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 Server. The JDK contains
the Java compiler and Java executable, as well as the bulk of the
standard Java libraries.
JDK 2
Do the following, depending on your Virtual Server O/S.
-
FreeBSD Java 1.2.2
You must install this yourself. Installation is not supported. See the following for more information.
-
Solaris Java 1.3.0
To install JDK 2, connect to your Virtual Server via Telnet or SSH
and execute this command.
% vinstall j2sdk
-
BSD/OS Upgrade!
JDK 2 is not available. Try JDK 1.1 (below).

Huh?
If you don't know the Virtual Server O/S, try the following:
JDK 1.1
Do the following, depending on your Virtual Server O/S.
-
FreeBSD Java 1.1.8 (java_X 1.1.8)
JDK 1.1 is already installed. The compiler and virtual machine can be run
using these commands:
% javac
% java
-
Solaris (Java 1.1.8)
To install JDK 1.1 (Java 1.1.8) , connect to your Virtual Server via Telnet or SSH
and execute this command.
% vinstall jdk1.1.8
-
BSD/OS Upgrade!
JDK 1.1 (Java 1.1.2 and kaffe 0.91) is already installed. The compiler and virtual machine can be run
using these commands:
% javac
% java1.1
-
Huh?
If you don't know the Virtual Server O/S, try the following:
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--the actual design and display of the page.
