This paper reviews the development of Web applications in the Java programming language, namely the creation of a Web application through three-layer architecture using Java Servlet technology and Java Server Pages (JSP). This paper shows the development of Web applications in the Java programming language. Web applications are used in order to respond to the user’s requests, i.e. generate Web pages on the client's request. The applications are stored on the server and operate on the principle of client-server connection, i.e. client sends a server request, when the server fulfils the request, it sends a response to the client. The advantages that we specified in this paper are the development of web applications applying Java technology. Motivated by the current popularity of this technology, our aim was to introduce a way of developing web applications that will become a trend in the future. Primary goal of this paper is to present the most appropriate methods of developing web applications. Conclusions from our study are that the Java is programming language with exceptional opportunities when it comes to web development in terms of simplicity of implementation and speed of execution of the final product.

J2EE architecture has many complicated layers, including client. These layers are presentation layer, business logic layer and data persistence layer. There is respective data presentation in relevant layer of J2EE, with strictly rules to access and transform data objects between these layers. This paper brings forward middleware technology which is the kernel and key to the solution of the dynamic E-business system through analyzing J2EE architecture and the most important MVC (Model View Controller) design pattern. It includes the component technology of JSP, Servlet and EJB etc. J2EE technology and MVC design pattern can simplify the software development, improve the software performance and quickly construct the dynamic E-business system of the good expansibility, maintainability, dependability and high usability. The traditional system of industry report is highly influenced by the database security and has low efficiency on report. In order to solve these problems, this paper studies J2EE and MVC architecture, combine them and propose an industry report system which based on J2EE and MVC architecture. The system which makes full advantages of both architecture, has solved the problems such as avoid showing databases pattern to client directly and separating the data persistence layer, business logic layer and presentation layer from each other. It obtains a good result in the web based practical application.

Smart dust is a system of many tiny Micro Electro-mechanical systems (MEMS) such as sensors, robots, or other devices, that can detect, for example, light temperature, vibration, magnetism, or chemicals. They are usually operated on a computer network wirelessly and are distributed over some area to perform tasks, usually sensing through radio-frequency identification. Without an antenna of much greater size the range of tiny smart dust communication devices is measured in a few milli-meters.
