Sixearch: Social Web search via adaptive peers

Java Run Time Environment

Part 1: Java Version

Background

The first requirement to run Sixearch application is that your computer has a Java run-time environment installed. This is commonly referred to as a Java Virtual Machine or JVM. This page can teach you how to verify whether your computer is capable of running Java applications. If your computer is capable, then you can also use this information to see which version of the Java run time environment (JVM) your computer is using, something that is much harder to do than it should be. Java Virtual Machines are available from a number of software companies, but Sixearch application are best off with one from Sun Microsystems.


Method 1: Ask Sun Microsystems Inc.

This is the simplest approach to verify your Java Virtual Machine (JVM). Just click here.


Method 2: Command line checking

In Windows, open a DOS prompt (Win + R type cmd click OK). In Mac OS X  or Linux, open a terminal.

Enter the following command

   java -version 

The output will look something like:

 java version "1.6.0_02"
 Java(TM) SE Runtime Environment (build 1.6.0_02-b06)
 Java HotSpot(TM) Client VM (build 1.6.0_02-b06, mixed mode, sharing)

You can also use "java -fullversion" and produce output such as:

 java full version "build 1.6.0_02-b06"


Method 3: The Java system tray icon

In Windows, if the Java coffee cup is displayed in the System Tray you can right click on it, select "About Java Technology" and get a display that looks like the one shown here.


Part 2: Install or upgrade Java

Follow the link below for downloading and installing the Sun JVM:

www.java.com/en/download/manual.jsp

If your current version of Java is not the latest, we suggest un-installing your current version, then downloading the manually installable version (link above) and using that to install the new version.

For Mac OS X 10.4, please use the Software Update feature (available on the Apple menu) to get the most up-to-date version for your Mac.
