This is a step-by-step guide to create a "contract-first" web service with Apache CXF. It's a lot easier than doing the same thing with Spring-WS. The project uses standard Maven directory layout. Define the data types ( src/main/resources/hello.xsd ):

The default servlet for Tomcat is declared in $CATALINA_HOME/conf/web.xml :
<servlet>
<servlet-name>default</servle...
Therefore, static content is rendered by the default configuration unless you override it with your own definitions.
If you want to allow directory listing, just change the listing parameter to true :
<init-param>
<param-name>listings</para...
Change the welcome-file-list to display a default page in lieu of a directory listing:
<welcome-file-list>
<welcome-file>home.xhtml</...
Welcome pages are defined at the Web application level.

This is a bare bones Maven project to get started with Java JSR 303 bean validation.
Directory structure:
./pom.xml
./src
./src/main
./src/main/jav...
pom.xml :
<project xmlns="http://maven.apache.org/POM/4.0.0"...
which includes dependencies on JUnit, Java bean validation API and the Hibernate validator reference implementation.

This is a simple Hello World application with Spring 3 MVC. Like the default Apache HTTPd welcome page, it displays " It works! " when successfully deployed. The sole purpose is to show the minimum elements needed to setup Spring 3 MVC.
I use Maven since it's so much easier than downloading the dependencies manually.
Directory layout:
./src
./src/main
./src/main/webapp
./src/...
pom.xml :
<?xml version="1.0" encoding="UTF-8"?>
<project...

This is a simple JSP custom tags library with tag body. Just like the JSF counterpart , it splits a string and repeats the body for each word, i.e., with this markup:
<%@ taglib uri="http://custom.tag.com/demo" prefix...
output:
<html>
<body>

By default, tomcat uses an enhanced java.util.logging implementation called JULI, which can be configured at two different levels: Globally, with the ${catalina.base}/conf/logging.properties file. Per web application, with WEB-INF/classes/logging.properties . The configuration file is a normal Java properties file: Logging handlers are specified with the handlers property.
handlers = 1catalina.org.apache.juli.FileHandler, ... The root logger can define its set of handlers using the .handlers property. .handlers = 1catalina.org.apache.juli.FileHandler,... A prefix may be added to handler names. The prefix starts with a digit and ends with a dot ( . ), for example: # 1catalina. is a prefix 1catalina.org.apache.j... System property replacement is performed for property values which contain ${systemPropertyName} . Each handler can have its own specific properties: 3manager.org.apache.juli.FileHandler.level = FINE ... Loggers can define their own...

Tomcat allows you to create multiple server instances for the same installation. The installation directory is identified as CATALINA_HOME , the instance directory is identified as CATALINA_BASE . Here are the steps: Create a base directory for the new instance, for example: /home/nogeek/tomcat1 . Create the subdirectories:
mkdir -p /home/nogeek/tomcat/{bin,conf,logs,temp,w... Copy web.xml from the installation directory: cp $CATALINA_HOME/conf/web.xml /home/nogeek/tomcat...

I need Maven to generate web.xml based on the target environment. For example:
<context-param>
<param-name>javax.faces.P...
should be translated to
<context-param>
<param-name>javax.faces.P...
for the dev environment, and to
<context-param>
<param-name>javax.faces.P...
in the prod environment.

By default, alfresco.log is located in the current working directory (where you started Tomcat from). But you can override the default location with a custom lo4g.properties file:
Create file $TOMCAT_HOME/shared/classes/alfresco/extension/custom-log4j.properties with contents:
log4j.rootLogger=error, File
log4j.appender...
The Alfresco log will be relocated to /home/alfresco/logs (but somehow s small portion remains in the CWD).
This works only when the shared.loader property in conf/catalina.properties includes ${catalina.home}/shared/classes .
