I was having the following error: java.sql.SQLException: Cannot create PoolableConnectionFactory (Cannot open file:C:\AppServers\glassfish5\glassfish\domains\domain1/config/keystore.jks [Keystore was tampered with, or password was incorrect])
Solved it by simply adding useSSL=false on MySQL database connection and JDBC_URL String in class DBConnection.
Database Connection
package data;
import java.sql.*;
import javax.sql.DataSource;
import org.apache.commons.dbcp2.BasicDataSource;
public class DBConnection {
private static final String JDBC_URL = "jdbc:mysql://localhost:3306/course_management_system?zeroDateTimeBehavior=CONVERT_TO_NULL&useTimezone=true&serverTimezone=UTC";
private static final String JDBC_USER = "root";
private static final String JDBC_PASSWORD = "admin";
private static BasicDataSource dataSource;
public static DataSource getDataSource() {
if (dataSource == null) {
dataSource = new BasicDataSource();
dataSource.setUrl(JDBC_URL);
dataSource.setUsername(JDBC_USER);
dataSource.setPassword(JDBC_PASSWORD);
dataSource.setInitialSize(50);
try {
Class.forName("com.mysql.cj.jdbc.Driver");
} catch (ClassNotFoundException ex) {
ex.printStackTrace(System.out);
}
}
return dataSource;
}
public static Connection getConnection() throws SQLException {
return getDataSource().getConnection();
}
public static void close(ResultSet rs) {
try {
rs.close();
} catch (SQLException ex) {
ex.printStackTrace(System.out);
}
}
public static void close(PreparedStatement stmt) {
try {
stmt.close();
} catch (SQLException ex) {
ex.printStackTrace(System.out);
}
}
public static void close(Connection conn) {
try {
conn.close();
} catch (SQLException ex) {
ex.printStackTrace(System.out);
}
}
}

SOLUTION
I solved the issue adding useSSL=false to the DB Connection string.
I solve the problem by adding useSSL=false in the database URL.
