I have my application playing the radio stream which is shoutcast streaming. I have searched on the internet for 2 days but my application stills can't play this url. I don't know how to solve this.
This is my sample source code.
String url1 = "http://203.150.224.142:8003/;
HttpConnection con= (HttpConnection)Connector.open(url1);
InputStream is = con.openInputStream();
player = Manager.createPlayer(is, "audio/mpeg");
player.realize();
player.prefetch();
player.start();
I have used this code in production, it should work for you also.
HttpConnection conn = (HttpConnection) Connector.open(music.getTrack_url() + "?streamable=true", Connector.READ_WRITE);
if (conn.getResponseCode() == HttpConnection.HTTP_OK) {
is = conn.openInputStream();
player = Manager.createPlayer(is, "audio/mp3");
player.addPlayerListener(thisObj);
player.realize();
player.prefetch();
player.start();
}
Try This.
public void loadShoutcast(String url)
{
StreamConnection connection = null;
int BUFFER_SIZE = 1024;
DataOutputStream dos_ = null;
OutputStream os_ = null;
try
{
System.out.println("opening connection " + url);
//Shoutcast URL
connection = (StreamConnection) Connector.open(url);
os_ = connection.openOutputStream();
dos_ = new DataOutputStream(os_);
// send the HTTP request
String req = "GET / HTTP/1.1\r\nUser-Agent: Profile/MIDP-1.0 Configuration/CLDC-1.0\r\n\r\n";
dos_.write(req.getBytes());
is = null;
is = connection.openInputStream();
long byteDone = 0;
int byteCount;
byte[] buffer = new byte[BUFFER_SIZE];
//Connection to file where you want to save the content of shoutcast radio
//It can be skipped in case you dont want to save the contents
out = tempFilecon.openDataOutputStream();
System.out.println("starting download");
while (byteCount = is.read(buffer)) >= 0)
{
out.write(buffer, 0, byteCount);
byteDone += byteCount;
done += byteCount;
}
return;
}
catch (InterruptedIOException e)
{
System.out.println("InterruptedIOException 1" + e.getMessage());
return;
}
catch (Exception e)
{
System.out.println("ERROR - 51 " + e.getMessage());
return;
}
finally
{
if (dos_ != null)
{
dos_.close();
dos_ = null;
}
if (os_ != null)
{
os_.close();
os_ = null;
}
if (is != null)
{
is.close();
is = null;
}
if (out != null)
{
out.close();
out = null;
}
System.out.println("closing connection");
if (connection != null)
{
connection.close();
connection = null;
}
}
// return false;

