I'm new to NetBeans and JSP Servlet and I'm trying to create a Web Application using JSP Servlet in Apache NetBeans 11.1 and I keep getting this error:
HTTP Status 500 – Internal Server Error
Type Exception Report
Message Error instantiating servlet class [controller.NewServlet]
Description The server encountered an unexpected condition that prevented it from fulfilling the request.
Exception
javax.servlet.ServletException: Error instantiating servlet class [controller.NewServlet]
org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:490)
I tried uninstalling Netbeans and Tomcat server and reinstall them but still, got the same error.
This is what my Web.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>

My problem is not same as this (HTTP Status 500 - Error instantiating servlet class pkg.coreServlet) because My src folder is not in the WEB-INF directory.
Can someone please help me with this, I don't know what am I missing or doing wrong. I'm using macOS Catalina, got the same error while using the previous version of Mac as well.
