If you predominantly code in Java, you are better off working in Eclipse, and using some plugin for whatever happens to be your favorite editor. I used to do a lot of Java in the past, and I have used eclipse and vim. Java in plain Vim is a huge PITA - auto complete, generating dummy getter setter, refactoring, fixing imports, checking errors without leaving the ide etc etc. I haphazardly fixed a couple of them using vim plugins and custom keybindings; and then I found eclim, which uses eclipse as a server and provides the functionality in Vim.
