To realize the efficient integration for new and old system in enterprise is the purpose of this paper, and provides a enterprise application integration framework based on Web Services and J2EE in order to solve the information "isolate island" problem efficiently.First of all, the concepts of enterprise application integration, Web Services and Java techniques are introduced in this paper. Second, it explains the relationships between enterprise application integration and Web Services and the advantages of the integration of them. Third, J2EE and the techniques relate with it are introduced, discuss the EJB and the relationship between J2EE and Web Services. At last, a framework is designed based on Web Services and J2EE, and realized the enterprise application integration between new and old systems in the simplest way.
