Hi! I have problem with this very simple code.
When I try to run it I have an strange exception.
import org.apache.ojb.broker.metadata.DescriptorRepository;
import org.apache.ojb.broker.metadata.MetadataManager;
public class test_copyOfGlobalRepository
{
public static void main(String args[])
{
try
{
MetadataManager mm = MetadataManager.getInstance();
mm.setEnablePerThreadChanges(true);
DescriptorRepository dr = mm.copyOfGlobalRepository();
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}
