I’ve installed standalone Equinox and used it as run configuration in eclipse. Project uses EclipseLink as JPA and it’s configured to use derby and mysql providers. These providers are packed into bundles and activated in OSGi container. When i run project from eclipse and activate my bundle, the JPA factory is created normally and project works fine.
But! When i run equinox standalone eclipselink can’t load database connector driver. Drivers as is wrote are packed as bundles and activated.
I notice, the Eclipse uses the same configuration which i use to run Equinox standalone and the same set of bundles. And the same bundle internal tree the eclipse used to run.
As i understood java classpath isn’t needed in OSGi container – there are bundles used. And they are imported in my plugin’s manifest.mf.
What’s the problem, i can’t understand. Why the application cannot find driver classes?
Ok, i provide complete exception callstack for derby driver. It seems EL functions normal. For mysql driver the problem is the same, but callstack differs a bit. When i run the same program from eclipse it works right.
That’s my configuration:

I use that code to create entity factory:
mSystemEntities = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME);
EntityManager em = mSystemEntities.createEntityManager();
And here’s my persistence.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0" xmlns="http://java.sun.com/xml/ns/persistence">
<persistence-unit name="prov" transaction-type="RESOURCE_LOCAL">
<class>ru.futurelink.moneyorganizer.data.MOUserEntity</class>
<properties>
<property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.EmbeddedDriver" />
<property name="javax.persistence.jdbc.url" value="jdbc:derby:/sampledb;create=true" />
<!-- EclipseLink should create the database schema automatically -->
<property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
<property name="eclipselink.ddl-generation.output-mode" value="database" />
</properties>
</persistence-unit>
</persistence>
I’ve found the solution. The Eclipse starts OSGi framework with org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar, but i try to load org.eclipse.osgi_3.8.100.v20120912-141032.jar. I think that framework without launcher doesnt support reflection cause classloader is missing. I’m not shure that the mechanism is of that kind but JPA works now and loads all drivers.
