Build a JSP site

I would like a website for Erasmus Buddy Finder. So it is just a site for students that go to another country with erasmus and they need someone to pick them up and help them figure out stuff. It needs to be in Java JSP , you can only do it in .jsp files(java code in html), there is no need for use of servlets. You can use bootstrap for responsive css. I have thinked of it like this. The admin takes a list of succeeding students from the university and registers [login to view URL] database consists of USERS which they are ADMINS , BUDDIES , STUDENTS. USERS Attributes-> name , surname , username-unique,type(buddy,admin,student), pass, email USERS functions-> Change pass, Log in Log Out Admin Functions-> Create Buddy/Student/Admin (He registers everyone by taking a list of succeeding students with erasmus+ program from the university), View Buddy Applicants, Send email to students with password and username Buddy Functions -> View arrival and info of students, Filter arrivals(e.g. Since 10/3 - 13/3) Student attributes-> photo Student Functions->Edit profil (photo , info , email, arrival etc..) WEB STRUCTURE CAN BE LIKE THIS: 1)[login to view URL] with log in(UN,PASS) , AND button to redirect to sign up for buddy program 2)[login to view URL] (Buddy account will be created from an Admin like students if accepted) 3)[login to view URL] -> it has a log out button + change password . It shows different forms for different type of user. If we have a studdent in session then he can just edit his photo , a text with info about him and change password and thats it. if we have a buddy , he can view arrivals and student information and filter them. if we have an admin then he needs create user and view buddy applicants 4)[login to view URL] 5)[login to view URL] Until 27 september . Photo shows what we are talking above.
