SpringUtilities cannot be resolved

I'm trying one of the Oracle's GUI examples that uses SpringUtilities. But the Eclipse gives me and error Cannot resolve to type and when I try to compile I get SpringUtilities cannot be resolved. I'm using 1.7 JDK, guess I have to add something somewhere but I can't find much info about this problem on the internet.

Solution

  • SpringUtilities isn't included in the JDK/JRE. It's used in their SpringLayout tutorial,

    http://docs.oracle.com/javase/tutorial/uiswing/layout/spring.html

    The source is linked to from that page, and can be viewed at
