[jadex-develop] Inability to use JADEX in Eclipse

[Kenneth A. <ken...@gm...>]

Hi,
I am following the online steps to use JADEX with eclipse to develop a
multi agent system for my project. I installed eclipse successfully and I
also got the recent JADEX release (version: jadex-4.0.177).
After installing eclipse, I unzipped the JADEX version and pointed to its
folder as the folder to point to when creating a new Java project. After
following all procedures as given, I get the following error message during
installation "No Source folder exists in the project".
I have attached a screen shot of the error message.

*Observations:*
1. I observe that the sources file still remains zipped
2. I also observed that the "jadex-example-project" file still remains a
zipped file. I also attached a screen shot of the project files hierarchy
as shown on my computer.

Thanks for your help.

[jadex-develop] Jade and Jadex communication

[anand p. <ana...@gm...>]

I am able to send and receive data between Jadex agents but can't find
anything to communicate with a  JADE agent. Is there anything that can be
used to communicate with a JADE agent (should be FIPA-compliant) ?

Summary: Syntactic Sugar for plans

Initial Comment:
 First of all a big Thank You for this GREAT piece of
software!!!
I would like to propose a little syntactic sugar for
the ADF:
Most of the time I write plans that are triggered by
exactly one goal and use the same parameters with the
same name, e.g.

<querygoal name="classify">
  <parameter class="ExampleSet" name="data" />
  <parameter class="Model" name="model" direction="in">
    <value>$beliefbase.model</value>
  </parameter>
  <parameter class="ExampleSet" name="labeled_data"
    direction="out" />
</querygoal>

<plan name="classify_plan">
  <parameter class="ExampleSet" name="data">
    <goalmapping ref="classify.data" />
  </parameter>
  <parameter class="Model" name="model">
    <goalmapping ref="classify.model" />
  </parameter>
  <parameter class="ExampleSet" name="labeled_data">
    <goalmapping ref="classify.labeled_data" />
  </parameter>
  <body>new ClassifyPlan()</body>
  <trigger>
    <goal ref="classify" />
  </trigger>
</plan>


My proposition is to assume that if a plan has the name
of a goal + the ending "_plan" it is used only for this
goal, therefore will be triggered by it and all goal
parameters are automatically available.
The code above would reduce to

<querygoal name="classify">
  <parameter class="ExampleSet" name="data" />
  <parameter class="Model" name="model" direction="in">
    <value>$beliefbase.model</value>
  </parameter>
  <parameter class="ExampleSet" name="labeled_data"
    direction="out" />
</querygoal>

<plan name="classify_plan">
  <body>new ClassifyPlan()</body>
</plan>


There would be no loss in expressiveness because if
needed you could still provide all mappings, but most
of the time you don't need to.

Thanks a lot for your opinion!

I think this solution is even better :D
We ended up writing a code generator for the ADF to avoid
writing XML like in my first example.
By the way, our code generator is able to produce stubs for
the java plans with all getParameter methods generated. It's
written in Ruby, if you are interested just mail me.

Hi Martin,

thank you for proposing this interesting idea,
which could really help to reduce the perceived
complexity of an adf. One thing that might lead
to difficulties in your appraoch is the implicit
nature of the relationship between the goal and
the plan. What do you think of a new alternative
plan tag such as:

<planforgoal ref="classify">
<body>new ClassifyPlan()</body>
</planforgoal>

Suggestions for nicer tag names are
highly appreciated ;-))

Maybe one would like to have such
short forms also for messages
and internal events?!

We could easily implement such a feature
as it only affects the model and at
runtime there would be no difference
betweeen these kinds of plans.

Would this be a good solution for you?
Regards
Lars

Re: [jadex-develop] setting the position of an agent

[Kai J. <ja...@in...>]

Hello Allaa,

First, please note that you are technically dealing with two different
things: a) the agent which only uses positional information if it
requires it and b) its representation in the environment (avatar, or
space object) which necessarily requires a position.

