catalina.LifecycleException: Failed to start

Question

I'm trying to make my Tomcat runs but I keep getting error message Server Tomcat v9.0 Server at localhost failed to start.

I've tried to add commons-logging-1.2.jar to fix the problem, but it's still not working. Any insight would be greatly appreciated! Below is the error log (UPDATED). It does indicate the servlet mapping error with my countycreate jsp file.

This is my web.xml file:

And this is one of my servlet file.. This file locates in the src > servlet folder in my directory:

    package whetherweather.servlet;

@WebServlet("/usercreate")
public class CountyCreate extends HttpServlet {
    
    protected CountyDao countyDao;
    
    @Override
    public void init() throws ServletException {
        countyDao = CountyDao.getInstance();
    }
    
    @Override
    public void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        // Map for storing messages.
        Map<String, String> messages = new HashMap<String, String>();
        req.setAttribute("messages", messages);
        //Just render the JSP.   
        req.getRequestDispatcher("/CountyCreate.jsp").forward(req, resp);
    }
    
    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        // Map for storing messages.
        Map<String, String> messages = new HashMap<String, String>();
        req.setAttribute("messages", messages);

        // Retrieve and validate county id.
        Integer countyId = Integer.parseInt(req.getParameter("idCounty"));
        if (countyId == null) {
            messages.put("success", "Invalid idCounty");
        } else {
            // Create county.
            Integer getcountyId = Integer.parseInt(req.getParameter("idCounty"));
            String getCountyName = req.getParameter("CountyName");
            Integer getDemoId = Integer.parseInt(req.getParameter("Demographics_idDemographics"));
            String getState = req.getParameter("State");
 
       
            try {
                // Exercise: parse the input for StatusLevel.
                County county = new County(getcountyId, getCountyName, getDemoId, getState);
                county = countyDao.create(county);
                messages.put("success", "Successfully created " + countyId);
            } catch (SQLException e) {
                e.printStackTrace();
                throw new IOException(e);
            }
        }
        
        req.getRequestDispatcher("/CountyCreate.jsp").forward(req, resp);
    }
}

I'm 99% sure that the problem is because of the wrong mapping (e.g. in `web.xml` or within the annotation). Post the content of your `web.xml`. — Arvind Kumar Avinash, Jul 11 '20 at 12:35
@TranPham - Do you have any mapping like `/Trial-servlet` in any of your servlets? — Arvind Kumar Avinash, Jul 11 '20 at 18:24
No I don't. I just update one of my servlet file in the question — Tran Pham, Jul 11 '20 at 19:35
@TranPham - Unfortunately, it looks like there exists a mapping, `Trial-servlet` because the error message is `Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/Trial-servlet]]`. Probably, you might have deployed some other application which has this mapping. If you are not able to clean it up, I suggest you try with a new Tomcat instance. I do not see any problem with your code/config. — Arvind Kumar Avinash, Jul 11 '20 at 20:04
