Either the import section for SimpleEdit class needs java.awt.Toolkit or, on page 53,
private int preferredMetaKey = Toolkit.getDefaultToolkit()... needs the full
java.awt.Toolkit.getDefaultToolkit()... (as you have done in initComponents())
Very minor point: getLabel (page 54) and setLabel (page 53) are deprecated in 1.4.1.
They have been replaced by getText and setText.

Underneath Figure 7.1 |
I needed to insert a "space" character immediately after the ":" in the mainfest file
example to make it work, i.e it needed to be:
"Main-Class: com/wiverson/macosbook/SimpleEdit"
Without the space inserted I got the following jar command error:
java.io.IOException: invalid header field
at java.util.jar.Attributes.read(Attributes.java:359)
