This document provides an overview of JSP, JDBC, and ODBC, and how to connect to a MySQL database from a Java application using JDBC. It explains that JDBC is an API that defines how Java applications access databases, and it works with both relational and ODBC databases. It then demonstrates how to load the MySQL JDBC driver, define the connection URL, establish a connection, and create a statement object to execute queries.

1. JSP to create usable apps.
A fun way
+ MySQL

2. THE BASICS
• What is JSP?
• What is JDBC?
• What is ODBC?

3. What Exactly is JDBC?
• JDBC is an API for the Java programming language that defines how a
client may access a database. It provides methods for querying and
updating data in a database. JDBC is oriented towards relational
databases.
Servlet
JDBC
ODBC DB

4. How do we do that???

5. Loading the JDBC Driver
• We should have the Driver!!!
• MySQL Connector/J - version 2 used for this tutorial
Download Link : http://dev.mysql.com/downloads/connector/j/
• Copy it to the “lib” folder in the server.

6. Loading the JDBC Driver
• To load the driver you only need to load the appropriate class.
• Syntax : Class.forName(“fully qualified class name”)
• For MySQL : Class.forName(“com.mysql.jdbc.driver”)

7. Defining the connection URL
• Driver is ready to go..But where???
• Define a connection URL which specifies the
SERVER & the Database needed
• “jdbc:mysql://localhost:3306/db_name”

8. Establishing the connection
• The actual network connection!!
• Connection conn=DriverManager.getConnection(“Connection URL”,”user”,”pass”);

9. Creating the statement Object
• Statement stmt = conn.createStatement();
• Statement Object sends queries and commands to the database.

10. HOW EXACTLY DOES ALL THIS WORK???
