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...]

[JBoss Portal] - Reload portlet when developing with JBoss Tools

by Bogdan Sulima

Bogdan Sulima [http://community.jboss.org/people/bogdan.sulima] created the discussion "Reload portlet when developing with JBoss Tools" To view the discussion, visit: http://community.jboss.org/message/545029#545029 -------------------------------------------------------------- Hi All, i am developing JSR 286 portlet using JBoss Tools (Eclipse 3.5.2, JBoss Portal + JBoss AS bundle 2.7.2, Mac OS). If i change portlet class or other resources and publish portlet project to the portal from eclipse, portlet is not updated and not reloaded. Server is configured to publish changes automatically and eclipse shows some publishing progress, but from log file it is clear that no publishing actually happens. I always have to perform Server > Clean... in order to preview changes on the portal and this takes time and additional clicks. How can i setup automatic re-publishing? P.S.: deploying portlet as part or EAR does not help either :( no reloading happens. Best regards, Bogdan. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545029#545029] Start a new discussion in JBoss Portal at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Please refer this https://jira.jboss.org/browse/JBPM-2856 https://jira.jboss.org/browse/JBPM-2856. In my opinion, when a sub process ended, we should delete it and signal the super process. So there will be no process with ended state in database. If you cannot find a process intance, it means that it has already ended. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545028#545028] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

So my idea was to check in signal method of SubProcessActivity if sub process instance is in state ended, if so signaling is allowed otherwise throw an exception. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545024#545024] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM Development] - JBPM-2875 enhance classloader strategy for OSGi

by HuiSheng Xu

HuiSheng Xu [http://community.jboss.org/people/rebody] created the discussion "JBPM-2875 enhance classloader strategy for OSGi" To view the discussion, visit: http://community.jboss.org/message/545020#545020 -------------------------------------------------------------- Hi guys, I really need this feature to let jbpm4 run in an OSGi envrionment. Now jBPM4 only use Thread.currentThread().getContextClassLoader() to load resources or class. But in an OSGi environment, the contextClassLoader may be not for the jbpm4 bundle, So jBPM4 won't find any xml configuration resource from classloader, then lots of errors occured. So I need when jbpm4 find resource or class, it not only use contextClassLoader, but also use it's owner classloader, e.g. JpdlParser.class.getClassLoader(). Any opinions are appreciated. Thank you very much. https://jira.jboss.org/browse/JBPM-2875 https://jira.jboss.org/browse/JBPM-2875 -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545020#545020] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Remoting] - Need help in configuring JMS with JBoss Messaging in JBoss 4.2.3

by Prabhu Natarajan

Prabhu Natarajan [http://community.jboss.org/people/prabhun] created the discussion "Need help in configuring JMS with JBoss Messaging in JBoss 4.2.3" To view the discussion, visit: http://community.jboss.org/message/545019#545019 -------------------------------------------------------------- Hi, We were using JBoss MQ with JBoss 4.2.3. Now we have replaced JBoss MQ with JBoss Messaging by going through the migration instructions provided in the JBoss User guides. We have a number of Client systems (Java Swing based Reports) who were subscribed to the JMS (MQ implementation) in JBoss 4.2.3. Whenever a message arrives to the 'JBoss server TOPIC' all clients will receive that message. Message is sent by Oracle to JBoss server TOPIC through webservice call. Now as we have replaced MQ with Messaging, I would like to know what are all the configurations I should take care for the above scenario to work. *We have the following Environment details:* JBoss server : 4.2.3 JBoss Messaging: 1.4.2.GA-SP1 JBoss Remoting: 2.2.2.SP8 I have gone through the documents/guides and setup the following. *1. Server side setup:* connection-factories-service.xml Add the below entry to the above file (attached) mbean code - name="jboss.messaging.connectionfactory:service=CyrusConnectionFactory" Added the below entries to remoting-bisocket-service.xml file (attached) <attribute name="secondaryBindPort">14000</attribute> <attribute name="secondaryConnectPort">14001</attribute> *2. Client side setup:* Our client code which receives the message from TOPIC is in JMSTopicClient.java (attached) I have the following jars on the client side class path: jboss-messaging-client.jar jboss-remoting.jar jbossall-client.jar jboss-aop-jdk50.jar javassist.jar trove.jar *Now when I invoke the client I get the following exceptions:* *First exception:* 4047 [main] TRACE org.jboss.util.propertyeditor.PropertyEditors - Mapping properties for bean: SocketClientInvoker[b988a6, bisocket://uktapp02.tui.de:4457] 4047 [main] TRACE org.jboss.util.propertyeditor.PropertyEditors - Property editor found for: pingFrequency, editor: java.beans.PropertyDescriptor@d49b6d85, setter: public void org.jboss.remoting.transport.bisocket.BisocketClientInvoker.setPingFrequency(int) 4047 [main] TRACE org.jboss.util.propertyeditor.PropertyEditors - Property editor found for: numberOfCallRetries, editor: java.beans.PropertyDescriptor@b82b85fb, setter: public void org.jboss.remoting.transport.socket.MicroSocketClientInvoker.setNumberOfCallRetries(int) 4047 [main] TRACE org.jboss.util.propertyeditor.PropertyEditors - Property editor found for: marshaller, editor: java.beans.PropertyDescriptor@4ebe59ab, setter: public void org.jboss.remoting.MicroRemoteClientInvoker.setMarshaller(org.jboss.remoting.marshal.Marshaller) 4047 [main] TRACE org.jboss.util.propertyeditor.PropertyEditors - Failed to find property editor for: marshaller 4047 [main] TRACE org.jboss.util.propertyeditor.PropertyEditors - Failed to write property java.lang.NullPointerException at org.jboss.util.propertyeditor.PropertyEditors.mapJavaBeanProperties(PropertyEditors.java:373) at org.jboss.remoting.transport.socket.MicroSocketClientInvoker.setup(MicroSocketClientInvoker.java:405) *Second exception:* 25048 [main] ERROR org.jboss.jms.client.JBossConnectionFactory - Failed to download and/or install client side AOP stack org.jboss.jms.exception.MessagingNetworkFailureException at org.jboss.jms.client.delegate.DelegateSupport.handleThrowable(DelegateSupport.java:240) at org.jboss.jms.client.delegate.DelegateSupport.doInvoke(DelegateSupport.java:205) Caused by: org.jboss.remoting.CannotConnectException: Can not get connection to server.

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/545012#545012 -------------------------------------------------------------- you mean that when we enter sub process the main process should be in state inactive-scope? If so, I am afraid it won't work as expected, I really liked the idea though. The reason of this is if you mark main execution as inactive-scope when sub process activity is executed then automatic signal after sub process ends will fail since checkActive is executed in end activity which is prior to signal of sub process activity. Of course end activity code can be modified as well but I don't think it is a good idea. In my opinion engine should prevent of signaling main process while sub process is active, otherwise we could end up in really weird situations where some of the executions are left and main process is finished. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545012#545012] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I think it is maybe that there is no way to cancel a timer for a waiting execution. Seems we should consider about how to deal with it. And thank you for you patch. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545011#545011] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

But I don't know why there is no state for this scenario? If there is a particular state for waiting super-process, then we needn't to throw an exception by hand. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545004#545004] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
