I had written the program JDBCConnection. i.e.,
Here admin is mysql password.
public class Connect
public static void main (String args)
Connection conn = null;
String userName = "Root";
String password = "admin";
String url = "jdbc:mysql://localhost:3306/test";
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url,userName ,password );
System.out.println ("Database connection established");
catch (Exception e)
System.err.println ("Cannot connect to database server");
I had copied the mysql-connector-java-5.0.8-bin.jar file in the location of C:\Program Files\Java\jdk1.5.0\jre\lib folder and set the class path as same path.
When i had compile the program it has compile successfully. But when i was runeed it has displayed an error message.
Exception in thread "main" java.lang.NoClassDefFoundError: Connect
Please tell me what is the mistake any one knows.
