In your screenshot, the packages aren't empty - the don't contain classes, but subpackages. That's why you can't delete them.
Take a look at the menu of the package explorer (the black triangle at its right top, if I remember correctly). If I remember correctly, there is a layout entry where you can change from "flat" to "tree". There might even be an option to filter empty packages in the flat view, I'm not sure.

I found I was able to permanently remove them, not just filter them if I removed the packages from the build path first. If I didn't remove them from the build path, they would pop back, and it was playing havoc with my war export.
