JSF tags don't render in XHTML pages - Spring Boot + JSF 2.2

Question

I'm trying to implement a webapp using Spring Boot and JSF 2.2.

I've managed to set up Spring Boot correctly and I can display normal HTML with a controller. But XHTML pages are not rendering correctly.

I believe it is to do with my configuration but I cannot figure out what it is.

I'm using IntelliJ IDEA Ultimate 2018.1 on macOS High Sierra.

Here is my pom.xl

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>group</groupId> <artifactId>spring-jsf-webapp</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.3.RELEASE</version> </parent> <properties> <start-class>com.latwoa.Application</start-class> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> <optional>true</optional> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>com.sun.faces</groupId> <artifactId>jsf-api</artifactId> <version>2.2.17</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.sun.faces</groupId> <artifactId>jsf-impl</artifactId> <version>2.2.17</version> <scope>compile</scope> <optional>true</optional> </dependency> </dependencies> <build> <plugins> <!-- Package as an executable jar/war --> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>

My web.xml:

<?xml version="1.0" encoding="UTF-8"?> <web-app 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/web-app_4_0.xsd" version="4.0"> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.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> <welcome-file-list> <welcome-file>index.xhtml</welcome-file> </welcome-file-list> </web-app>

My faces-config.xml:

<?xml version='1.0' encoding='UTF-8'?> <faces-config version="2.2" 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/web-facesconfig_2_2.xsd"> <application> <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> </application> </faces-config>

As well as the JSF bean:

import javax.faces.bean.ManagedBean; import javax.faces.bean.RequestScoped; @ManagedBean @RequestScoped public class JsfBean { private String welcomeMessage = "Populated by JSF created bean"; public String getWelcomeMessage() { return welcomeMessage; } }

And the XHTML page:

<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html" xmlns:f="http://xmlns.jcp.org/jsf/core" xmlns:jsf="http://xmlns.jcp.org/jsf"> <f:view> <h:head></h:head> <!--Main Body --> <h:body> <h1>Welcome to JSF spring boot tutorial</h1> <h:outputText value="foo bar" /> <h3>#{jsfBean.welcomeMessage}</h3> </h:body> </f:view> </html>

Like I mentioned above, the <h1> displays fine. But <h:outputText value="foo bar" /> and #{jsfBean.welcomeMessage} are not rendered.

Did you look at the html source on the client? And then look for duplicate questions. I think (99% sure) it is because you include the jsf api but not the impl — Kukeltje

@Kukeltje I have. The source shows the literal <h:outputText /> tag. I do have jsf-impl in my dependencies, but I hadn't noticed the <optional>true</optional> tag. Could that be causing the error? — LA2A

Sorry, I mixed them up. Would not suspect the optional to be relevant but you could try. And spring boot does already contain the jsf api? — Kukeltje

Spring Boot does not include neither JSF api or the impl. You need both dependencies with the compile scope and not optional. Apart from that, @ManagedBean does not work with Spring Boot (I couldn't have it work myself, at least). Here you've what I did to configure it with Spring Boot 1: stackoverflow.com/a/46190826/1199132 — Aritz

Outined here https://dzone.com/articles/developing-jsf-applications-with-spring-boot

You seem to be missing the step to configure JSF with Spring Boot

@EnableAutoConfiguration @ComponentScan({"com.auth0.samples.bootfaces"}) public class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Bean public ServletRegistrationBean servletRegistrationBean() { FacesServlet servlet = new FacesServlet(); return new ServletRegistrationBean(servlet, "*.jsf"); } }

I'd also add these listeners to integrate spring context with your managed beans:

 <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener>

I have looked at that tutorial before, and adding that @Bean to my Application breaks things more by giving me this error: Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. Fri Jun 22 20:53:42 BST 2018 There was an unexpected error (type=Internal Server Error, status=500). Could not find backup for factory javax.faces.context.FacesContextFactory. I could not find a fix for 'Could not find backup for factory javax.faces.context.FacesContextFactory.'
