Hi,

I'm using jBPM 4.1 in a standalone application with the default setup, having switched to MySQL as DB. I need to update some values in the jBPM DB manually and was asking myself what the most convenient and conformant way would be. As I want to access the environment, I thought about doing so using a custom command like this:

public class UpdateDbCmd implements Command<Object> {

 private Object _entry;

 public UpdateDbCmd(Object entry) {
 _entry = entry;
 }

 public Object execute(Environment environment) throws Exception {
 DbSession session = (DbSession) environment.get(DbSession.class);
// [...]update the entry
 return null;
 }

}

Then I try to execute the Command like this:

ProcessEngine eng = new Configuration().buildProcessEngine();
// [...]
eng.execute(new UpdateDbCmd(someEntry));

This does result in a NullPointerException as the userCommandService is not defined in the configuration. Unfortunately I haven't found information about how to configure the wire bindings correctly. Could anyone please point me in the right direction or suggest another way how to update db entries manually.

Thanks
