Use 32 Bit Eclipse instead of 64 Bit Eclipse.

You most likely don't have the usb driver installed. Get it here: http://mindstorms.lego.com/en-us/support/files/Driver.aspx. Also ensure that your brick is connected and on. Btw, I'll point out that I use 64 bit eclipse and it works perfectly.

That may be the case, and might turn out to be a problem later. However, right now, if you closely look at the exception he posted, you will spot the "windows/x86_64" which indicates that he's using 64Bit Java which is currently not supported on Windows.

It looks like you have the 64bit version of Java and/or Eclipse, for leJOS you must use the 32 bit version because the Lego Fantom library (which is used to communicate by USB), is only available as a 32bit interface...

The tutorial has some notes on this see:
http://lejos.sourceforge.net/nxt/nxj/tu ... clipse.htm
and
http://lejos.sourceforge.net/nxt/nxj/tu ... indows.htm
There are also a number of threads on the forum that may help you resolve this problem...

I get it. The mindstorm drivers are 32 bit.

Ya, but i cant extract it.
it gives me 1500 errors

[gloomyandy]

Extracts fine for me on Windows 7 64bit using the built in zip file handling... Perhaps try re-downloading?

Are you extracting it to a folder without write permission?
