I'm struggling and can't cope with the simplest, the "printText" method in the Class class, in request.setAttributea JSP servlet, displays an error 500, look at the code, what's wrong? Tomcat8, IntelliJ IDEA Ultimate

Class, Servlet:

public class Servlet extends HttpServlet {

public class PrintText {
    public String printText() {
              return "Hello!";
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {

         PrintText p = new PrintText();
         p.printText();
         request.setAttribute("p", p); 
         request.getRequestDispatcher("/WEB-INF/index.jsp").forward(request, response);
    }
    }

jsp:

<html>
<body>
<p>${p.printText}</p> 
</body>
</html>

Replace the name of the printText method with getText, and the EL expression with ${p.text}
