    <p>I have pasted a code snippet for HTTP Post where I am POSTING a multipart message to the server which needs Authentication. I am expecting a JSON response, but when I run this I always get the login page in HTML.</p> <pre><code>public final class MyScreen extends MainScreen { private RichTextField _Output; public MyScreen() { // Set the displayed title of the screen setTitle("MyTitle"); _Output = new RichTextField(); add(_Output); addMenuItem(_GetDataAction); } protected MenuItem _GetDataAction = new MenuItem("GetData", 100000, 10) { public void run() { String URL = "&lt;Sample URL Goes Here&gt;"; ServiceRequestThread svc = new ServiceRequestThread(URL, (MyScreen) UiApplication.getUiApplication() .getActiveScreen()); svc.start(); } }; public void updateDestination(final String text) { UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { _Output.setText(text); } }); } } class ServiceRequestThread extends Thread { protected String _URL; protected MyScreen _Dest = null; protected URLEncodedPostData _PostData = null; StringBuffer writer = new StringBuffer(); public void setPOSTData(URLEncodedPostData data) { _PostData = data; } public ServiceRequestThread(String URL, MyScreen screen) { super(); _Dest = screen; _URL = URL; } public void run() { try { String boundary = "SATBA"; String twoHyphens = "--"; String data1 = "{\"IMPORTING\":{ \"IN_COUNTRY_CODE\":\"US\"}}"; String CRLF = "\r\n"; byte[] encoded = Base64OutputStream.encode ("User:password".getBytes(), 0, "User:password".length(), false,false); "Prepare the data for post" writer.append("--" + boundary).append(CRLF); writer.append("Content-Disposition: form-data; name=\"param\"").append( CRLF); writer.append("Content-Type: text/json; charset=" + "UTF-8").append(CRLF); writer.append("Content-Transfer-Encoding: 8bit").append(CRLF); writer.append("Request-Id:Abcd123456" ).append(CRLF); writer.append("Request-Type:rfc_json").append(CRLF); writer.append("function:00163E0136C01EE0AE8B059433A71727") .append(CRLF); writer.append(CRLF); writer.append(data1).append(CRLF); writer.append("--" + boundary + "--").append(CRLF); String string = new String(writer); HttpConnection conn1 = (HttpConnection)Connector.open(_URL,Connector.READ_WRITE); conn1.setRequestMethod(HttpConnection.POST); conn1.setRequestProperty("Authorization", "Basic "+ new String(encoded)); conn1.setRequestProperty("Content-Type","multipart/mixed; boundary=" + boundary); OutputStreamWriter osw = new OutputStreamWriter(conn1.openOutputStream(), "UTF-8"); osw.write(string); osw.flush(); osw.close(); int responseCode = conn1.getResponseCode(); if (responseCode == HttpConnection.HTTP_OK) { InputStream data = conn1.openInputStream(); StringBuffer raw = new StringBuffer(); byte[] buf = new byte[4096]; int nRead = data.read(buf); while (nRead &gt; 0) { raw.append(new String(buf, 0, nRead)); nRead = data.read(buf); } _Dest.updateDestination(raw.toString()); } else { _Dest.updateDestination("responseCode=" + Integer.toString(responseCode)); } } catch( IOException e) { e.printStackTrace(); _Dest.updateDestination("Exception:"+e.toString()); } } } </code></pre>

    1. COWithout telling us the actual URL (for *most* urls, a HTTP response is expected and normal), you can't expect us to help. At least tell us what the page reply is supposed to look like, and what kind of request its provider claims will elicit the JSON response you want.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
