My DB2 database version is 11.1 and my java code to connect to DB2 is -

public static Connection getConnection() {

        Properties prop = LoadProperties.getProperties();
        logger.info("Properties From Property File : ");
        logger.info("DB2Driver : "+prop.getProperty("DB2Driver"));
        logger.info("DB2ConnectionURL : "+prop.getProperty("DB2ConnectionURL"));
        logger.info("DB2UserName : "+prop.getProperty("DB2UserName"));
        logger.info("DB2Password : "+prop.getProperty("DB2Password"));

        Connection connection = null;
        try {

            Class.forName(prop.getProperty("DB2Driver"));
            connection = DriverManager.getConnection(prop.getProperty("DB2ConnectionURL"), 
                                                     prop.getProperty("DB2UserName"), 
                                                     prop.getProperty("DB2Password"));

            if(connection != null) {
                System.out.println("Connected successfully.");
            } else {
                System.out.println("Colud not Connect successfully.");
            }

        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } 

        return connection;
    }

I have below-given jar files in my project.

Can anyone please help me in knowing why this exception is coming and what is the solution?

Per comment thread, it was a change to the properties file .

The correct class name should be com.ibm.db2.jcc.DB2Driver
