E-Accountant System Overview
Brief Description
The E-Accountant System enables the banks to reduce their unnecessary manual work while providing remote services and on-line management. It also enables the bank to serve as long as 24 hours and will definitely increase the efficiency.

Software Pattern
Brief Description
We use the observer pattern to design our system.
We divide the system into three layers. They are view layer, control layer and model layer, which is the classical structure of MVC architecture.

MVC Architecture Pattern
Presentation Layer
V
We put all the swing graphical presentation components and JSP files in this layer when designing the windows forms and the web pages.
C
We design an abstract controller class to play the control role in this program, which is heritaged by a class named buttonctrl.In JSP, we make JavaBean functions in this layer.
Logic Layer
M
Data Layer
In this layer, we design a class connecting to dataservice, which can modify the database and notify all the views.

Using XML to Store
Data
XML Serialization
Details We use a middle library called XStream to serialize objects
to XML and back again. Here our projects coding:public class User extends UserI
{
protected String UserName;
protected int ID;
protected double account=0;
protected static double credit=5000;
protected MainCard mc=null;
……
}
When it serialize to XML, it can be shown:
demo.xml
back
Web Server
Details
Using JSP to design the presentation layer of the program.
Using JavaBean to control the business handlers.
Using tomcat 5.5 to configure the server Using Lomboz to edit the jsp files. Using session to confirm that these web pages
can not be visited unless the user has log in.
back
RMI
Details
We use RMI to connect POS and Server, E-Account Bank System and Server.
IAccountModel a = new RAccountModel(); IConsumeModel c =new RConsumeModel(); LocateRegistry.createRegistry(1099); Naming.rebind("rmi://localhost:1099/Service", a);
Naming.rebind("rmi://localhost:1099/Service2", c);
IAccountModel is the bank system remote interfaceIConsumeModel is the POS remote interface
In the client,we make the model class to use these interface.
back
JAVA MAIL
Details
we using the javamail api which can be found in J2EE to write a Mail Client. It can connect to some SMTP Server Provider and send mail to anyone else's mail box.
In this project, once the client apply or revoke a sub-card, change the card password, we'll send the email to notify him these changes. On the 25th day of every month, we will send the bills to every account by email.
