- Add the HelloBean.java file
- Add the web.xml file
- Add the beans.xml file
- Add an integration test
- Test the application

Create the Maven POM file
Create an empty directory to store your Maven project. Inside of that directory
create the pom.xml file with the content as below.

Add the Hello Faces XHTML file
Add the helloworld.xhtml file in the src/main/webapp directory.
<?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 lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="jakarta.faces.core"
xmlns:h="jakarta.faces.html"
xmlns:pt="jakarta.faces.passthrough">
<h:head>
<title>Jakarta Faces application</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
</h:head>
<h:body>
<div>Jakarta Faces application</div>
<h:form>
<h:outputText value="#{helloBean.hello}"/>
<br/>
</h:form>
</h:body>
</html>
Add the HelloBean.java file
Add the HelloBean.java file in the src/main/java/hello directory.
package hello;
import jakarta.enterprise.context.RequestScoped;
import jakarta.inject.Named;
@Named(value = "helloBean")
@RequestScoped
public class HelloBean {
private String hello = "Hello from Jakarta Faces!";
public String getHello() {
return hello;
}
public void setHello(String hello) {
this.hello = hello;
}
}
Add the web.xml file
Add the web.xml file in the src/main/webapp/WEB-INF directory.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>jakarta.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
</web-app>
Add the beans.xml file
Add the beans.xml file in the src/main/webapp/WEB-INF directory.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_2_0.xsd"
bean-discovery-mode="all">
</beans>
Add an integration test
As we want to make sure the application gets tested before we release an integration test is added which will be executed as part of the build.
We'll add the integration test to the src/test/java directory.
package hello;
import java.net.URI;
import java.net.http.HttpClient;
import static java.net.http.HttpClient.Redirect.ALWAYS;
import java.net.http.HttpRequest;
import java.net.http.HttpResponse;
import java.net.http.HttpResponse.BodyHandlers;
import java.time.Duration;
import static org.junit.jupiter.api.Assertions.assertTrue;
import org.junit.jupiter.api.Test;
public class HelloIT {
@Test
public void testHelloFacesXhtml() throws Exception {
HttpClient client = HttpClient
.newBuilder()
.connectTimeout(Duration.ofSeconds(60))
.followRedirects(ALWAYS)
.build();
HttpRequest request = HttpRequest
.newBuilder(new URI("http://localhost:8080/faces/hellofaces.xhtml"))
.build();
HttpResponse<String> response = client.send(request, BodyHandlers.ofString());
assertTrue(response.body().contains("Hello from Jakarta Faces!"));
}
}
Test the application
The application is setup to use JUnit to do integration testing using the Piranha Maven plugin so when you are building the application it will also execute an integration test validating the web application works.
To build and test the application execute the following command:
mvn install
Deploy the application
To deploy your application you will need 2 pieces.
- The Piranha Web Profile runtime JAR.
- The WAR file you just produced.
For the WAR file see the target directory. For the Piranha Web Profile
distribution go to Maven Central. And then the following command line will
deploy your application:
java -jar piranha-dist-webprofile.jar --war-file faces.war
Conclusion
As you can integrating Jakarta Faces with Piranha Servlet can be done quickly!
