Thansk for the explain the but i got a error, "Error instantiating servlet class [sendemail.Userverify]" the discription is "The server encountered an unexpected condition that prevented it from fulfilling the request." can any one tell how to resolve this error? can u tell me sir?
For those who are getting this error '535 Authentication credentials invalid' write: pr.setProperty("mail.smtp.host", "smtp.gmail.com"); instead of : pr.setProperty("mail.smtp.host", "smtp.mail.com"); if you're using a google account for sending the code. It will work!
Yes, actually request dispatcher only work on requested scope. It’s work on limited area. But session is global. In verify page we are hitting our form to new servlet. And there you can’t access the request scope value you have set in previous servlet.
Dear Sir Thank you for this wonderful tutorial. I have one request, can you please make one video for below program - How to send mail to particular user based upon document expiry date using Java JSP Servlet. For Example I have written small code to upload file into Mysql database. File can be doc, excel, pdf and so on. While uploading document i have given Validity From Date and Validity End Date. Before expiration of document, mail should sent to user like your this this document is going to expire in suppose 5 days. So how to implement this
I have one more question jaja, sorry, Why do I need to use a new Authenticator in 19:39 ?, I have set it null and it works fine. I think that authentication is used to avoid a kind of authorization, idk
i follow your steps but when i run the project i got this message"Failed to send verification email " and i don't receive any email.Could you please help me with this

Glad to hear that it helps you☺️
U save my life, thanks
You are welcome 🥰
Did exactly everything you've shown in the video... But when I click on Register I'm not getting any output why is that?
if you use gmail for security reason you won't get email
For those who are getting this error '535 Authentication credentials invalid'
write: pr.setProperty("mail.smtp.host", "smtp.gmail.com");
instead of : pr.setProperty("mail.smtp.host", "smtp.mail.com");
if you're using a google account for sending the code.
It will work!
It’s google security issue.
why are you retrieving the session 26:56?, you can do it with getRequestDispatcher("/verify.jsp").forward(request, response); no?
Yes, actually request dispatcher only work on requested scope. It’s work on limited area. But session is global. In verify page we are hitting our form to new servlet. And there you can’t access the request scope value you have set in previous servlet.
@@TechTutorialCN Oh! Really can't reach the previous value? I wanna test it :D, thanks for reply !
