问题
I'm trying to use DataObjects in Java:
DataFactory factory = DataFactory.INSTANCE;
in one java Project using:
import commonj.sdo.DataObject;
And I'm getting this error:

回答1:
Are you using Process Server? I'm pretty sure com.ibm.ws.sca.internal.container.impl.ContainerImpl is a Process Server class...
回答2:
I think the application is based on EMF SDO?
Instead of Java application, you may run your application as a Eclipse application in your IDE, because the application require OSGi bundle loading mechanism to load the required bundle (i.e. org.eclipse.core.runtime) in the runtime.

I faced a similar issue when trying to instantiate the BOFactory class from JUnit. I was able to resolve it by adding org-eclipse-equinox-registry.jar files to my projects, along with the SDO jar files.
