Re: Runnig 2 or more agents on a platform.

2008-10-11T14:13:17Z

I can't not locate the problem, can someone help me?

my code:

Profile profile0 = new ProfileImpl(null, 1099, null);
Profile profile1 = new ProfileImpl(null, 5555, null);
Profile profile2 = new ProfileImpl(null, 1099, null);

jade.wrapper.AgentContainer mainContainer = rt.createMainContainer(profile0);

jade.wrapper.ContainerController container1 = rt.createAgentContainer(profile1);

jade.wrapper.ContainerController container2 = rt.createAgentContainer(profile2);

AgentController a= container1.createNewAgent("agent", "CallerAgent",param);
a.start();

AgentController b= container2.createNewAgent("agent2", "SnmpAgent",null);
b.start();

The output:

Hi Joseph,

I read your code and I think that the problem is that in you main.xml layout you are using a MapView component to show the maps.

This kind of component can be used only inside a special Activity class called MapActivity, that provides support for network communication.

Any time you have an issue with android emulator you can find out more information on it by issuing the command

adb logcat

from a command prompt.

If you do so after launching your application, you should be able to see the complete stacktrace when an exception is raised.

In your case in particular you should see:

Caused by: java.lang.IllegalArgumentException: MapViews can only be created inside instances of MapActivity.

To fix the problem, simply extend MapActivity instead of Activity in GeoICQ.java.

Please refer to:

http://code.google.com/android/documentation.html and www.anddev.org for more details.

Regards,

Stefano

Dear Jaders,

I'm beginner in developing multi agent systems with JADE.
I have a simle question that I need to be guided.
I want to develope a simple system with 5 or more agents.
The agents have a shared environment that any of them can change it.
So the agents must be aware about the changes of the environment.
I don't know how to develope an agent as a shared variable.
Could you help me, please?
Does it require an ontology?
Can I use AMS for that?

Thanks a lot,
Monireh Abdoos

I don't know about FIPA, but in multi-agent systems research there are
many approaches to agent coordination that do not depend on
communication. Look for terms such as "environment-based coordination",
"mediated interaction", "implicit communication".

Some works take inspiration on biological systems such as ant colonies,
where agents "communicate" by leaving marks in the environment they inhabit.

Cheers,

Henrique

Hi,

I feel compelled to add some agent theory discussion to this.

There is no such thing as a "dedicated agent ... that you pass a
reference to... to each agent (so the agents may have access to its
methods)".
If you do that, you end up with just an object, not an agent. An agent
is supposed to have autonomy regarding its state. Generally, you
interact with it through ACL Messages, not by calling its methods!

Using an agent for encapsulating a shared environment is ok (you
"agentify" the environment). This lets you access that "environment"
from any container. The agentified environment interacts with agents
through messages.

Cheers,

Henrique

Would you please NOT send mails of almost 3 MB size to the mailinglist?!
Since not everyone has much bandwidth and mail folders...

Thank you!

Hi,

Your approach is definitely simpler, but it works only in a single container. If your agents are distributed across different containers (as usual in JADE based applications) of course your shared environment is not shared anymore.

Bye,

Giovanni

Well, I don't really think that you need to specify an agent (not to mention an ontology) in order to "implement" a shared environment. Any class would do, with public getter and setters. Even more, although I don't really recommend it, is to use public variables declared in the class that instantiates your agents. Lastly, similar to the above approach but also not recommended as an approach, you could create a BasicAgent class that all other agents would sublcass, and declare static variables that represent your environment.

A dedicated agent (or simplier put a dedicated class) would be the best way to do it (in my opinion). Make sure that you pass a reference to that object to each agent (so the agents may have access to its methods).

Cheers,
George

HI,

JADE does not provide a ready-made shared space for agents. In my opinion the easiest way to implement it is by means of a dedicated agent (let's call it SharedSpaceAgent) that supports actions (you have to define a simple ontology) such as Put and Get. Furthetrmore that agent can support subscriptions.

BYe,

Giovanni

I: WSIG2.0: problem to call method having no parameter and no return values

2008-10-08T08:02:25Z

Hi Gopal,

Attention, as I have written, the fix is not in WSIG but in JADE.

You must update the JADE sources and rebuild it.

JADE SVN repository: https://avalon.tilab.com/svn/jade/trunk

Recompile JADE with "ant lib"

Bye

Enrico

Oggetto: RE: WSIG2.0: problem to call method having no parameter and no return values

Hi Enrico

I have downloaded source code of WSIG from SVN and updated the package “com.tilab.wsig” and all its sub packages.

Rebuild the entire project. It is still showing me exposed method names in lower case those were exposed with out mapper class.

Am I doing something wrong?

Please suggest.

Thanks & Regards

Gopal Varshney

Subject: R: WSIG2.0: problem to call method having no parameter and no return values

Hi Gopal,

The problem is in JADE getActionSchema() method that return a list in lower case.
We have fixed the problem in jade and changes are available on the svn repository.
If you want to use this new features you need to update the sources of jade and rebuild everything.
Otherwise the only way is to use the mapper with the annotation @ OperationName (...).

Bye

Enrico
