my nokia 6630 installer do't install any java application.how do i go about it.

What Java apps are those, exactly? Hopefully MIDP 2.0 MIDlets, and no other kind.

What, exactly, do you mean with "6630 installer"? The [Application] Manager on the phone? The PC Suite Application Installer on your PC? Something else?

Also, what does "do't install" mean? What do you try (step-by-step)? What happens (a description of what you see, including any and all error messages as displayed, word-for-word)?
