本文介绍了一种基于包的Java软件架构设计方案，详细说明了不同包的功能定位：如constants包用于存放公共类及常量，core包包含核心业务类并定义接口以供实现，data包负责数据库管理包括JavaBeans定义等，exception包自定义异常处理，jsp包分离JSP页面的业务逻辑。

package constants: all public classes, fileds in which is public static final, CONSTANT

package core: commonly used classes, always contains a interface(like class Service, Message and so on) and classes implement it.

package data: DB Management, including Java Beans for DB. In which, class DataSet defines the data from DB(including fileds col_name, row_data and dataset_name). DBManage manages the DB connection.

package exception: custom exceptions

package jsp: functions seperated from JSP. Inteface Command and interface ContentModel(javabean)。The classed implementing former interface usually have excute function to return object of the latter type.
