I am struggling to get a simple Hello World app to run on Eclipse using the latest versions of Spring Boot, CDI, JSF and Primefaces.
Here is the error message I get when starting the application:
2023-04-10T02:05:29.078+02:00 INFO 17656 --- [ main] o.apache.catalina.core.StandardEngine : Starting Servlet engine: [Apache Tomcat/10.1.7]

Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

Here is the TestBean.java:
package com.psbase.test;
import jakarta.annotation.PostConstruct;
import jakarta.faces.view.ViewScoped;
import jakarta.inject.Named;
@Named
@ViewScoped
public class TestBean{
private String text;
@PostConstruct
public void init() {
text = "Hello World!";
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public void handleKeyEvent() {
text = text.toUpperCase();
}
}
Here is the Main.java:
package com.psbase.test;
import java.util.Arrays;
import jakarta.faces.webapp.FacesServlet;
import jakarta.servlet.Servlet;
import jakarta.servlet.ServletContext;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
@SpringBootApplication
public class Main{
public static void main (String[] args) {
SpringApplication.run(Main.class, args);
}
@Bean
ServletRegistrationBean<Servlet> jsfServletRegistration (ServletContext servletContext) {
//spring boot only works if this is set
servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
//registration
ServletRegistrationBean<Servlet> srb = new ServletRegistrationBean<Servlet>();
srb.setServlet(new FacesServlet());
srb.setUrlMappings(Arrays.asList("*.xhtml"));
srb.setLoadOnStartup(1);
return srb;
}
}
I tried to use older version of the dependencies, so that I use javax instead of jakara, or so that I use @ManagedBean annotations instead of @Named annotation (that use CDI). Also I tried different embedded web container (beside Tomcat)
When not using the latest version, my code at least runs, alhtough the data in the XHTML view are not displayed like they should (as if the EL did not work)
