SpringUtilities could not be resolved

Question

I am trying to use one of the Oracle GUI examples that uses SpringUtilities . But Eclipse also gives me Cannot resolve to type error, and when I try to compile, I get SpringUtilities cannot be resolved . I am using 1.7 JDK, I think I need to add something, but I can not find much information about this problem on the Internet.

Answer 1

SpringUtilities not included in the JDK / JRE. It was used in the SpringLayout tutorial,
