Instead, you should design your own user-friendly 404 error page – follow this tutorial: How to Handle Error for Java web applications. So you need to check and use correct case for the letters in request URL.Also pay attention to the webapp name in the URL, for instance is different than TIP: in Eclipse, you can right click on the project, then click Run As > Run on Server, the IDE will always use the correct name of the web application.Finally, you should not let the user see the raw HTTP 404 error page rendered by the server. Anyway my solution was to right click to main class in my project folder and click Run File.

URL is case-sensitiveNote that Tomcat treats URL as case-sensitive, for instance /Register is different than /register. RequestDispatcher dispatcher = request.getRequestDispatcher(registerForm) ĭispatcher.forward(request, response) You can fix by correcting the forward path in the servlet, and make sure that the forwarded resource does actually exist in the given path. The application has a main class MainApp.java with its module-info file that.

Java servlet forwarding to a resource that does not existIn this case, the requested URL is handled by a Java servlet, but code in the servlet forwards to a resource (JSP, HTML…) which does not exist, as shown in the following screenshot: The code in the servlet class would look like this: String registerForm = 'frontend/registerform.jsp' JavaFX and NetBeans Non-modular from IDE Non-modular with Maven. main method not formed correctly ( consult the java tutorial for help) classpath not set up correctly, so that the main class could not be found. Usually, the problem comes from one of the following issues: non public class containing the main method. In older Java web application, you have to check the web deployment descriptor file web.xml because a Java servlet can be mapped to URL via XML like this: If Java comes up with the error message like no main class found you might have a problem like many many others before (as a google query reveals).

You can fix by either correcting the URL or correcting the URL mapping in the annotation. If the request URL is /view_books the server will raise HTTP 404 error. For example: class ViewBookServlet extends HttpServlet This servlet handles the URL /view_book. The URL is not handled by any Java servletsYou need to check URL mapping in your servlet classes to make sure the requested URL is actually handled by a servlet. However, sometimes it’s not easy like that, making it is an annoying error.Here I suggest some possible reasons and how to fix the error HTTP 404 in Java web development with Tomcat. Most of the time, you can fix this error by correcting the URL.

When first a generic class is created and then the Main class is created Netbeans is registering the Main class and the app could be run and debugged. navigators, and HTML) into the ZIP file, is the usual addition to the main attributes area of the module manifest described in Example 27-3: Class-Path. some (rare) Quarkus extensions need to load application classes during the build. The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.This error means the server could not find the requested resource (JSP, HTML, images…) and returns HTTP status code 404. When creating a new project - Maven - Java application in Netbeans the IDE is not recognizing the Main class on 1st class entry. If no extension is found or if more than one extension matches. I was confused about how to name the class and main method.Also, if I want to add a frame, I would have to introduce another class and main method.In Java web development with Tomcat, it’s very often that you get HTTP 404 error like this: The error code is HTTP 404 (not found) and the description is:

I tried to draw a face emoji using the graphics thing, but I typed in the class and it says FaceComponent is not found in the FaceComponent project.
