener for JBPM Callback Serv

by mallers

Hi There, Not sure i am in the correct place, but if not please let me know and I will post elsewhere. I am extremely new to JBoss and ESB in particular, however here is my scenario and problem. I currently have a JBpm (jPDL) process deployed on the server. I can goto the JBPM-CONSOLE, start a process and signal through the states. What I am trying to achieve, is to create an FTP Listener, which when an XML file is placed on the FTP server, will notify the Process to start. I see we can acheieve this using JBpmCallback. With this I will use the BpmProcessor to execute the StartProcessInstanceCommand. All communication is one-way, that is, once and XML file is placed on the FTP server, all that needs to happen is that the FTP Listener will notify the OSOD Process to execute and everything is handled by the process from there. There is no repsonse message (in keeping with loose coupling also as no dependancy exists). However, whne i configure the provider and listener in the jbpm.esc\META-INF/jboss-esb.xml, then and exception is thrown by JBoss: 12:25:10,437 INFO [NamingHelper] JNDI InitialContext properties:{} 12:25:10,656 ERROR [URLDeploymentScanner] Incomplete Deployment listing: --- MBeans waiting for other MBeans --- ObjectName: jboss.esb:deployment=jbpm.esb State: FAILED Reason: java.lang.RuntimeException: org.jboss.soa.esb.listeners.lifecycle.Mana gedLifecycleException: Unexpected exception while instantiating managed instance I Depend On: jboss.jca:service=DataSourceBinding,name=JbpmDS jboss.esb:service=JBPMDatabaseInitializer jboss.esb:deployment=jbossesb.esb --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.esb:deployment=jbpm.esb State: FAILED Reason: java.lang.RuntimeException: org.jboss.soa.esb.listeners.lifecycle.Mana gedLifecycleException: Unexpected exception while instantiating managed instance I Depend On: jboss.jca:service=DataSourceBinding,name=JbpmDS jboss.esb:service=JBPMDatabaseInitializer jboss.esb:deployment=jbossesb.esb I have The following Configuration in the jboss-esb.xml, if this is right or wrong i would really appreciate any inputs from anyone.

Sure. But can you do then a quick check on how much of other MC things break with this change? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213692#4213692 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4213692

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: rolled back messages delivered twice.

by timfox

Yes, this is what I have been going on about for the last couple of weeks. The session must be enlisted in the JTA tx *before* delivery occurs from the messaging provider, otherwise, to the provider the delivery was non transacted, since it didn't know about the tx at the time it delivered the message to JCA. So when you rollback it won't know about the delivery. This is what is covered in ML's tx book chapter 5 what I was talking about. You don't any kind of special message listener to do this correctly. You just need to: a) When the listener is first created and before it is added to the session, enlist the session for the first time. Then by the time onMessage is called you know the session is already enlisted, b) in *your* onMessage (JBMMessageHandler:onMessage) call the delegate onMessage, then delist and commit, then.... before returning from your onMessage, enlist the session again so by the time the next onMessage is called it's already enlisted, Note however, you shouldn't be using the tm.begin(), tm.commit() methods. These require commit or rollback to be called on the same thread as beging, which won't necessary work since subsequent invocations of onMessage can be called on different threads. You should therefore cache a reference to the JTA transaction object and call commit/ rollback directly on that since it does not require same thread to call it, and moreover JBM does not care about transaction-thread associations.: JTA spec, section 3.3.3 anonymous wrote : | | The Transaction.commit and Transaction.rollback methods allow the target | object to be comitted or rolled back. The calling thread is not required to have the same | transaction associated with the thread. | | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4213668#4213668 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4213668
