This project is for creating a simple site with Java and vertx-web.
http://vertx.io/ vertx is a high performance library with async features.
Creating a basic system is the project. Even If you don't have experience in vertx, you can learn the latest features through this project.
1) create a table with mysql for user. basic data for user.
2) login,register,logout,reset password by sending url,update email by sending url.
3) user page is required with showing gravatar icon, username, profile.
4) crud admin page for editing users.
5) use bootstrap or material design 's simple css. you can use default or your edition.
I hope this can be done within 3 weeks.
Programming with vertx may be very fun.
