This　paper　analyzes　the　architectures　of　JADE　and　J2EE:　J2EE　advances　in　developing　enterprise-class　applications,　but　it　doesn＇t　support　Agent-oriented　programming　JADE　is　suitable　as　a　MAS　development　framework,　but　it　considers　less　in　maintainability,　expansibility　and　stability.　According　to　these,　this　paper　proposes　a　MAS　model　-　JadeEE　(Java　Agent　Development　Framework　Enterprise　Extension)　-　which　is　based　on　JADE　and　J2EE.　This　model　is　an　enterprise-class　MAS　application　development　framework　which　advances　in　stability,　easily　expansibility　and　maintainability.　It　is　suitable　for　large-scale　MAS　development,　has　the　same　advantages　as　J2EE　and　keeps　enterprise-class　MAS　running　at　an　acceptable　speed.　This　framework　has　been　used　in　the　development　of　GDSS　(Group　Decision　Support　System)　for　typhoon　comprehensive　forecast　effectively.
