Note: if you downloaded the Sample files on or after January 13, 1998,
the fixes are incorporated into the code already and you do not
need to reapply them.

Some general comments about the use of the sample code for
Developing Java Beans:

There are, in fact, a number of mistakes in the code.  I apologize
to anyone that has been inconvenienced or frustrated by these
errors.  The section below (Code Fixes) addresses these mistakes.

I have attempted to address these changes based upon jdk 1.2 beta 2.
In doing so, I have discovered that the new security management
architecture breaks the serialization code in chapter 5 (and elsewhere).
This is due to the fact that I open FileInputStream and FileOutputStream
objects, which now cause a security violation.  I have not attempted
to direct the reader to the proper way to deal with this as I am not
familiar with the new security architecture, so this should be noted.

Here are a few pointers for compiling the code:

- make sure your CLASSPATH variable points to your current directory,
  as well as the root of your package path.
- the code examples that are not part of a package should be compiled
  and executed from a common directory.
- the code examples that are part of package BeansBook.util should
  be compiled and run from the appropriate BeansBook\util package directory.
- the code examples that are part of package BeansBook.Simulator should
  be compiled and run from the appropriate BeansBook\Simulator package directory.
- the code should be compiled in the order that it appears in the book!
- code is placed into chapter directories in the ZIP file so that the reader knows where to
  look for it on a chapter by chapter basis.  before compiling, the code
  should be placed into the appropriate directory, either the common directory,
  the BeansBook\util directory, or the BeansBook\Simulator directory, as appropriate.
- code that evolves within a chapter is annotated with a .1, .2, etc, indicating
  the sequenced evolution of the code within the chapter.
- I haven't provided any sample HTML files for running the sample applets, as that
  should be a no brainer for the reader.
