I saw there is a lot of similar questions and answers for my situation, but the problem is none of them worked for me! I'm trying to learn JSF and Spring boot and I've used some tutorials for them to manage this little simple code, but It does not work. The problem is Eclipse knows my Managed Bean and it's properties in jsf page, and my page renders perfectly, but when I enter numbers and click on any of my command buttons, the error appears! I thought maybe it cannot find target classes, so I tried to define it with
<build>
<outputDirectory>src\main\webapp\WEB-INF\classes</outputDirectory>
but nothing different happened! Would you please help me? My pom.xml is:
