NPE on createEntityManager

lburgazzoli commented 11 years ago

I've installed the following bundles in Karaf 2.3.0

And then when I try to run a little test that work with OpenJPA and Eclipselink I have an NPE exception:

java.lang.NullPointerException at org.apache.aries.jpa.container.impl.CountingEntityManagerFactory.createEntityManager(CountingEntityManagerFactory.java:65)[59:org.apache.aries.jpa.container:1.0.0] at Proxy735ba6d6_df91_4682_9974_d420f75b1cf1.createEntityManager(Unknown Source)[:] at lb.examples.karaf.jpa.hibernate.data.ApplicationManagedDataService.add(ApplicationManagedDataService.java:55)[233:jpa-hibernate:1.0.0.SNAPSHOT] at lb.examples.karaf.jpa.hibernate.cmd.ItemAddCommand.execute(ItemAddCommand.java:55)[233:jpa-hibernate:1.0.0.SNAPSHOT] at org.apache.felix.gogo.commands.basic.AbstractCommand.execute(AbstractCommand.java:35)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.CommandProxy.execute(CommandProxy.java:78)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.Closure.executeCmd(Closure.java:474)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.Closure.executeStatement(Closure.java:400)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.Pipe.run(Pipe.java:108)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.Closure.execute(Closure.java:183)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.Closure.execute(Closure.java:120)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.felix.gogo.runtime.CommandSessionImpl.execute(CommandSessionImpl.java:89)[14:org.apache.karaf.shell.console:2.3.0] at org.apache.karaf.shell.console.jline.Console.run(Console.java:175)[14:org.apache.karaf.shell.console:2.3.0] at java.lang.Thread.run(Thread.java:722)[:1.7.0_15]

I do not know if it is because of a misconfiguration in my sample or a bug:

the same is for Karaf 2.3.1

@lgazo , is your bundle in a public repo? I'd be happy to pull it down and debug a bit. Some extra use cases are always helpful.

lgazo commented 11 years ago

I've quickly copied sources here: https://github.com/lgazo/karaf-poc

Status:

Curently it is switched to OpenJPA but there is commented Hibernate setup
I have to call "update" command on fis-persistenceunit after start so the event-service gets started correctly
having dev:watch on event-service and reinstalling it (via mvn install) causes the bundle to stop but never finishes the stop process..

fyi. I am quite new to osgi so some things might be set up incorrectly - I welcome any comments in this regard :)

I do not more have any NPE exception since the migration to 4.2.1-SNAPSHOT
