How to detect first time login to the web application

[dmane]

Hi,

I have developed a web application using struts 2 framework . I want to generate a password automatically on first time log in to the application and send a notification mail with new password and a link to change that password. How to detect the first time log in of the user?

Hi,
If u use the emailaddress as username which is unique, so that u can check in the database immediately by lossing the focus from the textfield and write a logic as if not exists , you need to generate password,send it to the entered email and update the database.

Normally in most of the cases, initial logins are logged separately in a database. And that information use in future. Based on the you can build different logic.

For example, think you've a user table and you've maintain a status there to identify the initial login. From that initial login what you are really doing it sent a mail with the confirmation URL, and on top of that url you can update the status. Normally you're not given a password to the user, he/she could use a one and you keep it as the login password to your application.
