19 warnings while compiling JUnit... is this normal?

[WarpZone32]

At the advice of a friend I've installed Eclipse SDK v.3.2.1 on my Windows 2000 machine. Just recently I attempted the "Creating your first Java project" tutorial which basically walks a new user through the process of compiling JUnit. (I grabbed the source for JUnit 3.2 from sun's website rather than 3.2.1 which was "the latest edition," because the documentation called 3.2 the latest edition and I figured this was the surest way to get the same results as when the helkp file was written.) Anyway, I followed the instructions and I think it compiled, but I got 19 warnings, including:

Is this normal, or did the compile fail for some reason?

Needless to say, I am a total beginner, and I did not compile this build of eclipse myself. I got it as a distro from IBM's mirror.

Thanks in advance for any helpful replies. I'm a bit bewildered by the sheer number of options before me, just trying to find the right IDE and get it installed and running. All this before I even touch my first line of code! So I want to make sure I'm doing it right before I get in any deeper.

Thanks again.
