Package: Jeas: Java Enhanced Availability Server
System name: jeas
Type: 2

Description:
Java Enhanced Availability Server
is a parallelised web server written in Java.

It purposes a load balanced, fault-tolerent, high availability http server, 
bases on the LVS model:

-1 Traffic Manager with his backup
-X Real Servers
-1 Data Server with his backup

The Traffic Manager redirect requests on Real Servers depending of their 
current load (the less loaded get it).

Real Servers analyse the requests and elaborate an appropriate HTTP/1.1 
compliant response before send it to the client.

The web content and datas are stored on the Data Server, not on the Real 
Servers.Though Real Servers access datas via the Data Server.

Both Backup servers are exact clones of their primary server.
An hearthbeat system permits to detect a primary server crash ; if it happens 
the backup server transparently substitute to the primary server by using ARP 
Poisoning (also knew as ARP Spoofing or Gratuitous ARP).
When the primary server come back to life, the backup server detects it and 
stops to send ARP Echo Replies.



All this features are massively unsing RMI APIs.


There is no official release right now but I am working on it.


Other Software Required:
It only requires a Java VM : http://www.kaffe.org
