Thread: ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet

I found a lot of forums telling about the error I typed in subject and I did try every suggestion without success. I did include the servlet-api.jar from Tomcat7 lib folder to Java Build Path
In Eclipse I have:
src/main/java/tutorial/mvc/TestController.java
src/main/webapp/WEB-INF/mvc-dispatcher-servlet.xml
src/main/webapp/WEB-INF/web.xml
src/main/webapp/WEB-INF/jsp/view.jsp

1 - TestController.java
package tutorial.mvc;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class TestController {
	@RequestMapping("/test")
	public String test(){
		return "view";
	}
 
}

When I look at Problem window I see
Cannot change version of project facet Dynamic Web Module to 3.0. basic-web-app line 1 Maven Java EE Configuration Problem
Java compiler level does not match the version of the installed Java project facet. basic-web-app Unknown Faceted Project Problem (Java Version Mismatch)
One or more constraints have not been satisfied. basic-web-app line 1 Maven Java EE Configuration Problem
Project facet Java 1.8 is not supported by target runtime Apache Tomcat v7.0. basic-web-app Unknown Faceted Project Problem

Did you read this part of the error message:

Project facet Java 1.8 is not supported by target runtime Apache Tomcat v7.0.

Thanks. I changed to 1.7 but I am still getting the same error from the subject of this thread.
PS. instead of 5 lines in problem window now I have two but I don't know what to do:


Cannot change version of project facet Dynamic Web Module to 3.0. basic-web-app line 1 Maven Java EE Configuration Problem
One or more constraints have not been satisfied. basic-web-app line 1 Maven Java EE Configuration Problem

Thread moved.
