2. (Sect. 4) Where can I find a byte code obfuscator?
[*] Java Obfuscators replace the original class, field and methods
names in the bytecode with meaningless strings. Second generation
obfuscators are now appearing that also obfuscate the control flow and
encrypt String literals. People use obfuscators on their applets if
they want to hide their code from others. Generally, you wouldn't do
this with software that you put on your website for others to enjoy. It
runs counter to the "open source" philosophy of learning from other's
code and allowing them to learn from yours.
Zelix KlassMaster is a commercially supported obfuscator. It has a free
evaluation version at http://www.zelix.com/klassmaster
Another commercially supported obfuscator, with a downloadable free
trial is at http://www.4thpass.com/SourceGuard. There are also some
free works from students and others. http://www.primenet.com/~ej/
http://www.math.gatech.edu/~mladue/HoseMocha.java
Some people have reported problems using these with JDK 1.1.
This obfuscator has been updated to be fully compatible with JDK 1.1:

Obfuscators are intended to foil decompilers. Decompilers translate
byte code back into Java source code. Mocha was the first and most well
known of the decompilers; it's no longer supported. There is a
decompiler (written in C++) at
http://www.geocities.com/SiliconValley/Bridge/8617/jad.html
Because it is in C++, there are different versions for every
architecture (hah!) There are also commercial products, such as
SourceAgain from

There's a very good Java Code Engineering and Reverse Engineering FAQ
page at http://www.meurrens.org/ip-Links/Java/codeEngineering/.
