From 223efc5f9969414f104ec98d9b2fad137d0f195b Mon Sep 17 00:00:00 2001 From: Trustin Lee Date: Fri, 23 May 2014 16:46:31 +0900 Subject: [PATCH] Clean up the examples 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. --- .../codec/socks/SocksAuthRequestDecoder.java | 5 - .../codec/socks/SocksAuthResponseDecoder.java | 5 - .../codec/socks/SocksCmdRequestDecoder.java | 5 - .../codec/socks/SocksCmdResponseDecoder.java | 5 -

    This package contains an example web socket web server with server SSL. - *

    To run this example, follow the steps below: - *

    - *
    Step 1. Generate Your Key - *
    - * {@code keytool -genkey -keystore mySrvKeystore -keyalg RSA}. - * Make sure that you set the key password to be the same the key file password. - *
    Step 2. Specify your key store file and password as system properties - *
    - * {@code -Dkeystore.file.path= -Dkeystore.file.password=} - *
    Step 3. Run WebSocketSslServer as a Java application - *
    - * Once started, you can test the web server against your browser by navigating to https://localhost:8081/ - *
    - *
