Noddy tip: use Spotlight with Eclipse! 27 Jul 2009
File this under “really obvious but nifty anyway”…
One of the common whinges about Eclipse as a development environment is that there is no decent cross-project / cross-workspace search. I know we Mac users can be insufferably smug, but I’m sorry, Spotlight really does the do here. I was searching for a constant—let us call it WINKLE—and out of the 200-odd classes in a particular project, I could not remember where it was. Go to the Spotlight bar in OS X, type in WINKLE. Narrow your search to your Eclipse Workspace folder if you like, and in a gnat’s fart, you are there:
Now I know you can trace call hierarchies in Eclipse, and that’s a really handy feature. But Spotlight rocks, and this is just one of the ways.

There is also a shortcut to go to implementing class, even if it is in a jar (with SRC additions).
But maybe I misunderstood and you meant searching over project/workspace borders, so this class is not in path.Jan Schulz#
