I cannot understand why getProcessInstance() has to return Execution, it should return process instance by its meaning. And ProcessInstance is extends from Execution, it has all method declarations of Execution. Return ProcessInstance is more clearly, and won't effect any Backward compatibility. Do you have any idea about this? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545077#545077] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss AS Documentation] - Problem with JBoss Classloading.

by Sandesh Satam

Sandesh Satam [http://community.jboss.org/people/sandesh.satam] created the discussion "Problem with JBoss Classloading." To view the discussion, visit: http://community.jboss.org/message/545065#545065 -------------------------------------------------------------- All, I am struggling with class loading configuration for my web application. Following is the current configuration in jboss-classloading.xml (JBoss 5.1.0): <classloading xmlns="urn:jboss:classloading:1.0" name="mv-web.war" domain="DefaultDomain" top-level-classloader="true" export-all="NON_EMPTY" import-all="true"> </classloading> I had to define the classloading configurations definitions to resolve ClassNotFoundException thrown by Quartz while loading the jobs from the data store(Oracle). My web application is based on Adobe Flex and clustered LiveCycle Data services(LCDs). LCDs uses jgroups for clustering. With the custom classloading definitions, the LCDs clustering is not able to find its peer due to conflict in the jgroups.jar file version with the one used by JBoss. Jgroups version used by JBoss is 2.6.10.GA while the one used by LCDs is 2.7.0.GA. I guess the problem is due to the import-all being set to true. I have tried different configuration as suggested in http://java.dzone.com/articles/jboss-microcontainer-classloading http://java.dzone.com/articles/jboss-microcontainer-classloading. I want to exclude any jars contained in my web application for LCDs from the custom classloading and also only use the jars provided by JBoss is they are not present in my WEB-INF/lib directory. Please suggest. Thanks, Sandesh -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545065#545065] Start a new discussion in JBoss AS Documentation at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Yes, The checkActive() method should check subProcessInstance's state. And I think returning ProcessInstance may be better.

Re: [jboss-user] [EJB 3.0] - Possible Deadlock Jboss 4.2.3

Using JBoss Profiler ( http://www.jboss.org/jbossprofiler http://www.jboss.org/jbossprofiler) we determined that a bottleneck caused a backlog and since we use Semaphores to enable FIFO processing of messages, the locked threads built up causing the appearance of a deadlock. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545044#545044] Start a new discussion in EJB 3.0 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[EJB 3.0 Development] - enabling org.jboss.ejb3 tracing causes ajuna error : The transaction is not active!

by Daniel Cullender

Daniel Cullender [http://community.jboss.org/people/cullendw] created the discussion "enabling org.jboss.ejb3 tracing causes ajuna error : The transaction is not active!" To view the discussion, visit: http://community.jboss.org/message/545043#545043 -------------------------------------------------------------- Hi, We are using jboss 4.2.3 and we noticed a really bizarre bug. When we enable tracing for org.jboss.ejb3 in the jboss-log4j.xml file with the following entry: <category name="org.jboss.ejb3"> <priority value="TRACE"/> </category> We start getting this arjuna exception every time we put a message on our topic. It seems like the transaction changes mid transaction, causing an inconsistent state which arjuna does not like : 12:10:06,247 WARN [MessageInflowLocalProxy] Current transaction TransactionImple < ac, BasicAction: -53ec9f29:d858:4bfe44ad:ca2 status: ActionStatus.RUNNING > is not the expected transaction. 12:10:06,247 WARN [arjLoggerI18N] [com.arjuna.ats.arjuna.coordinator.BasicAction_34] - End called on already committed atomic action -53ec9f29:d858:4bfe44ad:434 12:10:06,247 ERROR [JmsServerSession] Unexpected error delivering message org.jboss.mq.SpyObjectMessage { Header { jmsDestination : TOPIC.XXXXXX jmsDeliveryMode : 1 jmsExpiration : 1274955064906 jmsPriority : 4 jmsMessageID : ID:2-12749550049061 jmsTimeStamp : 1274955004906 jmsCorrelationID: null jmsReplyTo : null jmsType : null jmsRedelivered : true jmsProperties : {JMSXDeliveryCount=484, JMS_JBOSS_REDELIVERY_LIMIT=0, JMS_JBOSS_REDELIVERY_COUNT=483} jmsPropReadWrite: false msgReadOnly : true producerClientId: ID:2 } } javax.resource.ResourceException: java.lang.IllegalStateException: [com.arjuna.ats.internal.jta.transaction.arjunacore.inactive] [com.arjuna.ats.internal.jta.transaction.arjunacore.inactive] The transaction is not active! at org.jboss.ejb3.mdb.inflow.MessageInflowLocalProxy.after(MessageInflowLocalProxy.java:232) at org.jboss.ejb3.mdb.inflow.MessageInflowLocalProxy.invoke(MessageInflowLocalProxy.java:134) at $Proxy153.afterDelivery(Unknown Source) at org.jboss.resource.adapter.jms.inflow.JmsServerSession.onMessage(JmsServerSession.java:183) at org.jboss.mq.SpyMessageConsumer.sessionConsumerProcessMessage(SpyMessageConsumer.java:906) at org.jboss.mq.SpyMessageConsumer.addMessage(SpyMessageConsumer.java:170) at org.jboss.mq.SpySession.run(SpySession.java:323) at org.jboss.resource.adapter.jms.inflow.JmsServerSession.run(JmsServerSession.java:237) at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:204) at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:275) at EDU.oswego.cs.dl.util.concurrent.PooledExecutor$Worker.run(PooledExecutor.java:761) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.IllegalStateException: [com.arjuna.ats.internal.jta.transaction.arjunacore.inactive] [com.arjuna.ats.internal.jta.transaction.arjunacore.inactive] The transaction is not active! at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commitAndDisassociate(TransactionImple.java:1385) at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction.java:135) at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.commit(BaseTransactionManagerDelegate.java:87) at org.jboss.ejb3.mdb.inflow.MessageInflowLocalProxy.endTransaction(MessageInflowLocalProxy.java:433) at org.jboss.ejb3.mdb.inflow.MessageInflowLocalProxy.finish(MessageInflowLocalProxy.java:312) at org.jboss.ejb3.mdb.inflow.MessageInflowLocalProxy.after(MessageInflowLocalProxy.java:228) Any ideas why this is happening (or if a jira bug has been opened for this)?

Maciej Swiderski [http://community.jboss.org/people/swiderski.maciej] replied to the discussion "SubProcess signaling issue" To view the discussion, visit: http://community.jboss.org/message/545036#545036 -------------------------------------------------------------- It looks like we are talking about two different things ;) What I am trying to say is that I would like to ensure that signalExecutionById(mainProcessId) will not signal running but not yet finished sub process. At the moment when your process has a sub process in a wait state and you signal as above then will signal sub process activity regardless of the state it currently is. Result of it will be: - main process will move on - sub process will be left unfinished - end method will not be invoked and this execution will not be deleted My suggestion is to prevent of signaling sub process activity when it is running. You don't need to fetch it from db since when signal method is executed you have access to both main and sub process instances. Will attach a patch today to jira. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545036#545036] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
