Work Done:
System was developed for a Maltese company. System allows merchants send the invoices to customers. Also it allows customers receive and pay the invoices with the help of Java-application installed to the cell phone. As a tool of payment Visa and Master Card are used.
How the System works.
Merchant sends an invoice to the customer through web-terminal.
Invoice is received by the processing center of our partner.
Processing center sends the customer an SMS with notification, that there is a new invoice received.
Having received the SMS, customer launches Java-application on his cell phone and confirm his willingness to pay the invoice.
Confirmation of the invoice payment goes to the server.
Our partner's system connects VISA/MC processing center and makes an
electronic transaction, transferring the money from the customer's card account to the merchant's one.
System Architecture:
The base of this system is three-layered architecture (Web-layer, application logics layer and data layer), realized on the basis of J2EE.
FireWall – filters incoming traffic, provides defense from DDos attacks.
Web Cluster – provides processing of HTTP requests, which are sent by merchants and customers` Java-applications on the cell phones. As a WEB-server Apache-Tomcat is used. Each server in the web-cluster has 2 network interfaces. Thus there is no access to data base servers and applications from Internet, which makes the system very safe.
DMZ – Internal network of the system, which includes application servers and databases.
Hardware Switch – internal network switch.
APP Cluster – application servers cluster. As an application server JBOSS is used.
DB Server – servers of Oracle database working in the Stand-by mode.
Technologies: Java(J2EE, J2ME) Oracle |
