Short answer: No
Long answer: No, you can't :)

I don't see why not

Well, you can make a keylistener. That's no problem. But you must assign the keylistener to something. Like a frame, or a textbox. What a keylogger does, is listen to a key pressed pretty much anywhere, and that's something you can't achieve with Java.
You'll need VB, c#, c, c++, propably a bunch others, to achieve this.

Java is "stuck" inside its little virtual machine where it's running in. It can't look oustide it to see what's happening. (which is good for security reasons)

I thought the virtual machine was just an interpreter? I'm not saying your wrong, just I didn't know that.

Not with pure Java: it violates the purpose of Java to NOT allow direct access to hardware (needed for keyloggers). JNI might make it possible, but then you're dealing with C/C++ code.
