This is an online supply chain management and customer relationship management integrated project.

MySQL or Weblogic runs as database.

The project will be built in EJB and contains Java mobile application.

I need to choose an OS to host this server application. How should I compare from different version of linux? Any review sites to refer, comparison chart? Initially I think of RH enterprise server. But hope to get more comment, idea and suggestion on stablility, intergration with database, support java mobile app (J2ME-based), application server, web server and etc.

Thanks!

Well, in my opinion, any major distro will do. Its mostly a matter of taste and expertise. Some have a couple of graphical tools here and there, others prefer to configure everything by hand.

If you want to go to something very stable, I would choose something like debian, which is also very efficient, and convenient when you have to set up things fast (with apt). They go well through their code, so they may advance a little slower on their stable version, but its really stable. But as I said, its all a matter of taste, you can do almost everything on every distro.
