Abstract: With the popularization of e-learning, various teaching software, tools and e-learning platforms unceasingly appear. In order to solve the problems faced while integrating the heterogeneous e-learning systems, such as the heterogeneity, the interoperation and the scalability, an integrated framework for e-learning systems based on J2EE (IFESJ) is proposed. IFESJ peels off the common services from the heterogeneous e-learning systems and integrates them to support the teaching activities based on the network from aspects of the portal, the service and the data. The practical application and the testing results on the performance indicate that the design of IFESJ is reasonable and the e-learning system based on IFESJ can satisfy the concurrency requirements in practice.
