Summary

Connecting a Java Server Page (JSP) to a MySQL database requires a straightforward setup process. Developers must first download the MySQL JDBC connector driver and place its JAR file into the Tomcat common lib directory, ensuring it's added to the CLASSPATH. Within the JSP, establish a database connection by loading the JDBC driver, typically com.mysql.jdbc.Driver, and then using DriverManager.getConnection with the appropriate database URL, username, and password. It's crucial to include error handling for connection attempts, and note that org.gjt.mm.mysql.Driver can be used for backward compatibility with older MySQL versions.

To connect MySQL with Java Server Page(JSP). Some steps should be followed:

Step 1: Download MySQL JDBC connector driver from the Internet. URL:  http://dev.mysql.com/downloads/connector/j/

Step 2: Put the jar file downloaded in Step 1 in the Tomcat common lib folder and add this jar file to the CLASSPATH so that the JSP page can find the specified class.

Step 3: Create the JSP page with MySQL connection : Example is shown below:
        <%
String driver="com.mysql.jdbc.Driver";
Class.forName(driver).newInstance();
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;
try{
conn=DriverManager.getConnection("jdbc:mysql://localhost/dbname?user=<username>&password=<password>");
stmt=conn.createStatement();
}catch(Exception e){
System.out.println(e.getMessage());
}
%>

Hope this will help you in your JSP development. One notice is that the driver string can also be "org.gjt.mm.mysql.Driver". This is to make it backward compatible with previous
vsersion of MySQL.
