So, we’ve chosen some hosting. Turns out that there are very few Java application hosts, and there isn’t much info on the web in the way of decent hosting reviews. I did find, amazingly, that some of the hosting providers even have clauses in their small print about what third party jars your application is allowed to use.
We’ve gone for http://www.kattare.com an so far they’ve been great; a speedy turnaround, no restrictions on the type of applications we can deploy, easy ssh access, good control over the server and so far also helpful support who get back to you quickly.
