....can be extended and customized to change some output behavior, so that graphical information can be displayed on runtime. 17 5 Other Relevant Agent Systems In this section we described some relevant systems that do not emphasize mobile agents. There are a lot of agent systems such as JAFMAS [3], Bond [2] Decaf [4] etc. All developed in Java. We are going to focus on JatLite for being based on the rst agent system developed in Java, Jat, and because it uses the standard KQML language (Knowledge Query and Manipulation Language) 9] We are also going to focus on Voyager for being a ....

....most of them implement a specific agent system. The user of these systems is expected to download the provided software and build his agents as extensions to the system. Sometimes these architectures take the form of software libraries that the user can link to, such as JATLite[16] and JAFMAS [8], other times they provide graphical user interfaces which the user is expected to use for building his agents, such as ZEUS [19] As such, these agent architectures provide a finished product which commits the user to a specific structure, a specific language, and a specific set of limitations. ....

....the coherency of the entire system can be proven. The Java based Agent Framework for Multi Agent Systems (JAFMAS) uses an approach as part of it s multi agent system design methodology, that allows one to show that a given set of conversations in the system are consistent and coherent. The JAFMAS (Chauhan 1997) methodology uses automata models to specify conversations, which can then be converted into a Petri net representation to analyze for system consistency and coherency. In current work at the University of Cincinnati, the JAFMAS Development Environment (JAFMAS DE) Galan) automates the JAFMAS ....

While synchronous communication corresponds to traditional Java method invocation, the other types of messages can be delivered by objects by invoking specific Voyager methods. Other systems, like JAFMAS [15] and JATLite [1] would allow our agents to be distributed on a network and communicate in a standard agent communication language based on Speech Acts [38, 20, 30] However, following KQML, they impose that the contents of the speech acts are represented, in an appropriate content language, as ....

Making shared conventions explicit allows interdependencies among agents activities to be managed. Apart from COOL, other agent building tools such as AgentTalk[1] or JAFMAS [7] also provide coordination constructs. JAFMAS , for instance, provides a generic methodology for developing speech act based multi agent systems using coordination constructs similar to COOL. However, many more agent building tools that have not addressed this issue yet 2 . Interagents like ....

This capability of allowing agents to define and modify themselves their conversation protocols at run time happens to be an innovative feature of our proposal, distinguishing interagents from other approaches like COOL[6] or JAFMAS[7]. 5 Applications JIM our Java based implementation of a generalpurpose interagent, is being used as the communication and coordination support for the agents developed in the framework of the SMASH project.

Agents have been successfully used as the building blocks for business application infrastructures [13] Many agent models use KQML [12, 22] for interaction and communication, e.g. IBM Aglets [24, 30, 23] Jackal [4] or JAFMAS [7]. However, these models and their implementations often lack a model for contents being transferred between agents. Instead they hold a knowlege base to support dynamic decision making. We believe that having a content model is a necessity for supporting business objects in information systems. ....

The resulting system can then be tailored to a specific agent system style, such as used in JAFMAS (Chauhan 1997) where agents are generated in Java and use specific low level communications structures to carry out high level agent conversations.
