Cannot use "import java.*"

[hqt]

I'm changing to Linux and continue use Intellij IDEA. and my linux use JDK 1.7. I don't know why IDEA doesn't recognize java default package.
So I cannot import something like:

import java.applet.Applet;
import java.awt.*;

I received error: cannot resolve symbol java.
Please help me to solve this problem.

thanks :)
