I just want to catch some values from my form using servlets but i got this error :
There was an unexpected error (type=Not Found, status=404).
No message available
Here is my Servlet :
@WebServlet("/catcher")
public class catchServlet extends HttpServlet
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws IOException
String cityName = request.getParameter("cityName");
String countryCode = request.getParameter("countryCode");
System.out.println("cityName: " + cityName);
System.out.println("password: " + countryCode);
PrintWriter printWriter = response.getWriter();
printWriter.print("City Infos are :nName : " + cityName + " and country code is : " + countryCode);
And my HTML :
<form method="get" name="catchCityInfos" action="catcher">
<p>Name of the City : <input type="text" name="cityName" /></p>
<p>Country code : <input type="text" name="countryCode" /></p>
<input type="submit" value="Submit" />
</form>
The values are going to the URL, but nothing is printed neither in the console nor the /catcher page
I've tried with the post method but it doesnt change anything

Either you haven't deployed your code, or you're not accessing the correct URL. What is the context path of your app? What is the URL displayed in the address bar before and after you sublit the form?

That looks correct. You porbably didn't deploy the servlet correctly. What happens when you add a constructor, aith logging statements inside, and you deploy it? Do you see something in the logs? And when you use your debugger? Is the constructor invoked (if you add one)? Do you have a web.xml file? What does it contain?

Wait, you're using Spring MVC? Then why the hell are you writing a servlet, and not a Spring MVC controller? You need to learn Spring MVC.
