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. URL is case-sensitiveNote that Tomcat treats URL as case-sensitive, for instance /Register is different than /register.

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. Apache Tomcat is a web server and servlet.

There are three kinds of error prompts that contains the error In such a case try the more advanced solutions below. 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.

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. The workflow is applicable to any Identity Provider compatible with SAML 2.0 protocol.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:
