I am trying to make an applicatio in java which has database in mysql. I have searched various sources on net and have included mysql-connector-java-5.0.8-bin.jar
in properties->library->add JAR/Library.
But it still shows me java.lang.ClassNotFound Exception
when i run it.
I am using netbeans IDE 8.0 and jdk 1.7.0_45 and mysql server 5.6
Here is my code for jdbc mysql connection:
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
System.out.println("Connecting to a selected database...");
con = DriverManager.getConnection("jdbc:mysql://localhost/prj","root","root");
System.out.println("Connected database successfully...");
s=con.createStatement();
String q="insert into call_log"+" values(now(),'room 1')";
s.executeUpdate(q);
} catch(SQLException se) {
se.printStackTrace();
} catch(Exception e) {
System.out.println(e);
} finally {
try {
if(con!=null)
con.close();
} catch(SQLException se) {
se.printStackTrace();
}
}
This code is working in NetBeans 8.0.2
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.logging.Level;
import java.util.logging.Logger;
public class DBConnect {
public static void main(String[] args) {
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
System.out.println("Connecting to a selected database...");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/mydb", "user", "pass");
System.out.println("Connected database successfully...");
Statement s = con.createStatement();
String q = "select * from table";
s.execute(q);
} catch (ClassNotFoundException | SQLException | InstantiationException | IllegalAccessException ex) {
Logger.getLogger(DBConnect.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
