Motivation: The examples have not been updated since long time ago, showing various issues fixed in this commit. Modifications: - Overall simplification to reduce LoC - Use system properties to get options instead of parsing args. - Minimize option validation - Just use System.out/err instead of Logger - Do not pass config as parameters - just access it directly - Move the main logic to main(String[]) instead of creating a new instance meaninglessly - Update netty-build-21 to make checkstyle not complain - Remove 'throws Exception' clause if possible - Line wrap at 120 (previously at 80) - Add an option to enable SSL for most examples - Use ChannelFuture.sync() instead of await() - Use System.out for the actual result. Use System.err otherwise. - Delete examples that are not very useful: - applet - websocket/html5 - websocketx/sslserver - localecho/multithreaded - Add run-example.sh which simplifies launching an example from command line - Rewrite FileServer example Result: Shorter and simpler examples. A user can focus more on what it actually does than miscellaneous stuff. A user can launch an example very easily.
