Interactive Broker Java API returns nothing from historicalData

Supposed the below code would returns and print a list of historical market data like the open, close, high, low, volume. The connection to Interactive Broker API should be fine. But in Java console, it did not print the market data from callbacks. Looks like it did not go through the historicalData function. How do I activate that function and store the market data in an object?

Sample Code:

    void run() {
        m_client.eConnect("localhost", 7497, 123);
        final EReader reader = new EReader(m_client, m_signal);
        reader.start();
        new Thread() {
            @Override
            public void run() {
                while (m_client.isConnected()) {
                    m_signal.waitForSignal();
                    try {
                        reader.processMsgs();
                    } catch (Exception e) {
                        System.out.println("Exception: " + e.getMessage());
                    }
                }
            }
        }.start();
        
        try {
			Thread.sleep(1000);
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
    }

    @Override
    public void nextValidId(int orderId) {
        System.out.println("id "+orderId);
        nextOrderID = orderId;
        //Contract c = new StkContract("AAPL");
        Contract c = new Contract();
        c.symbol("EUR");
        c.exchange("IDEALPRO");
        c.secType("CASH");
        c.currency("USD");
        
        m_client.reqHistoricalData(1, c, 
        		LocalDate.now().format(DateTimeFormatter.BASIC_ISO_DATE)+ " 16:00:00",
                "1 D", "1 min", "MIDPOINT", 1, 1, false, null);
        m_client.reqMktData(1, c, "", false, false, null);
    }

    @Override
    public void error(int id, int errorCode, String errorMsg) {
        System.out.println(id + " " + errorCode + " " + errorMsg);
    }

    @Override
    public void historicalData(int reqId, String date, double open, double high, double low, double close, int volume, int count, double WAP, boolean hasGaps) {
        //if being run on the next calendar day, this works
        if (LocalDate.now().minusDays(1).format(DateTimeFormatter.BASIC_ISO_DATE).equals(date)){
            this.date = date;
        	this.high = high;
            this.low = low;
            this.open = open;
            this.close = close;
            System.out.println(date + " h: " + high + " l: " +low);
        }
        System.out.println("Requesting Data...");
        System.out.println(EWrapperMsgGenerator.historicalData(reqId, date, open, high, low, close, volume, count, WAP));
        System.out.println("Data Input Ended...");
    }
