First up sign in is super simple, just your email and thats all you need. The user interface is clean, powerful and incredibly simple. With simple drop downs to create your environment and configure the number of instances etc that you need. In just a few minutes you can be up and running.
So i chose Tomcat 6. I did initally try Tomcat 7 but apparently they have a few problems with 7 at the moment. Not to worry 6 is fine. Deploy your environment and then wait for it to be deployed. This takes just a minute or so while they build your instance.
Once you've uploaded the .war file, you need to deploy it. Simple, still in the deployment manager tab, click on the box dropdown and click deploy. It'll ask you to confirm "ROOT" as the context, but root is fine. Once this is done you should be able to click the "launch in browser" button and see the railo admin show.
That's it, you're basically done. I expect you want your own application to run, but that's just as easy. If you click on the spanner / config option next to Tomcat 6 a settings tab will open and you can tweak the tomcat settings. Expand webapps and root. This is your application home, you can delete everything in there except for the WEB-INF folder. Then upload your cfm files and you're done!I think this is a brilliant hosting environment and so brethlessly simple I'm very impressed.
