1.创建项目
mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp
也可参看这里
创建要注意遵循MAVEN的目录结构，尤其要注意源文件要放在main/java下：
2. POM文件的配置
这里要特别注意对resource一节的配置，因为我的SPRING以及WEB相关的XML是放在WEB-INF目录，为了在unit test的时候也能用，加入了对这些配置文件的引用。相当于加了一个classpath。
这里还有个插曲：不知为何MAVEN2里没有JTA的包，自动下载时会有提示教你如何手工通过命令加入，非常简单。
JETTY的plugin是为后面用它来调试做准备。
DWR也是目前WEB开发一个热选。
另外，为使用JAVA5代来编译，加入了maven-compiler-plugin一节。

代码放入/main/java后，可以在项目目录下执行：
mvn compile来做编译尝试，
也可以用mvn war直接生成打包文件，
当然最后可以用 mvn jetty:run来运行你的WEBAPP!
3. 在Eclipse中配置jetty进行调试
要把之前的项目导入Eclipse首先让maven为我们生成Eclipse工程文件，执行：
mvn eclipse:eclipse
再把M2_REPO加入到Eclipse的classpath中，有两种方法，其中的b)方法是有效的：
a) mvn -Declipse.workspace=<path-to-eclipse-workspace> eclipse:add-maven-repo
b) Window > Preferences. Select the Java > Build Path > Classpath Variables page
之后，就可以通过Eclipse的File->Import功能将工程导入。
有人为了使用WEBAPP开发功能，而装象MYECLIPSE这样的巨物。有了JETTY，通过轻松配置就可以实现比TOMCAT更快更便捷的容器，所以在调试时强力推荐这个东东。下面就来看下如何配置。
先下配置一个外部工具，来运行JETTY：
选择菜单Run->External Tools->External Tools ...在左边选择Program，再点New：
配置Location为mvn完整命令行。
选择Working Directory为本项目。
Arguments填写：jetty:run
再点选Enviroment页：加入MAVEN_OPTS变量，值为：
-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=y
其中，如果suspend=n 表示不调试，直接运行。
然后，点APPLY，再关闭本对话框。
另外注意一点，好像external tool菜单项在java browering的perspective下才会出现。如果在java下看不见，可以切换下试试。
下面新建运行配置：
点选run->debug...
选中左树中的Remote Java Application，再点New。
选择你的项目，关键是要填和之前设置外部工具时相同的端口号。
配置就完成了，正面开始调试运行：
首先要把JETTY运行起来(有点象TOMCAT里的运行APPSERVER)，从Run->External Tools中选择之前配置的外部工具运行，这时LOG里会显示：
listening at port 4000字样，
再选择Run->Debug选择我们刚建的运行配置，这时程序就RUN起来了，可以通过WEB进行访问，设置断点调试了。
============================================================================
适用于6.1.3以上，包括6.1.5的JETTY。
它主要是利用了JDK的代码自动更换性能(code hot replace)，可以不用重启JETTY就调试、更换资源文件。注意：一定是DEBUG方式运行才有这项功能。
所以应该说这篇文章的方法更好：
在Run->Debug中，New一个Java Application的配置，填入：
org.mortbay.xml.XmlConfiguration
参数填入一个自己的JETTY配置文件：
完成的myjetty.xml配置文件，请将其中的相应目录修改成自己项目的目录：
<? xml version="1.0" ?>

-
Maven
1. 创建普通工程:mvn archetype:create -DgroupId=com.example -DartifactId=example
2. 创建Web工程:mvn archetype:create -DgroupId=com.example -DartifactId=example -DarchetypeArtifactId=maven-archetype-webapp
-
eclipse
1. 转为eclipse工程:mvn eclipse:eclipse
2. 添加repository路径变量m2_repo:mvn eclipse:add-maven-repo -Declipse.workspace=your eclipse workspace path
-
Jetty
1. 修改POM.xml文件，指定工程使用Jetty及Java5
xml 代码

2. 工程调试:添加外部工具
Step 1
Go to the Run/External Tools/External Tools ..." menu item on the "Run" menu bar. Select "Program" and click the "New" button. On the "Main" tab, fill in the "Location:" as the full path to your "mvn" executable. For the "Working Directory:" select the workspace that matches your webapp. For "Arguments:" add jetty:run .
Move to the "Environment" tab and click the "New" button to add a new variable named MAVEN_OPTS with the value:
-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n
If you supply suspend=n instead of suspend=y you can start immediately without running the debugger and launch the debugger at anytime you really wish to debug.
Step 2
Then, pull up the "Run/Debug/Debug ..." menu item and select "Remote Java Application" and click the "New" button. Fill in the dialog by selecting your webapp project for the "Project:" field, and ensure you are using the same port number as you specified in the address= property above.
Now all you need to do is to Run/External Tools and select the name of the maven tool setup you created in step 1 to start the plugin and then Run/Debug and select the name of the debug setup you setup in step2.
3. js、css等静态文件无法更新的问题(save could not be completed )
原文出处
Jetty启动后，如果修改javascript文件，将不能保存，使调试很麻烦。这是因为使用了CACHE，JETTY说是WINDOWS下的一个限制。可以通过如下方法修正：
解压出jetty.jar中的 org/mortbay/jetty/webapp/webdefault.xml文件，将这一选项由true改为false，另存到src/main/resources目录，或者其它自选目录。
xml 代码
<!-- change to false -->
- < init-param > < param-name > useFileMappedBuffer param-name >
- < param-value > true param-value > <!-- change to false --> init-param >
在pom.xml中加入对这个文件的指向:
xml 代码
- < plugin >
-
< groupId > org.mortbay.jettygroupId >
-
< artifactId > maven-jetty-pluginartifactId >
-
< configuration >
-
< webDefaultXml > src/main/resources/webdefault.xmlwebDefaultXml >