I'm assuming you are trying to set the initial location of a space
object (which may or may not have an agent associated with it). You can
simply do so in the application XML:

<env:property name="position" event="true">new Vector2Double(2.0, 2.0)
</env:property>

Alternatively, if you want to change the object position at runtime,
you can do so with the code you proposed but you have to initialize the
vector with the position you want:

((Space2D)space).setPosition(obj.getId(), new Vector2Double(2.0, 2.0));

Note that the position gets adjusted to fit into the environment, so if
your environment is only 1.5 wide, the X value would either be clamped
at 1.0 or, if the environment wraps, adjusted to 0.5.

I hope this helps.

With kind regards
Kai Jander

[jadex-develop] Cannot reference nonstatic field of null value: <SFipa.CONTENT>, null

[Luigi M. G. <lui...@gm...>]

Hi to all,
I'm doing this Jadex BDI tutorial:
http://jadex-agents.informatik.uni-hamburg.de/xwiki/bin/view/BDI+Tutorial/03+Using+Plans
and at the Exercise B4 (Plan Selection)
I had this RuntimeException: java.lang.RuntimeException: Cannot
reference nonstatic field of null value: <SFipa.CONTENT>, null when I
send a message to the Agent by the Conversation Center.

I think that the problem is in the ADF xml file, more specific in the
precondition statement:

	  <precondition>
    		EnglishGermanTranslationPlanB4.containsWord((String)Event.getParameter(SFipa.CONTENT).getValue())
  	  </precondition>

Can someone help me? Thanks a lot.

Luigi

PS: Is there any other newer tutorial on BDI kernel?

Re: [jadex-develop] Can you help me solve my ploblem?!

[Alexander P. <po...@in...>]

Dear Behrooz Dalvandi,

this problem probably comes from an incompatibility between Jadex 0.96 and
Java 1.6 (or later). Try switching to the newer Jadex 2.0-rc1 or use an 
older
Java JDK available from here:
http://java.sun.com/javase/downloads/index_jdk5.jsp

Kind regards,
Alex

[jadex-develop] Can you help me solve my ploblem?!

[behrooz d. <beh...@gm...>]

I am a new master student in University of Northern British
Columbia<http://www.unbc.ca/>and I am supposed to implement somethings
through Jadex.
I have downloaded the standalone version (0.96) and I could run it until 2
days ago by this command: "java -jar /lib/jadex_standalone.jar"

But after I installed the NetBeans IDE, when I want to run Jadex, I face
this error message:

[jadex-develop] New Jadex version

[Alexander P. <po...@in...>]

Dear Jadex Users,

a new version of the Jadex BDI agent framework is available.
This version V2 beta 3 can be downloaded from sourceforge as usual
by following this link:

http://sourceforge.net/project/downloading.php?group_id=80240&filename=jadex-2.0-beta3.zip&a=99250434

The new version contains among others the following interesting new
functionalities:

- New application descriptor XML for defining whole agent applications.
This allows you to declare what the components of an application are at
one central place.
- Generic environment support. This new infrastructure component can be used
to easily create 2D simulation applications without needing to write
(much) implementation code for the environment and its visualization.
- All Jadex simulation examples (like Hunterprey and Garbagecollector)
have been rewritten to use this new generic environment support.
- Jadex V1 Java condition language (JCL) support. This means that it is
not necessary any longer to use the rather complicated CLIPS notation for
conditions but they can be formulated as in earlier releases.

Kind regards,
Lars Braubach

[jadex-develop] Jadex V2 beta1 available

[Lars B. <bra...@in...>]

Dear Jadex users,

after a long development time (1,5 years) we are happy to announce
that a completely new version of the Jadex BDI reasoning engine is
available. This new version of Jadex (called V2) is a complete overhaul
of the first version. The BDI architecture is now realized as rules on
top of a standard rule engine. Furthermore, the execution environment
now allows the execution of arbitrary agent architectures . As an examples
a minimal micro agent architecture has been additionally provided.
Independently from the type of the agents, applications can now be executed
in realtime (as usual) as well as in simulation modes (event- and time 
driven)
without requiring changes to the agent's code. A short list of new features
is provided below:

