Question: i am looking for a free Webhost for JSF sites..  

unfortunately i didn't find any by Google. 

It is just for testing .. i know .. i could test it with localhost.
but i do want to have real time conditions.

Answer: 
Try Google App Engine. As close to free as you'll get.

Here's an [article](http://ctpjava.blogspot.com/2009/04/jboss-seam-on-google-app-engine-first.html) on getting Jboss Seam running on GAE.
Just buy a virtual host and setup whatever you want. EC2 would work, but you can get a full time server from [linode.com](http://www.linode.com/) starting at just $20 a month or something. I'm sure there are other options out there. Running an EC2 instance all month long would cost about $70 for the cheapest option.
