Looking for some J2EE hosting

Hi,

Our project is now close to beta, and we're looking for some hosting.
It's a J2EE application, so we need a J2EE app server (any server should work, starting with Tomcat) and a database (any database should work). Of course, the OS is also unimportant.
If you feel ready to help, don't hesitate to join us.
