... and, JavaScript is a darn cool language!
So, what options do youhave?
There are two mainplayers...

Some Other SSJS Projects...
App JetRecently announced and launched SSJS
solution.
Looks promising, but appears to be somewhat limited at the moment. Has some nice APIs tho, worth a
look!www.appjet.com
PhobosProject Phobos is a lightweight,
scripting-friendly, web application environment running on the Java
platform.
More of a framework, and actually runs on Rhino. Still considered experimental, but a good project
nonetheless.

Right,
Let’s take a look at some examples...
Jaxer examples... I don’t know Java!
Jaxer Image Gallery
http://jxrgallery.aptanacloud.com
Jaxer Image Gallery•Uses sessions•Reads images from file
system•Uses JS file uploads•Works with PHP for
image manipulation

Simple Vote/Poll
http://jxrpoll.aptanacloud.com
Simple Vote/Poll•Uses JS library server-
side (jQuery)•Server-side DOM

DOM Scraping
http://jxrdomscraper.aptanacloud.com
DOM Scraping•Uses Jaxer.Sandbox•Uses new Firefox 3
goodness (getElements ByClassName, built in XPath, etc.)
•Good leverage of client-side async mixed to invoke server-side code
