Web hosting

hi I am new to java applications and have just written my first application using servlets and jsp. i am looking for cheap reliable web hosting so I can test my site other than on local host. Does anyone have any ideas ? Good support is essential as I will probably need it !
is it difficult to transfer from localhost to the web ?
Thanks

We list some in the servlets FAQ:

I'm soon going to be making the transition that Frances describes (localhost to a thrid party).

I've seen javaranch's list of providers (thanks!).

I'm wondering if anyone has insight into whether most of these hosting companies provide virtual hosting services so that I can access my webapp through m own domain name? I used to use the free service my-cgi-server (think it's been renamed). With that service, I could only access my webapp as:

http://mycgiserver/myusername/mywebapp

Anybody know which of the services listed on javaranch supports virtual hosting? I'd like to be able to reach my web apps through:

http://myDomainName/mywebapp

I think just about any commercial host allows you to do this. It's just the free services that don't. Look for a feature called "domain hosting" or something similar. Some will even register the domain for free as long as you host it with them.
