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 ): <xs:schema xmlns:xs=" Define the service ( src/main/resources/hello.wsdl ): <?xml version='1.1' encoding='UTF-8'?> <wsdl:de... Create pom.xml : <project xmlns=" Generate jaxb bindings: $ mvn generate-sources Code the web service ( src/main/java/com/example/cxfdemo/ ): package com.example.cxfdemo; import javax.j...

Spring-WS documentation says you can use a Jaxb object as parameter or return type, provided that it is annotated with javax.xml.bind.annotation.XmlRootElement , or is an instance of javax.xml.bind.JAXBElement . But that's a lot easier said than done! For example, if sayHelloResponse is defined as: <xs:element name="sayHelloResponse" type="tns:sayH... then the JAXB generated class is not annotated with XmlRootElement , therefore, unusable for Spring-WS. You have to define the type as: <xs:element name="sayHelloResponse"> <xs:compl... in order to generate a type annotated with XmlRootElement . But that is not always possible. Alternatively, you can use the Maven plugin maven-jaxb2-plugin with the jaxb2-basics-annotate plugin (yes, plugin inside plugin) to inject the XmlRootElement annotation into the generated JAXB class. This is the pom: <project xmlns=""... and the binding file: <?xml version="1.0" encoding="UTF-8" standalone="y......

Create the web service interface ( src/main/java/jaxws/ ): package jaxws; import javax.jws.WebService;... Implement the web service ( src/main/java/jaxws/ ): package jaxws; import javax.jws.WebService;... Create src/main/webapp/WEB-INF/cxf-servlet.xml : <?xml version="1.0" encoding="UTF-8"?> <beans x... Register the CXF servlet in src/main/webapp/WEB-INF/web.xml : <?xml version="1.0" encoding="UTF-8"?> <web-app... Build: mvn package The resulting WAR file can be deployed to any servlet container (for example, Tomcat).

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... WEB-INF/web.xml : <?xml version="1.0" encoding="UTF-8"?> <web-app...

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... Copy from the installation directory: cp $CATALINA_HOME/conf/ /home/no...

Values of Maven properties are accessed with the construct ${...} . Properties come from 5 different sources: From the environment, for example: ${env.PATH} , ${env.JAVA_HOME} . From the POM, in the form of ${project.x} . For example: ${project.version} , ${project.groupId} . From settings.xml , in the form of ${settings.x} . For example: ${settings.offline} , ${settings.interactiveMode} . From Java system properties, for example: ${java.home} . Defined within the properties element in the POM. For example ( gae.version ): <properties> <gae.version>1.4.2</

In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print <p>john</p> <p>steve</p> <p>mike</p> with custom tag <my:foreach> : <my:foreach var="who" value="john steve mike"> ... These are the files: pom.xml <project xmlns=""... src/main/java/com/example/ : package com.example; import src/main/resources/META-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <faces-c... src/main/resources/META-INF/foreach.taglib.xml : <?xml version="1.0" encoding="UTF-8"?> <facelet... How to use: Put the JAR file generated by the above project in the WEB-INF/lib folder of the web app. If the web app is a Maven project, just add the taglib project as a dependency:...
