1. Introducing the Jetty Server

Jetty is an open source project that provides features such as HTTP servers, HTTP clients, and servlet containers.

2. What version of Jetty server should I use?

So far, Jetty9 is the latest version, and has a lot of powerful features than the previous version jetty, but there are still many people using the older version of the jetty server, we solemnly recommend you use Jetty9, because he is the jetty version of the representative, And the official is currently active in Jetty9, and will be maintained for Jetty9 for many years.

Jetty, a lightweight server for Java EE specifications, implemented the important servlet, and the introduction of Web Profile,javaee on the recent Java EE platform was realized that for most developers, only Java EE some of the many techniques.

However jetty does not load all Web profile technology, Jetty's architecture is designed to be a container for third-party implementations that you add to the functionality you really need.

In the fourth edition of the Java EE-7 specification, some of the existing features have been updated and some new features have been added:

JSR	Name	Included with jetty-9.1.x	Pluggable
JSR 340	Servlet Specification API 3.1	Yes
JSR 344	Java Server Faces 2.2 (JSF)	No	Yes, Mojarra or myfaces
JSR 245/JSR 341	Java Server Pages 2.3/java Expression Language 3.0 (jsp/el)	Yes	Yes

I also provide Java EE 6 Web profile as a reference, after all, Java EE 6 is currently the most widely used.

There are many different ways in which you can use the jetty server, embed jetty in your application, or start him on a different build system, based on the different languages of the JVM virtual machine, or deploy the Web application as a separate bundle.

Download Jetty:

The standalone jetty bundle now has a valid connection to the Eclipse Foundation download:

Http://download.eclipse.org/jetty

The files in zip and gzip format are available, and files for your system are downloaded. Note files that end with the extension. sha or. MD5 are checksum files. Unzip in your convenient directory, after extracting the root directory as JETTY_HOME or as $(jetty.home)

The contents directory of the Bundle package:

Location

	Description
License-eplv10-aslv20.html	Jetty's license file
README.txt	Useful Start Information
VERSION.txt	Version information
bin/	Store a shell script that helps to run a utility on a jetty UNIX system
demo-base/	Jetty Basic directory, used to run the Jetty Server sample application
etc/	Jetty related XML configuration file directory files
lib/	Running jetty-related jar packages
logs/	Directory of request logs
modules/	Catalog of modules
Notice.html	License information
resources/	This directory needs to be loaded into additional resources under CLASSPATH (active configuration is active)
start.d/	The directory where INI files are stored, with valid command-line arguments (such as Start.ini)
Start.ini	The file contains the parameter information
Start.jar	Executable jar to start jetty
webapps/	Storage directory for Web applications

Start Jetty

Jetty default is to start on port 8080 and run the command:

CD your jetty unpacked directory Java-jar Start.jar

Then enter http://localhost:8080 in the browser to access it.

After Jetty 9.1, the jetty bundle is a Web application without any examples, so in order to see the interesting Web sample application, you shoulddemo-base目录下面运行下面的命令：

  > CD Jetty Extract folder/demo-base/> Java-jar. /start.jar  2016-02-24 13:56:35.939:warn::main:demo Test-realm is deployed. Do not use the in production!2016-02-24 13:56:35.943:info:oejs.

Also enter http://localhost:8080 in the browser to access, will display the Welcome page and a few demo/test apps.

Tip: The Web sample application does not provide the necessary security measures, please do not publish to the production environment.

Create a new jetty Base

在Jetty 9中demo-baseThe directory is an example based on the jetty.base mechanism, where a jetty.base allows the configuration file and the associated server instance to be saved separately in the jetty bundle. In order to upgrade with minimal loss. Jetty The default configuration is based on two related property configurations.

1.Jetty.home

The attributes he configures are jetty local bundles, default modules, default XML files (typically Start.jar, lib, etc)

2.jetty.base

The attributes he configures are instances, configurations, logs, and Web applications that are locally jetty defined (typically with Start.ini, START.D, logs, and WebApps)
