Using the Virtual Machine

Chapter 4 Managing Your Snap Server 31

Using the Virtual Machine

Your Snap Server comes with a virtual machine already installed. This lets

applications based on Java™ technology run on the Snap Server. The virtual

machine is a software module that converts the platform independent code based

on Java technology into code that is specific to the Snap Server’s microprocessor.

Once the code is converted, the virtual machine executes the converted code.

What is a SnapExtension?

A SnapExtension is an application designed to run on the Snap Server.

SnapExtensions are integrated using the framework created specially for them. The

Snap Server framework allows you to access an application based on Java

technology from the Snap Server Web Administration Tool. Only applications

developed and integrated for the Snap Server can be accessed this way.

You can find installed SnapExtensions on the SnapExtension page; open the main

page of the Web Administration Tool and click

SnapExtensions.

Check the Snap Appliance Web site at http://www.snapappliance.com

for other

available SnapExtensions.

Enabling the Virtual Machine

By default, the virtual machine is turned off. To turn it on and begin using

SnapExtensions and other applications based on Java technology:

1 Start the Snap Server Web Administration Tool and click SnapExtensions.

2 Click Start Java to start the virtual machine. You are then prompted to confirm

that you want to start Java.

3 Click Yes to restart the Snap Server with the virtual machine enabled.

What is Secure Server?

Secure Server uses Secure Sockets Layer (SSL) to let you transmit private data over

TCP/IP. The data is encrypted using a private key prior to transmitting the data. By

encrypting the data prior to transmission, it will be secure and can only be read by

the user requesting the data via a web browser. The secure server is supported by

all major browsers. To access the Snap Server using SSL, the Uniform Resource

Locator (URL) will begin with https: instead of http:
