Java
Java is a programming language developed by
Sun Microsystems which offers developers the ability to write
platform-independent programs. One of the biggest advantages to the platform independent approach
to programming is that programs can run as applets in a client's browser, rather than having
to run on the server.
Java1 is available as a default program on your VPS and can be found in the /usr/local/bin
directory on your server.
Installing Java2
Due to the nature of the Java2 license, there are several steps that you must go through in order
to install Java on your VPS.
- Dowload the J2SDK version 1.3.1 from
http://www.sun.com/software/opensource/index.jsp.
You will be required to register with Sun before downloading the J2SDK. Once you have downloaded the file,
save it on your VPS in the /var/distfiles/ directory (you may need to make the directory first).
- Download the Linux JDK from
http://javadl.sun.com/webapps/download/
and copy it into the /var/distfiles/ directory of your VPS
- Download the BSD patch for the JSDK from http://www.eyesbeyond.com/freebsddom/java/jdk13.html
and install it in the /var/distfiles/ directory of your VPS.
- Once both the files have been placed in the /var/distfiles directory, install java by running the
following commands as root from your VPS shell prompt.
# cd /ports/java/jdk13
# make
It will take several minutes for make to build and install Java and all the dependencies.
In order for your Java programs to find the Java compiler, you will need to indicate the full path to
java in the program, or add the path to your shell's PATH.
