[Solved] See second post.

I set up a new website using WebMatrix and Hellicon Zoo as a new Rails 3.1.3 site (WebMatrix template site, then rails new .). I have the directory permissions set to R/W for Everyone. When I go to the start page, the Rails.png does not show up, but stylesheets are being applied. However when I click on the 'About your applications environment' link, it dies with a 500 error that says it can't find the java runtime. I have tried adding node and execjs to the gemfile one at a time, but neither works. When I start the site using webrick, all is fine. Any suggestions?

PS...Win7 64 bit

500. Error in Helicon Zoo module or application configuration

TransportError: ZooApplication Asynchronous IO Error. GetLastError = The I/O operation has been aborted because of either a thread exit or an application request. dwError=995

OK, so I feel like a total NOOB! Way down on the page it tells you to see the Execjs website where you can find the supported runtimes.

Apparently, when running under WeBrick, it includes some version of a java runtime environment. However that is not available to IIS or WebMatrix. After downloading and installing Node.js under Windows, my site now operates properly.

I had assumed the styling was coming from the compiled SASS and javascript in the assets directory, but in fact it is inline in the welcome page under rails 3.1.3.

It might be a good idea to mention the need to install a runtime as a prerequisite to running WPI, or include one as part of the hosting solution that gets installed by Zoo.

Hello.
It’s nice to see the issue’s been solved.
There is Node.js in our feed: http://www.helicontech.com/zoo/gallery/#NodeJS_Zoo
Rails 3.1 comes with new assets pipeline which is even used in the welcome page. In development mode request to rails.png, for example, goes through Ruby. However before you deploy your application somewhere, you should run “rake assets:precompile” which compiles all CSS/JS and puts them into public/assets folder. There is specific instructions in web.config file which make requests to assets delivered by IIS in production mode.
