The architecture of traditional Ecommerce systems is usually aptotic, which consist of several fixed servers to offer particular services; obviously, the security and robustness of the system are undermined under such circumstances. Meanwhile, the form of trade is always the same; traders can not discuss and negotiate  the price, discount, and trade time of commodities simultaneusly and at anytime in order to trade efficiently. To solve the problems, a multiagentbased distributed intelligent Ecommerce system is introduced. We utilize the multiagent technology to realize a distributed and intelligent business system. In our system, the inquiry, negotiation and trading are all executed by agents automatically. In the end, we use the JADE platform to build the system to prove the feasibility of our solution.
