%X This paper presented the deficiencies of several common dynamic load balance algorithms and many of the main J2EE(Java 2 enterprise edition)application servers hadn't selfadaptive dynamic load balance.Using the Open Source JBoss as the developing platform and some of design pattems,this paper designed a model of self-adaptive dynamic load balance services.Centring on load indexes,load collection and balance algorithms,this paper came up with a new idea of alternating load collection based on update_time attribute,and realized a self-adaptive dynamic algorithm of relative load balance degree based on first K subset.The test results show this algorithm can balance the system loads betterly.
