What are session and cookies in Java Server Pages (JSP)?

Balmukund replied | 3 days ago

  • Session: Stores user data on the server while the user is logged in.
    Example: session.setAttribute("username", "John");
  • Cookie: Stores small pieces of data in the user's browser.
    Example: remembering username or login preferences.

In short: Session = server-side, Cookie = client/browser-side.

What is JSP file format in Java programs and how to use them?

0 0

Balmukund replied | 3 days ago

JSP = Java Server Page (.jsp) used to create web pages.

  • JSP → UI / HTML
  • Servlet → Java logic
  • JDBC → Database connection

Example:

<h2>Hello <%= username %></h2>

Typical flow:

login.jsp → LoginServlet.java → Database → home.jsp

How do I create a login page in Java using servlets and JSP?

0 0

Balmukund replied | 3 days ago

Java Servlet + JSP Login Flow

login.jsp
   ↓
LoginServlet
   ↓
Check username/password in MySQL
   ↓
Valid? ── Yes → Create HttpSession → home.jsp
   │
   └── No → Back to login.jsp with error

Main components

  • JSP → Login form/UI
  • Servlet → Handles login request
  • JDBC → Connects Java to MySQL
  • MySQL → Stores users
  • HttpSession → Keeps user logged in
  • Logout Servlet → Invalidates session

For a real project, use BCrypt/password hashing, not plain-text passwords.

Maths teaches you how to calculate. Physics teaches you what to calculate, why to calculate it and how it applies to the real world.

Satya Tripathi replied | 2 days ago

Physics feels harder than math bcoz math gives you the rules,but physics forces you to apply them to the messy real world
