Hi Christian, Thanks for you answer. I have fixed the 2 issues (correct jpa namespace and pax-jdbc for datasource) but unfortunately, the error is still there. The new code is committed on github. Regards, -- Nicolas

In blueprint.xml you use the namespace xmlns:jpa="http://aries.apache.org/xmlns/jpan/v1.0.0";. This is deprecated. The correct one is xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0"; 2. Your DataSource is not fully JTA enabled. (You are using org.apache.commons.dbcp2.managed.BasicManagedDataSource) You can see how to setup dbcp2 in https://github.com/ops4j/org.ops4j.pax.jdbc/blob/master/pax-jdbc-pool-dbcp2/src/main/java/org/ops4j/pax/jdbc/pool/dbcp2/impl/ds/DbcpXAPooledDataSourceFactory.java I suggest to simply use pax-jdbc-pool-dbcp2 und pax-jdbc-config to create your DataSource. See https://ops4j1.jira.com/wiki/display/PAXJDBC/Pooling+and+XA+support+for+DataSourceFactory Can you try if fixing these two issues helps? If not then it might be a bug and I will investigate it deeper.

I ran into a problem with JPA and transaction management so I have created a small maven project showing it. This sample is available on GitHub : https://github.com/nicolas-dutertry/test-jpa The class TestServiceImpl in test-jpa-service has an EntityManager annoted with @PersistenceContext(unitname = "test") The class DeleteManager also has an EntityManager annoted with @PersistenceContext(unitname = "test") The method TestServiceImpl.delete is not transactional and it calls the transactional method DeleteManager.delete several times : public class TestServiceImpl implements TestService { @PersistenceContext(unitName = "test") private EntityManager entityManager; private DeleteManager deleteManager; … @Override public void delete(String... names) { for (String name : names) { System.out.println("Deleting " + name); deleteManager.delete(name); } } } public class DeleteManager { @PersistenceContext(unitName = "test") private EntityManager entityManager; … @Transactional public void delete(String lastName) { Query query = entityManager.createQuery( "delete from Person where lastName = :lastName"); query.setParameter("lastName", lastName); query.executeUpdate(); } } At runtime it raised a javax.persistence.TransactionRequiredException during the second call to DeleteManager.delete in the for loop. To reproduce the problem, compile the sample project with maven: > mvn clean install Then, launch Karaf 4.0.4 and install the kar: > kar:install mvn:com.dutertry.test.karaf.jpa/test-jpa-kar/1.0.0-SNAPSHOT/kar Then, create new entries in database: > person:create Smith 25 > person:create Green 23 Finally delete them: > person:delete Smith Green This will output : Deleting Smith Deleting Green Error executing command: Executing an update/delete query With the following log : 2016-02-05 14:52:32,753 | ERROR | nsole user karaf | ShellUtil | 44 - org.apache.karaf.shell.core - 4.0.4 | Exception caught while executing command javax.persistence.TransactionRequiredException: Executing an update/delete query at org.hibernate.jpa.spi.AbstractQueryImpl.executeUpdate(AbstractQueryImpl.java:71) at com.dutertry.test.karaf.jpa.service.impl.DeleteManager.delete(DeleteManager.java:33) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)[:1.7.0_67] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)[:1.7.0_67] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)[:1.7.0_67] at java.lang.reflect.Method.invoke(Method.java:606)[:1.7.0_67] at org.apache.aries.proxy.impl.ProxyHandler$1.invoke(ProxyHandler.java:54)[21:org.apache.aries.proxy.impl:1.0.4] at org.apache.aries.proxy.impl.ProxyHandler.invoke(ProxyHandler.java:119)[21:org.apache.aries.proxy.impl:1.0.4] at com.dutertry.test.karaf.jpa.service.impl.$DeleteManager1431996488.delete(Unknown Source)[131:test-jpa-service:1.0.0.SNAPSHOT] at com.dutertry.test.karaf.jpa.service.impl.TestServiceImpl.delete(TestServiceImpl.java:53)[131:test-jpa-service:1.0.0.SNAPSHOT] at Proxy77c92452_69bd_43a7_b242_ba213735af8a.delete(Unknown Source)[:] at com.dutertry.test.karaf.jpa.cmd.DeletePersonCommand.execute(DeletePersonCommand.java:30)[128:test-jpa-cmd:1.0.0.SNAPSHOT] at org.apache.karaf.shell.impl.action.command.ActionCommand.execute(ActionCommand.java:83)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.karaf.shell.impl.console.osgi.secured.SecuredCommand.execute(SecuredCommand.java:67)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.karaf.shell.impl.console.osgi.secured.SecuredCommand.execute(SecuredCommand.java:87)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.felix.gogo.runtime.Closure.executeCmd(Closure.java:480)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.felix.gogo.runtime.Closure.executeStatement(Closure.java:406)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.felix.gogo.runtime.Pipe.run(Pipe.java:108)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.felix.gogo.runtime.Closure.execute(Closure.java:182)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.felix.gogo.runtime.Closure.execute(Closure.java:119)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.felix.gogo.runtime.CommandSessionImpl.execute(CommandSessionImpl.java:94)[44:org.apache.karaf.shell.core:4.0.4] at org.apache.karaf.shell.impl.console.ConsoleSessionImpl.run(ConsoleSessionImpl.java:270)[44:org.apache.karaf.shell.core:4.0.4] at java.lang.Thread.run(Thread.java:745)[:1.7.0_67] Regards, -- Nicolas Dutertry Sopra HR Software - http://www.soprahr.com/ -- -- Christian Schneider http://www.liquid-reality.de<https://owa.talend.com/owa/redir.aspx?C=3aa4083e0c744ae1ba52bd062c5a7e46&URL=http%3a%2f%2fwww.liquid-reality.de> Open Source Architect http://www.talend.com<https://owa.talend.com/owa/redir.aspx?C=3aa4083e0c744ae1ba52bd062c5a7e46&URL=http%3a%2f%2fwww.talend.com>
