JADE Programmer’s GUIDE

Ontology and all the classes representing its concepts. The subpackage jade.domain.introspection
contains the concepts used for the domain of discourse between the JADE tools (e.g. the Sniffer
and the Introspector) and the JADE kernel. The subpackage jade.domain.mobility contains all
concepts used to communicate about mobility.
The
jade.gui package contains a set of generic classes useful to create GUIs to display and
edit Agent-Identifiers, Agent Descriptions, ACLMessages, …
The
jade.mtp package contains a Java interface that every Message Transport Protocol
should implement in order to be readily integrated with the JADE framework, and the
implementation of a set of these protocols.
jade.proto is the package that contains classes to model standard interaction protocols
(i.e. fipa-request, fipa-query, fipa-contract-net, fipa-subscribe and soon others defined by FIPA),
as well as classes to help application programmers to create protocols of their own.
The
FIPA package contains the IDL module defined by FIPA for IIOP-based message
transport.
Finally, the
jade.wrapper package provides wrappers of the JADE higher-level
functionalities that allows the usage of JADE as a library, where external Java applications launch
JADE agents and agent containers (see also section 3.8).
JADE comes bundled with some tools that simplify platform administration and application
development. Each tool is contained in a separate sub-package of
jade.tools. Currently, the
following tools are available:
¾ Remote Management Agent, RMA for short, acting as a graphical console for platform
management and control. A first instance of an RMA can be started with a command
line option ("-gui") , but then more than one GUI can be activated. JADE maintains
coherence among multiple RMAs by simply multicasting events to all of them.
Moreover, the RMA console is able to start other JADE tools.
¾ The Dummy Agent is a monitoring and debugging tool, made of a graphical user
interface and an underlying JADE agent. Using the GUI it is possible to compose
ACL messages and send them to other agents; it is also possible to display the list of
all the ACL messages sent or received, completed with timestamp information in
order to allow agent conversation recording and rehearsal.
¾ The Sniffer is an agent that can intercept ACL messages while they are in flight, and
displays them graphically using a notation similar to UML sequence diagrams. It is
useful for debugging your agent societies by observing how they exchange ACL
messages.
¾ The Introspector is an agent that allows to monitor the life cycle of an agent, its
exchanged ACL messages and the behaviours in execution.
¾ The DF GUI is a complete graphical user interface that is used by the default
Directory Facilitator (DF) of JADE and that can also be used by every other DF that
the user might need. In such a way, the user might create a complex network of
domains and sub-domains of yellow pages. This GUI allows in a simple and intuitive
way to control the knowledge base of a DF, to federate a DF with other DF's, and to
remotely control (register/deregister/modify/search) the knowledge base of the parent
DF's and also the children DF's (implementing the network of domains and sub-
domains).
¾ The LogManagerAgent is an agent that allows setting at runtime logging information,
such as the log level, for both JADE and application specific classes that use Java
Logging.
