Development, Based On The J2ee "digital Map Production Management System," The Practice

This paper references on the application bound of the workflow and workflow manager system to design and develop "Digital Map Production Manage System" .The architecture of this system according to the main technique of the platform of J2EE, and import the Java's software development kit which very popular currently to implement the main expectation function of this system, through the practice to obtain the satisfied results. This paper point introduced the application of workflow technique and J2EE system architecture through the practice of this system, careful studied the design and development of GIS function module,Enterprise JavaBean, about the database table object of persistence etc.function module carries on development and fulfillment.The basic contents of this paper include:1 , Introdued the definition of workflow and workflow manage system. Surround four arrangements which the J2EE defined: The customer tier, the Web tier, the business tier and the enterprise information system tier, introducing abundant technique and standard which it defined.These techniques covered JavaBean technique, Servlet technique, EJB technique and Database Access etc.2, Introduced the structure of DMPMS,and introduced to a point the designs way of thinking of this system's GIS function module which have finished, give the Rose design diagram of a main function module and the design of the space database table structure, in additon ,carry on the introduction for the some and main functions of GIS.3, Surround the realization of this system's MIS function, play the emphasis on the studied the J2EE application server-JBoss installs and usage, the design and development of Enterprise JavaBean, the deployment of this system and so on contents.At the same time,import the efficient ORM tool Hibernate2 and statistical charts of JFreeChart go into develop , introduc the application in the system development.
