J2EE做的網站，要訪問其他網站

就出現以下異常：
javax.net.ssl.SSLProtocolException: handshake alert: unrecognized_name

嘗試照網上說的添加： **System.setProperty("jsse.enableSNIExtension", "false");**
但是無效。

以下是我的代碼。該方法在Capture類中，servlet類中調用Capture類的方法，方法代碼如下：
private double[] getPosition(double lat, double lon) throws Exception
{

    System.setProperty("jsse.enableSNIExtension", "false");
    String strURL = "https://eosweb.larc.nasa.gov/cgi-bin/sse/grid.cgi?&num=230000&lat=" + lat + 
            "&submit=Submit&veg=17&p=swv_dwn&step=2&lon=" + lon;
    //"https://eosweb.larc.nasa.gov/cgi-bin/sse/grid.cgi?&num=199997&lat=" + lat + "&submit=Submit&veg=17&p=swv_dwn&step=2&lon=" + lon;

    URL url = new URL(strURL);
    HttpURLConnection httpConn =  (HttpURLConnection) url.openConnection();

    InputStreamReader input = new InputStreamReader(httpConn.getInputStream(), "utf-8");
    BufferedReader bufReader = new BufferedReader(input);
    StringBuilder contentBuf = new StringBuilder();
    String line = "";
    while((line = bufReader.readLine()) != null) {
        contentBuf.append(line);
    }

    String buf = contentBuf.toString();
    int beginIx = buf.indexOf("year Average");
    int endIx = buf.indexOf("Minimum And Maximum Difference");
    String resultstr = buf.substring(beginIx, endIx);

    return getDoubles(resultstr);
}