I'm trying to download an Excel in a liferay portlet but when I'm going to get the outPutPortletStream I obtain the next exception:
java.lang.IllegalStateException: Unable to obtain OutputStream because Writer is already in use
This is the method I'm using to download the Excel:
public static void descargaFichero(ResourceRequest resourceRequest, ResourceResponse resourceResponse) throws Exception {
HttpServletRequest request = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(resourceRequest));
OutputStreamWriter osWriter = null;
BufferedWriter bWriter = null;
OutputStream outputStream = null;
InputStream is = null;
InputStreamReader isr = null;
File tempFile = null;
try {
String idDescarga = request.getParameter("id-descarga");
String rutaFicheroDescarga = Encriptador.decrypt(ConstantesFlujos.CLAVE_ENCRIPTADO_JSON, idDescarga);
String extension = FileUtil.getExtension(rutaFicheroDescarga);
String nombreArchivo = String.format("%s%s.%s",
ConstantesFlujos.PREFIJO_NOMBRE_FICHERO_RENOVACION,
fechaDesglosada(),
extension);
if(GestorLog.isInfoEnabled(clase)){
GestorLog.info(clase, String.format("Descargando fichero temporal: '%s' a '%s'", rutaFicheroDescarga, nombreArchivo));
}
if (extension.equalsIgnoreCase("xls")) {
resourceResponse.setContentType("application/vnd.ms-excel");
} else {
resourceResponse.setContentType("application/octet-stream");
}
((PortletResponse) resourceResponse).addProperty("Content-disposition", String.format("atachment; filename=%s", nombreArchivo));
tempFile = new File(rutaFicheroDescarga);
outputStream = resourceResponse.getPortletOutputStream();
osWriter = new OutputStreamWriter(outputStream, "ISO-8859-1");
char[] buf = new char[8192];
is = new FileInputStream(tempFile);
isr = new InputStreamReader(is, "ISO-8859-1");
int c = 0;
while ((c = isr.read(buf, 0, buf.length)) > 0) {
osWriter.write(buf, 0, c);
osWriter.flush();
}
} catch(Exception e){
GestorLog.error(clase, "Error en el metodo descargaFichero: " + e.getMessage());
throw e;
} finally {
if (isr != null) {
isr.close();
}
if (is != null) {
is.close();
}
if (bWriter != null) {
bWriter.close();
}
if (outputStream != null) {
outputStream.close();
}
if (tempFile != null) {
tempFile.delete();
}
}
}
And I get the error in the line:
outputStream = resourceResponse.getPortletOutputStream();
This might be due to resourceResponse.addProperty being called before accessing the stream. Those operations can be nasty, as two parties will now try to write data to the output.
An easy way to omit all problems is to just delegate it all to the portal: PortletResponseUtil.sendFile exists in a couple of different variations, e.g.
PortletResponseUtil.sendFile(
resourceRequest,
resourceResponse,
fileName,
inputStream,
contentLength,
contentType,
contentDispositionType); // e.g. HttpHeaders.CONTENT_DISPOSITION_ATTACHMENT
HttpConnection c = null;
InputStream is = null;
StringBuffer sb = new StringBuffer();
String request = serverUrl; // + "?loc=" + location.getLat() + "," + location.getLng() + "data=" + message.getString();
try {
c = (HttpConnection) Connector.open("http://www.google.com");
c.setRequestMethod(HttpConnection.GET); //default
is = c.openInputStream(); // transition to connected!
int ch = 0;
for (int ccnt = 0; ccnt < 150; ccnt++) { // get the title.
ch = is.read();
if (ch == -1) {
break;
}
sb.append((char) ch);
return sb.toString();
}
} catch (IOException x) {
x.printStackTrace();
} finally {
try {
is.close();
c.close();
} catch (IOException x) {
x.printStackTrace();
}
}
System.out.println(sb.toString());
return null;
in the above code -- this line
(HttpConnection) Connector.open("http://www.google.com");
does not respond. what can i do to resolve this?
try the following
HttpConnection c = null;
InputStream is = null;
StringBuffer sb = new StringBuffer();
String request = serverUrl; // + "?loc=" + location.getLat() + "," + location.getLng() + "data=" + message.getString();
try {
c = (HttpConnection) Connector.open("http://www.google.com");
c.setRequestMethod(HttpConnection.GET); //default
int status_code=c.getResponseCode();
if(status_code!=HttpConnection.HTTP_OK)
{
//Show the failure message to user
return;
}
//Remaining part is same as your code
In lots of phones, and some simulators, you can only open a connection in another thread. that is to say, if you try to connect in main therad = UI thread it wont work and wont tell you anything. Try simply wrapping your method in a new thread

Highlighted above is the code line which throws the exception: Not Connected.
Can somebody tell me what can be done to correct this? Thanks a lot.

Recently i have started working on consuming wcf rest webservices in blackberry.
I have used the below two codes:

}
but with this code i am unable to obtain response as what the above wcf web service return
which is({"UserRegistrationResult":[{"OutputCode":"2","OutputDescription":"UserName Already Exists."}]})
Can anybody help me regarding its parsing in blackberry client end.
2.And the another code which i used is:
public class KSoapDemo extends MainScreen

private EditField userNametxt;

ex.printStackTrace();
}
return ans;
}
and in return i am obtain response as net.rim.device.cldc.io.dns.DNS Exception:DNS Error
Please help me in this regard
Thanks And Regards

This code works fine on SonyEricsson and Motorola cellphones, but on Nokia it either fails at the beginnig not making any request at all or returns empty response, depending on model.
HttpConnection hc = null;
InputStream is = null;
InputStreamReader isr = null;
String result = "";
try
{
hc = (HttpConnection) Connector.open(url);
int rc = hc.getResponseCode();
if (rc != HttpConnection.HTTP_OK)
{
throw new IOException(hc.getResponseMessage());
}
is = hc.openInputStream();
isr = new InputStreamReader(is, "utf-8");
int ch;
while ((ch = is.read()) != -1)
{
result += (char) ch;
}
}
finally
{
if (is != null)
{
is.close();
}
if (hc != null)
{
hc.close();
}
}
return result;
Tried different codes with byte buffers, streams, etc, result is always the same. What's the problem?

I am not sure if this will work for you but I had a similar problem and found that specifying a port number made it work (on some older Nokia models). i.e convert:
