Process Designer do not show in jBPM 6.0.1 workbench

by anguang1973

Hello Everyone, I am new for jBPM. I have installed jbpm-6.0.1.Final-installer-full for learning. I installed the program by running ant install.demo. There is no error messages in the installation. I can access the workbench. But when I choose to new a build process, the process designer view cannot open. There is only a blank area in the browser. Who can help me? Thanks! anguang 2014-06-26 anguang1973

Why does the jbpm-test-6.0.1-20140120.jar need to be referenced for the solution to work? 3. Because of question 2 giving me problems I googled some and found this Issue running sample project - jBPM 6.0.1 Final, this comment in particular: Re: Issue running sample project - jBPM 6.0.1 Final As per that post Re: Re: Issue running sample project - jBPM 6.0.1 Final, created the persistence.xml (attached) but the test code still didnt work. I copied the code and tried to run the code as follows in a main() with an EntityManager as recommended in the post (as attached Run.java) Then i get this Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [jdbc/jbpm-ds] Most likely the persistence.xml in the test jar mentioned in (2), so i remove it from includes and rerun Exception on Run.java line 67 Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named org.jbpm.persistence.jpa Then i try to swap my boolean old to false to run the code with an EntityManager defined (Run.java line 40): Exception raised on EntityManager Exception in thread "main" javax.persistence.PersistenceException: [PersistenceUnit: org.jbpm.persistence.jpa.updated] Unable to build EntityManagerFactory at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:930) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:904) at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:72) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:63) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:47) at com.sample.Run.main(Run.java:41) Caused by: org.hibernate.service.jndi.JndiException: Error parsing JNDI name [java:jboss/datasources/jbpmDS] at org.hibernate.service.jndi.internal.JndiServiceImpl.parseName(JndiServiceImpl.java:92) at org.hibernate.service.jndi.internal.JndiServiceImpl.locate(JndiServiceImpl.java:63) at org.hibernate.service.jdbc.connections.internal.DatasourceConnectionProviderImpl.configure(DatasourceConnectionProviderImpl.java:116) at org.hibernate.service.internal.StandardServiceRegistryImpl.configureService(StandardServiceRegistryImpl.java:75) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:159) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:131) at org.hibernate.engine.jdbc.internal.JdbcServicesImpl.buildJdbcConnectionAccess(JdbcServicesImpl.java:223) at org.hibernate.engine.jdbc.internal.JdbcServicesImpl.configure(JdbcServicesImpl.java:89) at org.hibernate.service.internal.StandardServiceRegistryImpl.configureService(StandardServiceRegistryImpl.java:75) at org.hibernate.service.internal.AbstractServiceRegistryImpl.initializeService(AbstractServiceRegistryImpl.java:159) at org.hibernate.service.internal.AbstractServiceRegistryImpl.getService(AbstractServiceRegistryImpl.java:131) at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:78) at org.hibernate.cfg.Configuration.buildSettingsInternal(Configuration.java:2295) at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2291) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1760) at org.hibernate.ejb.EntityManagerFactoryImpl.<init>(EntityManagerFactoryImpl.java:94) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:920) ... 5 more Caused by: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:662) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:307) at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:344) at javax.naming.InitialContext.getNameParser(InitialContext.java:499) at org.hibernate.service.jndi.internal.JndiServiceImpl.parseName(JndiServiceImpl.java:86) So how do i get it to point to the data source defined in the demo ( <jta-data-source>java:jboss/datasources/jbpmDS</jta-data-source>)?

Re: [jbpm-dev] process instance BPMN and variable scope memory leak

by Mauricio Salatino

Can you please attach a maven project? or the link to a maven project that we can just clone from github and run? That will give us more time to evaluate the problem, instead of wasting time in setting up the project.

process instance BPMN and variable scope memory leak

by paul.chaunguyen＠externe.bnpparibas.com

Dear all, We are facing big issue with variable scope so application failed to out of memory with BPMN. Our situtation is below 1/ Initially, we put an object (prototype) as global inside BPMN --> after bpmn execution object is still there JVM garbage collection can not removed it 2/ We try to change this in moving object (prototype) to process parameters map, --> still the same issue: after bpmn execution object is still there JVM garbage collection can not removed it 3/ We try to use this object as facts but can not get the good syntax in java dialect to process as document or user guide related BPMN is very poor, Can you help please ?
