HTTP Status 500 - Error instantiating servlet class pkg.coreServlet

I am creating simple servlet and deploying it in tomcat server but I am getting the following error:


HTTP Status 500 - Error instantiating servlet class pkg.coreServlet


File Structure on the tomcat server:

webapps
|
- aarya
|
- WEB-INF
|
-web.xml
-src(folder)
|
-pkg
|
-coreServlet.class


web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">


<servlet>
<servlet-name>aaryaservlet</servlet-name>
<servlet-class>pkg.coreServlet</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>aaryaservlet</servlet-name>
<url-pattern>/coreServlet</url-pattern>
</servlet-mapping>
</web-app>


coreServlet.java:

package pkg;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class coreServlet extends HttpServlet
{
/**
*
*/
private static final long serialVersionUID = 1L;

public void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException


{
PrintWriter out = res.getWriter();
res.setContentType("text/html");
out.println("this is First servlet Example ");
}
}


url I am giving is
http://localhost:8080/aarya/coreServlet

I try by restarting tomcat but I am getting same error. Where I am doing wrong?

Answer

Do not put the src folder in the WEB-INF directory!!
