You need to give Servlet Name in the action do not need to specify anything;
<body>
<h1>Guru Register Form</h1>
<form action="Guru_register" method="post">
//Servlet with annotation
@WebServlet("/Guru_register")
public class Guru_register extends HttpServlet {
private static final long serialVersionUID = 1L;
bro still the same error after adding annotation

HTML engine do not recognize java, that's why we need JSP. With Mapping we give a Servlet a name, a URL and force HTML to identify a Servlet by this particular URL. If you ask HTML tag to identify abc.java it looks in Mapping and it wont identify it.

Try adding servlet info to web.xml
First move your servlet to a package, lets call it 'controllers', so the file's new location would be src > controllers > Guru_register.java
<servlet>
<servlet-name>Guru_register</servlet-name>
<servlet-path>controllers.Guru_register</servlet-path>
</servlet>
<servlet-mapping>
<servlet-name>Guru_register</servlet-name>
<url-pattern>/guru-register</url-pattern>
</servlet-mapping>
Next, modify jsp form as follows:
<form action="guru-register" method="post">
Hi Arvind bro, yeah this is another way right i mean without using annotation this one also would work i assume. thanks for letting me to learn new one
