Hi David, I tried your suggesting, but without success.
The problem is that the datasource is'nt really injected into the SLSB. All happened in the jbpmConfiguration.createJbpmContext() method. The InitialContext get always some properties, as far as I see in the debug view, so it always use the constructor with the parameter.

When running in a SLSB you should be able to access it's JNDI namespace. To do that the InitialContext needs to be constructed with no (or empty) properties. Then you should be able add a <resource- ref> like: <resource-ref> <res-ref-name>TestDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> </resource-ref> And then look it up from within the SLSB with 'java:comp/env/TestDS' -David On Mar 12, 2009, at 4:47 AM, <[email protected]> <[email protected] > wrote: > It's me again, > > I tried to go a step back and want to get only the jbpm SLSB to run. > After I hack against the issue > https://issues.apache.org/jira/browse/OPENEJB-971 > , I can start up the ejb components of jbpm in openejb: > > 2009-03-12 11:40:21,259 INFO OpenEJB.startup:70 - Deployed > Application(path=classpath.ear) > 2009-03-12 11:40:21,259 DEBUG OpenEJB.startup:82 - > Containers : 5 > 2009-03-12 11:40:21,259 DEBUG OpenEJB.startup:82 - Type Container ID > 2009-03-12 11:40:21,259 DEBUG OpenEJB.startup:82 - CMP ENTITY My > CMP Container > 2009-03-12 11:40:21,259 DEBUG OpenEJB.startup:82 - STATEFUL My > Stateful Container > 2009-03-12 11:40:21,259 DEBUG OpenEJB.startup:82 - MESSAGE My > MDB Container > 2009-03-12 11:40:21,259 DEBUG OpenEJB.startup:82 - BMP ENTITY My > BMP Container > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - STATELESS My > Stateless Container > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - > Deployments : 6 > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - Type Deployment ID > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - MESSAGE > JobListenerBean > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - CMP_ENTITY > TimerEntityBean > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - STATELESS > TimerServiceBean > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - STATELESS > CommandServiceBean > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - MESSAGE > CommandListenerBean > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - STATEFUL > JbpmFacadeImpl > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - > SecurityService : > org.apache.openejb.core.security.SecurityServiceImpl > 2009-03-12 11:40:21,275 DEBUG OpenEJB.startup:82 - > TransactionManager: > org.apache.geronimo.transaction.manager.GeronimoTransactionManager > 2009-03-12 11:40:21,290 DEBUG OpenEJB.startup:82 - OpenEJB Container > System ready. > > But when I access the SLSB I got finally into the same exception as in > my first post, when the jbpm context is built: > > 2009-03-12 12:46:09,068 FATAL > org.hibernate.connection.DatasourceConnectionProvider:55 - Could not > find datasource: java:openejb/Resource/TestDS > javax.naming.NameNotFoundException: Name "java:openejb/Resource/ > TestDS" not found. > at > org > .apache.openejb.core.ivm.naming.IvmContext.federate(IvmContext.java: > 172) > at > org.apache.openejb.core.ivm.naming.IvmContext.lookup(IvmContext.java: > 129) > at javax.naming.InitialContext.lookup(InitialContext.java:351) > at > org > .hibernate > .connection > .DatasourceConnectionProvider > .configure(DatasourceConnectionProvider.java:52) > at > org > .hibernate > .connection > .ConnectionProviderFactory > .newConnectionProvider(ConnectionProviderFactory.java:124) > at > org > .hibernate > .connection > .ConnectionProviderFactory > .newConnectionProvider(ConnectionProviderFactory.java:56) > at > org > .hibernate > .cfg.SettingsFactory.createConnectionProvider(SettingsFactory.java: > 414) > at > org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java: > 62) > at > org.hibernate.cfg.Configuration.buildSettings(Configuration.java:2073) > at > org > .hibernate.cfg.Configuration.buildSessionFactory(Configuration.java: > 1298) > at > org > .jbpm > .persistence > .db > .DbPersistenceServiceFactory > .getSessionFactory(DbPersistenceServiceFactory.java:105) > at > org > .jbpm > .persistence > .db.DbPersistenceService.getSessionFactory(DbPersistenceService.java: > 95) > at > org > .jbpm > .persistence > .jta > .JtaDbPersistenceService > .isJtaTransactionInProgress(JtaDbPersistenceService.java:64) > at > org > .jbpm > .persistence > .jta.JtaDbPersistenceService.<init>(JtaDbPersistenceService.java:46) > at > org > .jbpm > .persistence > .jta > .JtaDbPersistenceServiceFactory > .openService(JtaDbPersistenceServiceFactory.java:63) > ... > > There is some part in the hibernate code to get the InitialContext: > > package org.hibernate.util; > ... > public final class NamingHelper > { > > ... > > public static InitialContext getInitialContext(Properties props) > throws NamingException > { > Hashtable hash = getJndiProperties(props); > log.info("JNDI InitialContext properties:" + hash); > try > { > return hash.size() != 0 ?