Release 2.0 beta1 (V2 Beta-Release 12/2008)
   - Complete rebuilt of the BDI-kernel, on based on a rule engine
   - Exchangeable agent kernels for different agent architectures
   - New micro agent kernel (minimal features for minimal resources)
   - Initial simulation support allowing event- and time-driven 
simulation runs
   - Restructured service-based standalone platform
   - Multiple platforms can be started in the same Java VM
   - New comanalyzer tool for observing message exchanges
   - New library service for managing the classpath at runtime via the JCC
   - New examples (alarmclock, watchdog)
   - Enhanced platform and agent efficiency

Re: [jadex-develop] Mistake in documentation ?

[Guillaume V. <gui...@va...>]

Hi Lars,

You are right, MY mistake was that I didn't respect the correct order of 
tags inside the agent :
name="imports"
name="capabilities"
name="beliefs"
name="goals"
name="plans"
name="events"
name="expressions"
name="properties"
name="configurations"

Sorry ...

Kind regards.

Re: [jadex-develop] Mistake in documentation ?

[Lars B. <bra...@in...>]

Hi Guillaume,

this is not a bug in the documentation as there are two places where
you can put the <properties> tag (see schema). Inside the agent and
also as top level element (necessary for property file).

Kind regards,
Lars

[jadex-develop] Mistake in documentation ?

[Guillaume V. <gui...@va...>]

Hello everybody,

I belief that there is a mistake in jadex adapter documentation :
http://vsis-www.informatik.uni-hamburg.de/projects/jadex/jadex-0.96x/userguide/adapters.html

According to the schema http://jadex.sourceforge.net/jadex-0.96.xsd , 
the position of the <properties> tag should be :
<agent ...>
     ...
</agent>
...
<properties>
   <!-- Setup a filter for messages which are handled by JADE 
behaviours. -->
   <property name="jadefilter">
     MessageTemplate.MatchPerformative(ACLMessage.QUERY_REF)
   </property>
</properties>

instead of :

<agent ...>
     ...
     <properties>
         <!-- Setup a filter for messages which are handled by JADE 
behaviours. -->
         <property name="jadefilter">
             MessageTemplate.MatchPerformative(ACLMessage.QUERY_REF)
         </property>
      </properties>
     ...
</agent>

Re: [jadex-develop] jade adapter for connect-disconnect-reconnect

[Alexander P. <po...@in...>]

Hi Robert,

JADE uses RMI (Java's Remote Method Invocation protocols) to connect
the distributed containers to a platform's main container.
I can only guess, that these protocols do not like being disconnected
and reconnected. If you specifically want to support network outages
(e.g. as part of your application scenario), I would recommend to
opt for a more loosely coupled approach. E.g. you could start separate
platforms on the different hosts and let the agents communicate over
some message transport protocol such as the HTTP MTP.

You might also consider asking your question on the JADE list,
as the communication between containers is specific to JADE.
Maybe the JADE developers know the reason for your problems
and can suggest a simple solution.

Cheers,
Alex

> Has anyone attempted to use the jade adapter to connect multiple agents together that reside on different computers?  I'm testing my jade-jadex communications to see if I can successfully connect, disconnect, and reconnect my agents.  My test consists of three desktop computers on the same domain.  Computer 1 and 2 connect to computer 3 which contains the main-container.  As long as I bring up the main-container on computer 3 first the other two computers are fine.  However, if I disconnect the cat5 cable on computer 1 or 2 for six seconds or more and reconnect, computer 3's jcc realizes that the connection was broken and then displays a re-connect container message, however computer 1 or 2 no longer receives message events from agent3 that runs on the same host as the jcc and there is no evidence of a problem in agent1 and agent2's display output.

I should also note that the network card LEDs on computers 1 and 2 continued to flash yellow again after the cat5 cable was reconnected indicating that agent3 messages continued to arrive at computers 1 and 2 although agents 1 and 2 respectively are not receiving a message event. Below is a listing of my batch files.
