POHttp Post with Blackberry 6.0 issue
text
Body
copied!<p>I am trying to post some data to our webservice(written in c#) and get the response. The response is in JSON format.</p> <p>I am using the Blackberry Code Sample which is BlockingSenderDestination Sample. When I request a page it returns with no problem. But when I send my data to our webservice it does not return anything. </p> <p>The code part that I added is : </p> <pre><code>ByteMessage myMsg = bsd.createByteMessage(); //myMsg.setStringPayload("I love my BlackBerry device!"); myMsg.setMessageProperty("querytpe","myspecialkey");//here is my post data myMsg.setMessageProperty("uname","myusername"); myMsg.setMessageProperty("pass","password"); ((HttpMessage) myMsg).setMethod(HttpMessage.POST); // Send message and wait for response myMsg response = bsd.sendReceive(myMsg); </code></pre> <p>What am i doing wrong? And what is the alternatives or more efficients way to do Post with Blackberry.</p> <p>Regards.</p> <p>Here is my whole code:</p> <pre><code>class BlockingSenderSample extends MainScreen implements FieldChangeListener { ButtonField _btnBlock = new ButtonField(Field.FIELD_HCENTER); private static UiApplication _app = UiApplication.getUiApplication(); private String _result; public BlockingSenderSample() { _btnBlock.setChangeListener(this); _btnBlock.setLabel("Fetch page"); add(_btnBlock); } public void fieldChanged(Field button, int unused) { if(button == _btnBlock) { Thread t = new Thread(new Runnable() { public void run() { Message response = null; String uriStr = "http://192.168.1.250/mobileServiceOrjinal.aspx"; //our webservice address //String uriStr = "http://www.blackberry.com"; BlockingSenderDestination bsd = null; try { bsd = (BlockingSenderDestination) DestinationFactory.getSenderDestination ("name", URI.create(uriStr));//name for context is name. is it true? if(bsd == null) { bsd = DestinationFactory.createBlockingSenderDestination (new Context("ender"), URI.create(uriStr) ); } //Dialog.inform( "1" ); ByteMessage myMsg = bsd.createByteMessage(); //myMsg.setStringPayload("I love my BlackBerry device!"); myMsg.setMessageProperty("querytpe","myspecialkey");//here is my post data myMsg.setMessageProperty("uname","myusername"); myMsg.setMessageProperty("pass","password"); ((HttpMessage) myMsg).setMethod(HttpMessage.POST); // Send message and wait for response myMsg response = bsd.sendReceive(myMsg); if(response != null) { BSDResponse(response); } } catch(Exception e) { //Dialog.inform( "ex" ); // process the error } finally { if(bsd != null) { bsd.release(); } } } }); t.start(); } } private void BSDResponse(Message msg) { if (msg instanceof ByteMessage) { ByteMessage reply = (ByteMessage) msg; _result = (String) reply.getStringPayload(); } else if(msg instanceof StreamMessage) { StreamMessage reply = (StreamMessage) msg; InputStream is = reply.getStreamPayload(); byte[] data = null; try { data = net.rim.device.api.io.IOUtilities.streamToBytes(is); } catch (IOException e) { // process the error } if(data != null) { _result = new String(data); } } _app.invokeLater(new Runnable() { public void run() { _app.pushScreen(new HTTPOutputScreen(_result)); } }); } } </code></pre> <p>..</p> <pre><code>class HTTPOutputScreen extends MainScreen { RichTextField _rtfOutput = new RichTextField(); public HTTPOutputScreen(String message) { _rtfOutput.setText("Retrieving data. Please wait..."); add(_rtfOutput); showContents(message); } // After the data has been retrieved, display it public void showContents(final String result) { UiApplication.getUiApplication().invokeLater(new Runnable() { public void run() { _rtfOutput.setText(result); } }); } } </code></pre>
