摘要： 随着新的应用形式以及应用环境的改变，中间件不仅要解决异构和分布情况下的复杂问题，而且要解决动态性和灵活性，由此产生反射中间件。目前，基于J2EE 架构的反射中间件没有解决网络的QoS 控制问题。该文设计了一个提供QoS 控制的反射中间件的原型（HHRM），先从重配置的角度对该原型进行了深入的分析，然后比较了它和主流反射中间件之间的重配置机制的差别。

Abstract: With the appearance of new application form, middleware needs not only address the issues of complexity and heterogeneity inherent in distributed systems, but also to manage dynamic and flexibility. Thus, reflective middleware considered to resolve the problem becomes one of the hot topics in the research on next generation middleware. But, reflective middleware based on J2EE can not provides QoS (Quality of Service) control, This paper presents a model (HHRM) and implements it. The paper analyzes the reconfiguration mechanism of HHRM, and compares it with other reflective middleware’s mechanisms.
