How to prevent Error 500: javax.servlet.ServletException: Servlet initialization has
Hello
This is the First Time i got following error when logging and operating the website
"Error 500: javax.servlet.ServletException: Servlet initialization has failed"
Although my form has webview2 object and very often i operate the exe file with webview2.
As the Error poped up then i thought of operating the same by google Chrome and From MS -Edge the website, everything went smooth and normal with login and password.
My doubt why not similar type of above error is seen when operating a website thru search engines like MS-Edge and Google Chrome.
How can i prevent the error ?
Secondly My MS-Edge does not closes down properly when Clicking on X.
I tried nearly all the solutions available on net but still not able to close MS Edge.
Your help will be appreciated ?
