alright Al,

I think what you want to do is this:

import org.jbpm.api.Configuration;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.RepositoryService;
import org.jbpm.api.task.Task;
import org.jbpm.pvm.internal.cmd.CommandService;
import org.jbpm.pvm.internal.cmd.GetTaskCmd;
import org.jbpm.pvm.internal.env.EnvironmentImpl;
import org.jbpm.pvm.internal.processengine.ProcessEngineImpl;
 
public class Start {
 
    private static volatile ProcessEngineImpl engine;
 
    public static void main(final String[] args) {
        engine = (ProcessEngineImpl) new Configuration().setResource("jbpm4.jvm.cfg.xml").buildProcessEngine();
        System.out.println("instanciated Engine in main: " + engine);
        new Start().doSomeStuff();
    }
 
    private void doSomeStuff() {
        try {
            EnvironmentImpl environment = engine.openEnvironment();
            System.out.println("environment is: " + environment);
 
            RepositoryService repositoryService = EnvironmentImpl.getFromCurrent(RepositoryService.class);
            System.out.println("RepositoryService is : " + repositoryService);     
            long pdCount = repositoryService.createProcessDefinitionQuery().count();
            System.out.println("pdcount is: " + pdCount);
 
            CommandService commandService = EnvironmentImpl.getFromCurrent(CommandService.class);
            System.out.println("commandService is : " + commandService);
            Task task = commandService.execute(new GetTaskCmd("4711"));
            System.out.println("task 4711 is : " + task);
        } finally {
            engine.close();
        }
    }
 
}
