[jbpm-issues] [JBoss JIRA] Closed: (JBPM-1046) JobExecutorServlet cannot use local JNDI name to access datasource

JobExecutorServlet cannot use local JNDI name to access datasource ------------------------------------------------------------------ Key: JBPM-1046 URL: https://jira.jboss.org/jira/browse/JBPM-1046 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.2.1 Environment: Windows 2000 IBM Websphere Application Server 6.1 (also reproduced on Websphere Test Environment 5.1) Oracle 9i database (with ojdbc14.jar release 9.2.0.8) Reporter: Jacques Desmazi?res Assignee: Alejandro Guizar Fix For: jBPM 3.2.3 When configuraing jBPM / Hibernate with a datasource in an Enterprise application, using a local JNDI reference (java:comp/env/...) the web application works properly, accessing the database without any problem. But if you declare the JobExecutorServlet in the web application's web.xml, each time the this servlet JobExecutorThread fires, it generates exceptions: [22/08/07 18:33:03:175 CEST] 0000005e SystemOut O 18:33:03 DEBUG org.jbpm.job.executor.JobExecutorThread : acquiring jobs for execution... [22/08/07 18:33:03:315 CEST] 0000005f javaURLContex E NMSV0310E: Une opération JNDI sur un nom "java:" ne peut pas aboutir car le contexte d'exécution du serveur ne peut pas associer l'unité d'exécution de l'opération à un composant d'application J2EE. Cette condition peut se produire lorsque le client JNDI utilisant le nom "java:" n'est pas exécuté sur l'unité d'exécution d'une demande d'application du serveur. Assurez-vous qu'une application J2EE n'exécute pas d'opérations JNDI sur des noms "java:" dans des blocs de code statiques ou dans des unités d'exécution créées par cette application J2EE. Un code de ce type ne s'exécute pas nécessairement sur l'unité d'exécution d'une demande d'application du serveur et n'est donc pas pris en charge par les opérations JNDI sur les noms "java:".

If I replace the local JNDI reference (java:comp/env/jdbc/datasource) with the global JNDI name (jdbc/dsOracle) the JobExecutorThread works fine (even if Websphere logs warning due to direct use of the global JNDI reference). The JobExecutorThread also works if I replace the datasource with the database access parameters (driver, url, ...). (sample ear is available to reproduce the bug if necessary)
