Ask HN: Who can host a jboss portlet written from eclipse?

If I make a jboss portlet in my eclipse and it is published to localhost, how can I get it hosted on the web ("the cloud", etc.). What cheap hosting service can I use to zip up my .war file and so forth and send it to them to host on the web? Just any old web hosting company? Or does it have to be specific? Thinking of playing around with portlets as an excercise and wondered whom I could get to host.
