Posting variable from java application to PHP

Question

I am building a java application using Netbeans, I want to create a JButton to post a value from my application to a php file. I am applying the following code and it is not working:

private void jButton5ActionPerformed(java.awt.event.ActionEvent evt) {                                         

 try{
HttpClient httpclient = HttpClients.createDefault();
HttpPost httppost = new HttpPost("http://localhost/blow.php/");

List<NameValuePair> params = new ArrayList<NameValuePair>(2);
params.add(new BasicNameValuePair("date", "12/11/2016"));

httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

//Execute and get the response.
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

if (entity != null) {
    InputStream instream = entity.getContent();
    try {
        // do something useful
    } finally {
        instream.close();
    }
}
        }catch(Exception w){
            System.err.println(w);}
// open file location and check 
String FolderName="http:\\localhost/blow.php";//Write your complete path here
try {
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + FolderName);
    } catch (IOException ex) {
          Logger.getLogger(blowing.class.getName()).log(Level.SEVERE, null, ex);
    }      


    }

and in the php file only this is written:

 <?php

   $da=$_POST['date'];
   echo $da;

 ?>

Can you help with this please, thanks

I think you have a typo in String FolderName="http:\\localhost/blow.php";//Write your complete path here it should be http:\\localhost/blow.php with slashes — uylmz, Dec 13 '16 at 17:56
the php file location is running it opens in the browser but there is no POST received — S.Abed, Dec 13 '16 at 17:59
What is your intent with the second part of your code? (part that deals with `Runtime.getRuntime().exec(...)`). What is the expected result? — Ceredig, Dec 14 '16 at 08:30
First part posts the data to php; php echos the value `date` back in its response. But nothing is actually done with the response. — Ceredig, Dec 14 '16 at 08:33
Also: How can you tell that on POST is received? (wireshark traces? php server logs?, etc...). What are the symptoms? — Ceredig, Dec 14 '16 at 08:34
