    Default Trying to write a servlet, keep getting 404 errors in web browser.

    Hey guys,

    I'm usually pretty good with this stuff, but Servlets are kicking my ass. The logic all seems straightforward enough, but I can't figure out the environment.

    Here's my setup: running Tomcat through XAMPP and using port 9999. The files themselves are all in a Dropbox folder. So the root here is: C:\Dropbox\xampp\tomcat\webapps\servletprojects

    For this particular servlet, it's part of a larger project that also has some Javascript elements with some HTML pages and a style sheet. That is in:

    C:\Dropbox\xampp\tomcat\webapps\servletprojects\Hi gherNumbersProject

    Under that, I have the folder C:\Dropbox\xampp\tomcat\webapps\servletprojects\Hi gherNumbersProject\WEB-INF and within there I have C:\Dropbox\xampp\tomcat\webapps\servletprojects\Hi gherNumbersProject\WEB-INF\classes

    Inside the WEB-INF folder I have my web.xml file:

    <?xml version="1.0" encoding="ISO-8859-1"?>
    <web-app version="3.0"
      xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    Inside the classes folder I have process_login.class

    And here is the code for my servlet. There's not much there yet, I just want to get text on the web browser screen.

    import java.io.*;
    import javax.servlet.*;
    import javax.servlet.http.*;
    public class process_login extends HttpServlet
    	 public void doGet(HttpServletRequest request, HttpServletResponse response)
    	         throws IOException, ServletException 
    		 		PrintWriter out = response.getWriter();

    So then I tell Eclipse to build the file. It generates the process_login.class file. I can't figure out how to get Eclipse to put it into the \WEB-INF\classes folder... it puts it in the project's main folder C:\Dropbox\xampp\tomcat\webapps\servletprojects\Hi gherNumbersProject right next to the process_login.java file. I've just been copying the .class file over manually. Any advice on how to get Eclipse to put the .class file where I want it is appreciated. But that isn't my main issue.

    Lastly I point Firefox over to http://localhost:9999/servletproject.../process_login

    But all I get is a 404 page:

    HTTP Status 404 - /servletprojects/HigherNumbersProject/process_login

    type Status report

    message /servletprojects/HigherNumbersProject/process_login

    description The requested resource is not available.
    Apache Tomcat/7.0.30
    Am I fundamentally misunderstanding the setup of servlets? Or is there some mundane detail I am missing?

    This is really frustrating because I like to think I'm a pretty smart guy and I can figure this stuff out with enough effort, but I am absolutely hitting a wall here and burning off a lot of time. It's part of a larger class project which is due in 3 weeks. Though.... thank God I already got the Javascript, basic HTML layouts, and styling done. If I can clear this hurdle and just get the stupid servlets working I think I can plow through the internal code logic fairly quickly.

    Disregard (dunno if anyone read this). I figured this out. Turns out you can only have one WEB-INF within a folder no matter how many different other folders within that folder.
