Here is the example how to write minimal "Hello world" web application using: JSF, gradle as build and dependency management tool, and Tomcat 7 as servlet container.
The project structure you can see on the screenshot:
So you will need to create only 4 files:
1. The first one: build.gradle that should lie in the <project_root> folder and it's content should be:
2. The second one: web.xml that should lie in the <project_root>/src/main/webapp/WEB-INF folder and it's content should be:
The project structure you can see on the screenshot:
So you will need to create only 4 files:
1. The first one: build.gradle that should lie in the <project_root> folder and it's content should be:
apply plugin: 'java'
apply plugin: 'war'
sourceCompatibility = 1.7
repositories {
mavenCentral()
}
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.11'
compile 'com.sun.faces:jsf-api:2.2.8'
compile 'com.sun.faces:jsf-impl:2.2.8'
compile 'javax.servlet:jstl:1.2'
//in this project, you don't actually need this dependency, but there is big probability, that if project is
//more complex than "Hello world" you will need it
providedCompile 'javax.servlet:servlet-api:2.5'
}
2. The second one: web.xml that should lie in the <project_root>/src/main/webapp/WEB-INF folder and it's content should be:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<!-- Change to "Production" when you are ready to deploy -->
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- Map these files with JSF -->
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<!-- Welcome page -->
<welcome-file-list>
<welcome-file>welcome.xhtml</welcome-file>
</welcome-file-list>
</web-app>
3. The third one: welcome.xhtml that should lie in the <project_root>/src/main/webapp folder and it's content should be:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>JSF 2.1 Hello World</title>
</h:head>
<h:body>
<h3>JSF 2.1 Hello World Example - welcome.xhtml</h3>
</h:body>
</html>
4. The last one: settings.gradle that should lie in the <project_root> folder and it's content should be:
rootProject.name = 'HelloWorldApp'
To build the war file you need to call gradle build in command line in the <project_root> folder. The result of build should be the war file lies in the <project_root>/build/libs
After you deploy the artifact to the Tomcat you can see your results by the: http://localhost:8080/HelloWorldApp/
Should be something like this:
