Need to make a servlet class default in tomcat

Question

I have tried previous methods mentioned in other answers but still http://localhost:8080/InterConnect/ is showing 404 error. whereas http://localhost:8080/InterConnect/servlet/HomePageServlet page is running smoothly.

web.xml file:-

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>

<!-- Define servlets that are included in the example application -->

<welcome-file-list>
    <welcome-file>HomePageServlet</welcome-file>
</welcome-file-list>


<servlet>
    <servlet-name>SignInServlet</servlet-name>
    <servlet-class>SignInServlet</servlet-class>
</servlet>

<servlet>
    <servlet-name>SignUpServlet</servlet-name>
    <servlet-class>SignUpServlet</servlet-class>
</servlet>

 <servlet>
    <servlet-name>HomePageServlet</servlet-name>
    <servlet-class>HomePageServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>SignInServlet</servlet-name>
    <url-pattern>/servlet/SignInServlet</url-pattern>
</servlet-mapping>

<servlet-mapping>
   <servlet-name>SignUpServlet</servlet-name>
   <url-pattern>/servlet/SignUpServlet</url-pattern>
</servlet-mapping>

<servlet-mapping>
   <servlet-name>HomePageServlet</servlet-name>
   <url-pattern>/servlet/HomePageServlet</url-pattern>
</servlet-mapping>

Using tag with a value, but this is also not working. And tag — Sukhbir, Jun 25 '16 at 20:22
Have you tried this for the `/` for the HomePageServlet servlet-mapping — Michael Markidis, Jun 25 '16 at 20:27

When browser requests http://localhost:8080/InterConnect/, assuming InterConnect is the context path, and given that you have declared <welcome-file>HomePageServlet</welcome-file>, the servlet container will look to see if a servlet mapping exists for /HomePageServlet.

You don't have a mapping for /HomePageServlet, only one for /servlet/HomePageServlet, so the web server returns 404 (Not found).

Try <welcome-file>servlet/HomePageServlet</welcome-file> to see if that works, or change servlet mapping to /HomePageServlet.
