Abstract
Agent has been getting popular these years. Implementing an agent platform is based on the supporting language and underline 00 library. Currently, the most popular Internet language is JAVA and the library for Internet related software is JDKI.2. We designed and implemented an agent platform based on JAVA and JDKI.2. In this paper we present our design architecture of agent platform with UML and discuss a series of problems related to agent and platform. We also give some discussions and our (partial) solution for each problem in our system.
