Null pointer

[yanet]

Hi, I am traying this simple example and i hav a null pointer exception , I can´t see where

@Agent
public class TestBDI {
@AgentFeature
protected IBDIAgentFeature bdi;

String f;

@Belief 
Map <String, String> frases;


@AgentCreated
public void init (){

    frases = new HashMap<String, String>();
    frases.put("Nombre", "Alice");
    frases.put("Edad", "40");
    frases.put("Cancer","No puede ser");
    frases.put("Buenas", "Buen dia");
    frases.put("Nada", "Gracias a Dios!");
    frases.put("Lo siento", "Usted está equivocado. Adios");


}



@Goal
class Responder{
    protected String frase;

    public Responder(String f){
        frase = f;
    }

    public void setFrase(String f){
        frase = f;
    }

    public String getFrase(){
        return frase;
    }

}

@Plan(trigger=@Trigger(goals=Responder.class))
public void Responder(Responder g){

   System.out.println(frases.get(g.frase) );

}

@AgentBody

public IFuture<Void> Do(){

    Scanner preg = new Scanner(System.in);
    f = preg.next();        
    Responder resp= (Responder) bdi.dispatchTopLevelGoal(new Responder(f)).get();

return IFuture.DONE;

}

}

The null pointer is on

Responder resp= (Responder) bdi.dispatchTopLevelGoal(new Responder(f)).get();

Thx

Hi, It run ok, whit JCC , but I want it run whit java debugger , because I need to see step by step the execution, How can I do this??

Thx, a lot

hello???

[Lars Braubach]

The same way as any other Java program. Use 'debug' in eclipse and use jadex.base.Starter as start class.

Hi, first , Thanks for helping me, I did , but I have the same error,

[Lars Braubach]

Open 'this' in variable view and check which fields are null. Is bdi null? Is f null? etc.

[yanet]

bdi,

[Lars Braubach]

Then injection does not work. Is the annotation in place?

[yanet]

I think so,

[yanet]

It works in JCC,

I can´t find the problem... Maybe I am doing somthing wrong, how do you debug this code in eclipse
