Could not find backup for factory javax.faces.context.FacesContextFactory

Hello,

We are shifting a JEE app from Wildfly to Spring Boot.

I’ve updated our pom.xml to use joinfaces:

<parent>
	<groupId>org.joinfaces</groupId>
	<artifactId>joinfaces-parent</artifactId>
	<version>3.2.0</version>
	<relativePath />  
</parent>

<dependency>
	<groupId>org.joinfaces</groupId>
	<artifactId>primefaces-spring-boot-starter</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-aop</artifactId>
	<version>2.0.2.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework.data</groupId>
	<artifactId>spring-data-jpa</artifactId>
	<version>2.0.6.RELEASE</version>
</dependency>

Running the Spring Boot application from Eclipse Oxygen reports the application has started. However, when I navigate to a page in the application in the browser, I get the following stacktrace:

I see that the Mojarra jars were resolved in the pom.xml so they are present. I don’t see any MyFaces jar files. I am not sure how to proceed further in troubleshooting this issue. Does anybody have any ideas that could help me out?

Thanks! Dave
