I am in search for documentation which e.g. explains why in the quickstart examples no web.xml was necessary or what are the specifics of using hibernate with AS7. After migrating my multimodule project from tomcat I cannot deploy it on AS7 due to the below error message. Looks like something is missing in persistence.xml - where can I find information on what exactly it is (name, content,...)? 08:45:36,103 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC00001: Failed to start service jboss.persistenceunit."jatpresent.war#jatPU": org.jboss.msc.service.StartException in service jboss.persistenceunit."jatpresent.war#jatPU": Failed to start service at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1767) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [rt.jar:1.6.0_26] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [rt.jar:1.6.0_26] at java.lang.Thread.run(Thread.java:662) [rt.jar:1.6.0_26] Caused by: java.lang.UnsupportedOperationException: The application must supply JDBC connections at org.hibernate.service.jdbc.connections.internal.UserSuppliedConnectionProviderImpl.getConnection(UserSuppliedConnectionProviderImpl.java:62) at org.hibernate.tool.hbm2ddl.SuppliedConnectionProviderConnectionHelper.prepare(SuppliedConnectionProviderConnectionHelper.java:51) at org.hibernate.tool.hbm2ddl.SchemaValidator.validate(SchemaValidator.java:146) at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:460) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1737) at org.hibernate.ejb.EntityManagerFactoryImpl.<init>(EntityManagerFactoryImpl.java:84) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:904) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:889) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:73) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl.createContainerEntityManagerFactory(PersistenceUnitServiceImpl.java:162) at org.jboss.as.jpa.service.PersistenceUnitServiceImpl.start(PersistenceUnitServiceImpl.java:85) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1811) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] at org.jboss.msc.service.ServiceControllerImpl$StartTask.run(ServiceControllerImpl.java:1746) [jboss-msc-1.0.2.GA.jar:1.0.2.GA] ... 3 more 08:45:36,400 INFO  [org.jboss.as.server] (management-handler-threads - 7) JBAS015870: Deploy of deployment "jatpresent.war" was rolled back with failure message {"JBAS014671: Failed services" => {"jboss.persistenceunit.\"jatpresent.war#jatPU\"" => "org.jboss.msc.service.StartException in service jboss.persistenceunit.\"jatpresent.war#jatPU\": Failed to start service"}} Regards, Michael -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/717402#717402] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
