The Design And Implementation Of Material System Based On J2EE

With the rapid development and wide application of the Internet/Intranettechnique, the application based on the Wed pattern is more and moreprevalent. It will be very convenient for system installation, update,maintenance, and data backup that explore post material system according tothe J2EE pattern.There are many advantages in loping application based on J2EE patterncompared with the traditional C/S approach..1.non-equipment on the client-side It is adopted B/S structurecompletely in material communication system. It may not install anyapplication program. The user may do any service treatment inInternet/Intranet with the computer having browser.2.no-related characteristic of operating system The operatingsystem is developed in pure Java technique. The material information systemhas excellent identity in multi-flat implement with the no-related in mac os. Itrealized a development everywhere.3.high applied expandability In the system developing, it is adoptedSpring and Ibatis frame, decreasing some coding work. It is convenient inexpanding the application system with the module designed.4. saving investment It uses server with free Tomcat 4.1.30. Andthe client machine may not set applied program. Thus, it has a lower demandin Primary Frequency, EMS memory, hard disk.5. easy maintenance The data is memorized assembly. And it iseasy to backup.More than 10 systems software have been used in the process ofdeveloping material managing system. The emphases of this thesis are thecomprehensive instruction on the characteristic, advantage and the installingconfigure of Tomcat, Rose, CVS, Spring, iBatis.The applied development is very different using Spring/iBatis framebased on J2EE pattern from the traditional J2EE MVC pattern. It issimplified in the representation layer, controlling layer, operational layer andpermanent layer. The function will be increase, too. In spite that it needsmuch more energy to grasp initially, there are obvious effects using this kindof frame. In this article, there are 16 sorts of interface and implementing anddeploying documents, which were illuminated and demonstrated with code inrespectively.Modeling technique is very useful in the process of system development.The function of the pattern is to simplify the complicated information. Wecomplete the analysis and design on the material system operational pattern,system pattern, logical pattern using Rational ROSE modeling tool. It candefine the operational demand described in natural language accurately withUML chart. It also try to define the method of classification and property inthe program.Two functions will be implement on scheming management and in-outmanagement for materials after analyzing and settling the demand putforward by the department of post materials. The system can declare, collectand verify on province-city-county through the management. It also canadjust scheme and generate order form automatically. The 14 in-out proofoperation voucher are redesigned in providing materials management inaccordance of the work process following online operations in the provincialnetwork. Four kinds of operator proves needed to be created manually byoperators are remained. They are fetching document,invoice,returndocument and consignment returning document。The others are createdautomatically in system according to the different station. These four provescan also be transformed from scheming proof, order proof or the relatedproves of higher and lower departments. They are furthest convenient forregisters. It can create 10 operations voucher automatically throughrecreating operation workflow. That will be very convenient for the registers.The stork account books include the account for future reference registeredon in-out goods actually and the account list financial registered conformingto the information of balance. All of them are registered automatically,proving multiple kinds of auditing. Recently, with the condition of hand work,it is hard to translate materials administered unitedly into action in all theprovince completely. And each department is absent of effective method insupervising and administering. Using this system may solve this problem ingrain.
