Vim has a cool jad plugin now. What that means is you can see the decompiled .class files right inside your vim editor. Just load any class file in vim editor and you can see the decompiled version. This is the http://www.vim.org/scripts/script.php?script_id=446 vim plugin and you can download jad from this location http://www.kpdus.com/jad.html . Just copy the vim script to vim plugin folder and put jad in your path. Happy viming ;o)
