[JBoss JIRA] Created: (JBPM-2764) extend API to make it possible to determine the type of an active activity

extend API to make it possible to determine the type of an active activity -------------------------------------------------------------------------- Key: JBPM-2764 URL: https://jira.jboss.org/jira/browse/JBPM-2764 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.0, jBPM 4.1, jBPM 4.2, jBPM 4.3 Environment: not relevant Reporter: Sebastian Schneider Fix For: jBPM 4.x The API should be extended in that way that you can easily determine the type of an active activity. To achieve this getActiveActivities() could be extended to also return the type of an activity additionally to its name and description. Or there could be a method taking an activity's name and returning its type. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2658) Process variables of type hibernate-long-id/hibernate-string-id don't work

by Derek Cornelius (JIRA)

Process variables of type hibernate-long-id/hibernate-string-id don't work -------------------------------------------------------------------------- Key: JBPM-2658 URL: https://jira.jboss.org/jira/browse/JBPM-2658 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Reporter: Derek Cornelius This is the same problem as JBPM-2474. The problem is in HibernateIdMatcher. if (sessionFactory!=null) { ClassMetadata classMetadata = sessionFactory.getClassMetadata(value.getClass()); matches = ( (classMetadata!=null) && (classMetadata.getIdentifierType().getClass()==getIdType()) ); } value.getClass() is returning the Javassist proxy class that is not found.

[JBoss JIRA] Created: (JBPM-2945) EJB3 based job processor

by Alejandro Guizar (JIRA)

EJB3 based job processor ------------------------ Key: JBPM-2945 URL: https://jira.jboss.org/browse/JBPM-2945 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Reporter: Alejandro Guizar Fix For: jBPM 3.2.10 There have some issues with how the retry mechanism works with Timers, and we recommend not ditching the XA driver for 2 phase commit. We will be changing how the JMS Listener works for jBPM; currently, it used JCA Inflow Adapter, which is an element of JBoss SOA-P. We would like to instead use Message Driven Beans; this is a really stable project and an element of EJB 3.0. We believe that the issue with hung commits probably internally has something to do with JCA Inflow Adapter and its transaction management. By using MDB, we will get Container Managed Transactions, which is a stable and standard TX implementation which is well documented. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2946) class org.jbpm.ejb.impl.CommandListenerBean.java the lookup has the JNDI name harcoded

by eric schabell (JIRA)

class org.jbpm.ejb.impl.CommandListenerBean.java the lookup has the JNDI name harcoded -------------------------------------------------------------------------------------- Key: JBPM-2946 URL: https://jira.jboss.org/browse/JBPM-2946 Project: jBPM Issue Type: Patch Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 3.2.x Reporter: eric schabell Priority: Minor Fix For: jBPM 3.2.10 Working with jBPM 3.2.8 but I have found it still is the same in jBPM 3.x TRUNK. This issue was raised in issue 00063190, but is resolved in JBoss environments only with their answer. To be more flexible the fix below would be nice. Class org.jbpm.ejb.impl.CommandListenerBean.java the lookup has the JNDI name harcoded: LocalCommandServiceHome commandServiceHome = (LocalCommandServiceHome) initial.lookup("java:comp/env/ejb/LocalCommandServiceBean"); So this can't be configured through jbpm-cfg.xml. This causes problems when the EJB JNDI name is different from ejb/LocalCommandServiceBean. I wonder if it's possible to fix it so it works like the org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory.java, which has this: String timerEntityHomeJndiName = "java:comp/env/ejb/TimerEntityBean"; [...] timerEntityHome = (LocalTimerEntityHome) lookup(timerEntityHomeJndiName); This way it can be configured through jbpm-cfg.xml: <service name="scheduler"> <factory> <bean class="org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory"> <field name="timerEntityHomeJndiName"> <string value="TimerEntityBean"/> </field> </bean> </factory> </service> This is sort of like the issue resolved here https://jira.jboss.org/browse/JBPM-960 Patch would be something like this in CommandListenerBean.java starting at line 179 (entire method provided here): private Session createSession() throws JMSException { if (jmsConnection == null) { // lookup factory and create jms connection try { log.debug("trying to create session with CommanListenerBean"); Context initial = new InitialContext(); // Changed the following line to change the hardcoded comp:env/ejb JNDI // ConnectionFactory jmsConnectionFactory = (ConnectionFactory) initial.lookup("java:comp/env/jms/JbpmConnectionFactory"); ConnectionFactory jmsConnectionFactory = (ConnectionFactory) initial.lookup("jbpmJobExecConFact"); jmsConnection = jmsConnectionFactory.createConnection(); log.debug("done creating session with CommanListenerBean"); } catch (NamingException e) { throw new EJBException("error retrieving jms connection factory", e); } } /* * if the connection supports xa, the session will be transacted, else the session will auto * acknowledge; in either case no explicit transaction control must be performed - see ejb 2.1 - * 17.3.5 */ return jmsConnection.createSession(false, Session.AUTO_ACKNOWLEDGE); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2934) Reorganize jbpm3 modules and continuous integration

by Alejandro Guizar (JIRA)

Reorganize jbpm3 modules and continuous integration --------------------------------------------------- Key: JBPM-2934 URL: https://jira.jboss.org/browse/JBPM-2934 Project: jBPM Issue Type: Quality Risk Reporter: Alejandro Guizar Assignee: Alejandro Guizar Priority: Minor Fix For: jBPM 3.2.10 The current layout places the project modules in a "modules" directory which is not standard practice and prevents certain desirable functionality such as m2eclipse "hide folders of physically nested modules" check box. On a separate topic, the "hudson" directory and its subdirectories could use shorter, better names. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
