Does anyone know of an Internet hosting organization where I may deploy a WAR web application? I need to have Tomcat 5.5 and MySQL available. And of course, the platform should be Unix (Solaris/Linux).
One such company is WebAppCabaret. A plan that lets you use the latest Tomcat and MySql will cost you $17/month, and they have other plans with more features. (I have no financial interest in them, aside from being a satisfied customer.)
An age-old list of other options can be found here.
