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 will upload it as soon as possible.
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
Fail to send verification code
Every thing I review exactly same ur explain
Also less secure app
I was changed it
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.
I have one question, Why you did not map servlet in Web.xml file Please Reply
It’s do automatically or if you use annotations you don’t need to do configure web.xml file
@@TechTutorialCN Thank You, Actually, I use eclipse and in eclipse, we have to map every single servlet to the web.xml manually. that's why I asked
@@TechTutorialCN Hello Can you please upload a video about How to set Cookie on the client-side so that they do not need to login all-time
like Remember me Using JSP and SERVLET
@@SansaniKhabarlive hmm you can do it in two ways using cookies or local storage. I will try to upload it in my free time.
@@TechTutorialCN if I pay you then can you please teach me JSP, servlet, JDBC

i want use jakarta than javax, because i want integrated send email to my other project
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
Yes it should work. Actually it’s return session which is helpful for debugging.
U save my life, thanks
You are welcome 🥰
Sir when I use getCode() its showing it is undefined for the type User. Please help
Please check out the user class getters and setters method. Also double-check you set the code value properly.
OTP stored in database but not send to gmai......and shows also null pointer exception
Gmail has security issue to get smtp access from outside.
@@TechTutorialCN so sir what we do for that....
You can try other email services. Or from a free host service take a free webmail to use it your test project.

how to send email verification link using java servlet
Generate a has string store them in database. Then send the has to email. Validate the has on get request.
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 !

What error you are getting?
@@TechTutorialCN It is about the gmail, but i fixed it. Thank you for the video
Mình cũng đang gặp vấn đề không gửi đc email. B có thể chỉ mình cách bạn đã khắc phục được k?
@@hnhschannel2116 b kéo xuống bên cmt dưới có người chỉ lỗi 535 hay gì gì đó mà sửa mail thành gmail ấy. Vẫn chưa được nữa thì do gg nó không cho bật cái less secure app access, nên ko gửi được. Mình phải dùng mail edu thì mới gửi đc mail đi.
Mình cũng bị giống bạn, bạn đã làm được chưa ? có thể giúp mình được hk ?
Thanks for this great tutorial, it is god sends 🙏
I am really glad to hear from you.
@@TechTutorialCN Thanks, your source code didn't put gmail as a host property for the SMTP. :)
@@wpatyune1631 for gmail host property is "smtp.gmail.com" and smtp.port and socketfactory.port is 465. and don't forget to turn off two-step verification and less secure app.

you may use gmail app-password instead of using your original password.
@@TechTutorialCN @TechTutorial Hi there, I used mail.com like you did in the tutorial. Not gmail ?
Please double check the password and port
