Get MySQL version with Java

I tested this code to get MySQL version:

public void testMySQLVersion() throws Exception
    {
        System.out.println("\nTesting SQL query for MySQL version\n");

        // Load the JDBC driver
        DriverManager.registerDriver(new oracle.jdbc.OracleDriver());

        // Connect to the database
        Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@112.213.131.40:3306:webdb", "admin", "eHqtaXuc6h1w");

        PreparedStatement pstmt
            = conn.prepareStatement("SHOW VARIABLES LIKE 'version'");

        ResultSet rset = pstmt.executeQuery();

        while (rset.next())
        {
            System.out.println("MySQL version " + rset.getString("Value"));
        }

        pstmt.close();
        conn.close();
    }

But I get this result when I run the code:

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.634 sec <<< FAILURE! - in org.mysql.engine.osgi.impl.MySQLImplTest

Can you give me some advice how to solve this issue?
