paragraph 3: Replace with

One significant problem we've faced is Sun's waffling on the Swing
package names. Swing was first released in the com.sun.java.swing
package hierarchy, which was supposed to be a temporary resting place.
With JDK 1.2, Swing was supposed to move into the java.awt.swing
hierarchy. For some reason, Sun backed off, and kept Swing in the
com.sun hierarchy for beta 4. They then moved it to javax.swing for
the first official release of JDK 1.2--except for a few oddball
platform-specific packages (like the Windows look-and-feel) that
remain in com.sun. We've been at our wit's end trying to fix the
package names, both in the book and in the online source files. At
any rate, for JDK 1.2 and Swing 1.1 (for use with JDK 1.1), the major
Swing classes are in the following packages:

para 2 (description for com.sun.java.swing.plaf--which,

replace with:

"Classes supporting "pluggable look-and-feel", including classes that
implement the Metal and Multi look-and-feels. (Implementations of the
Windows and Motif L&Fs are packaged under com.sun.java.swing.plaf.)
Covered in Chapter 26, Look & Feel."

About the Source Code: Add at the end of the section

"The examples are available as a JAR file, a ZIP archive, and as a
compressed TAR archive. The files named swing-old use the old
(com.sun) package hierarchy, and have been tested against JDK 1.2 beta
4. The files named swing have been converted to the new (javax)
package hierarchy, and have been tested against JDK 1.2 Release
Candidate 1."
