Java and the Internet
The Java platform is highly regarded in networking because of its suitability for writing programs that use and interact with the resources on the Internet ( World Wide Web) in a secure way.
Java provide Applet through which we can make an application which can run under Java-compatible browsers and transfer data from local machine to server through internet in secure way.
Any information transmitted over computer networks or through Internet must be secure .It become more important when we are transferring most sensitive informationís like credit card numbers and other personal data. To make the Internet more useful in an enterprise and more secure for e-commerce, applications and e-business applications .And their users' information, using encryption, authentication, and secure communications protocols.
The secure Hypertext Transfer Protocol (HTTPS), which is HTTP over the Secure Sockets Layer (SSL), is already being used successfully for e-commerce applications for security purpose. Java programming language provides a JSSE API .The Java Secure Socket Extension (JSSE) is a set of Java packages that enable secure Internet communications.
It is a framework and 100% Pure Java implementation of the Secure Socket Layer (SSL). These packages enable developer to develop secure network applications which communicate to server .Which use secure data passage of data between a client and a server running any application protocol ( HTTP, FTP, Telnet, or NTTP, over TCP/IP).
Java also provides J2EE to develop an enterprise application for internet.J2EE contains so many components like Java Sever Pages, Sevlets, EJB JMS etc through which a Java Developer can make an interactive, secure web base java applications.
