Java
Java technology, created by Sun Microsystems, offers many benefits to Internet and application programmers. The JDK (Java Development Kit) enables developers to:

• Write software on one platform and run it on another.
• Create programs to run within a web browser.
• Develop server-side applications for online forums, stores, polls, processing HTML forms, and more.

There are several versions of the JDK that can be installed, or are already installed, on your Virtual Private Server. The JDK contains the Java compiler and Java executable, as well as the bulk of the standard Java libraries.

Installation
To install the JDK 2, do the following, depending on your Virtual Private Server O/S.

• FreeBSD [Java 1.2.2]
  You must install this yourself. Installation is not supported. See the following for more information.

  • FreeBSD Java Project: JDK 2

• Solaris [Java 1.3.1.01]
  To install JDK 2, connect to your Virtual Private Servers via Telnet or SSH and execute this command.

  % vinstall j2sdk

• BSD/OS Upgrade!
  JDK 2 is not available. Try JDK 1.1.

Java Servlets and JSPs
Java Servlets and JSP (JavaServer Pages) technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server. A servlet can almost be thought of as an applet that runs on the server side. JSP is a server-side technology that is an extension to the Java Servlet technology. JSPs have dynamic scripting capabililty that works in tandem with HTML code, separating the page logic from the static elements.
