Dear,
I have 2 question one about DFsearch and other one about addBehaviour(). Let me explain:
1) I face with a moody behaviour of DF search. Actually I have a piece of code as follow :
try {
DFAgentDescription[] result = DFService.search(myAgent, template);
sellerAgents = new AID[result.length];
System.out.println("Found the following seller
agents:");
for (int i = 0; i < result.length; ++i) {
sellerAgents[i] =
result[i].getName();
System.out.println(sellerAgents[i].getName());
}
} catch (FIPAException fe) {
fe.printStackTrace();
which some times does returns the result and some times doesn't!
Do you know whats wrong? and how can I solve it?
2) I need to add a behaviour inside another Behaviour and I add it as follow:
myAgent.addBehaviour(new Behaviour() {
private int stage = 0;
public void action() {
switch (stage)
{
case 0:
// send reportback to coordinator
ACLMessage request = new
ACLMessage(ACLMessage.REQUEST);
request.addReceiver(sellerAgent);
try{
request.setContentObject(new Object[]{state,UtilityH [Pcnt], UtilityH [Pcnt-1],
UtilityH [Pcnt-2]});
request.setConversationId("Report");
request.setReplyWith("request"+System.currentTimeMillis()); // Unique
value
myAgent.send(request);
System.out.println("request sent! : "+state+", "+UtilityH [Pcnt]+", "+UtilityH [Pcnt-1]+", "+UtilityH [Pcnt-2]+"to:
"+sellerAgent);
}catch(Exception e){e.printStackTrace();
System.out.println("can not send reprot back from agent"+getAID().getName()
);}
stage++;
break;
case
1:
// receive Inheritance from coordinator MessageTemplate mt = MessageTemplate.MatchPerformative(ACLMessage.CONFIRM);
ACLMessage msg =
myAgent.receive(mt);
if(msg!=null){
Object[] msgContent;
try
{
msgContent = (Object[]) msg.getContentObject();
sellerStrategy =
msgContent[0].toString();
lowestUtilityValue = (Double) msgContent[1];
System.out.println("passe from coo: lowestUtilityValue:"+lowestUtilityValue+"seller
strategy:"+sellerStrategy);
} catch (UnreadableException ex) {
ex.printStackTrace();
}
}// if msg not null
else{
block();}
stage++;
break;
}// end of switch
}// end of action
public boolean done()
{
return stage == 2;
}// end of done
} );
But it seems that it jumps this behaviour without executing the behaviour. I dont know whats wrong. Do you have any idea?
Thank you, in advance.
