I'm doing an app for saudi client.My problem is i'm not able to download images at client location.The same code is working out perfectly in my location(India).The only positive thing is XMLs are downloaded at client location.
My Code is like :
HttpConnection c = (HttpConnection) Connector.open(serverUrl+suffix);
c.setRequestMethod(HttpConnection.GET);
c.setRequestProperty("Content-Type", "image/png");
if (c.getResponseCode() == HttpConnection.HTTP_OK) {
is = c.openInputStream();
}else{
return null;
}
Please suggest me any solns.
Thanks & Regards,
Sree Harsha.P
This is Solved.
The code i changed is i returned EncodedImage instead of inputstream from method.
But don't know why returning InputStream from method worked in india and doesn't work in saudi
c = (HttpConnection) Connector.open(serverUrl+suffix);
c.setRequestMethod(HttpConnection.GET);
c.setRequestProperty("Content-Type", "image/png");
if (c.getResponseCode() == HttpConnection.HTTP_OK) {
is = c.openInputStream();
Constants.connectionLength = c.getLength();
int c1;
StringBuffer sb =new StringBuffer();
while( (c1 = is.read()) != -1){
sb.append((char)c1);
}
byte [] b = sb.toString().getBytes();
EncodedImage encodedImage = EncodedImage.createEncodedImage(b, 0, b.length);
return encodedImage;
}else{
return null;
}

I want to get the Bitmap from URL like -
"https://graph.facebook.com/100003506521332/picture"
I tried how-i-can-display-images-from-url-in-blackberry . But its showing http error 302 .It dont showing the Bitmap. How to resolve the problem ?.
String url = "https://graph.facebook.com/100003506521332/picture";
try
{
bitmap = globleDeclaration.getLiveImage(url, 50, 50);
bitmapField.setBitmap(bitmap);
}
catch (IOException e)
{
e.printStackTrace();
Dialog.alert(e.getMessage());
}
public Bitmap getLiveImage(String url,int width,int height) throws IOException
{
Bitmap bitmap = null;
try
{
byte[] responseData = new byte[10000];
int length = 0;
StringBuffer rawResponse = new StringBuffer();
httpconnection = (HttpConnection) Connector.open(url, Connector.READ, true);
String location=httpconnection.getHeaderField("location");
if(location!=null){
httpconnection = (HttpConnection) Connector.open(location, Connector.READ, true);
}else{
httpconnection = (HttpConnection) Connector.open(url, Connector.READ, true);
}
inputStream = httpconnection.openInputStream();
while (-1 != (length = inputStream.read(responseData)))
{
rawResponse.append(new String(responseData, 0, length));
}
int responseCode = httpconnection.getResponseCode();
if (responseCode != HttpConnection.HTTP_OK)
{
throw new IOException("HTTP response code: "
+ responseCode);
}
final String result = rawResponse.toString();
byte[] dataArray = result.getBytes();
encodeImageBitmap = EncodedImage.createEncodedImage(dataArray, 0, dataArray.length);
}
catch (final Exception ex)
{
System.out.print("Exception (" + ex.getClass() + "): " + ex.getMessage());
}
finally
{
try
{
inputStream.close();
inputStream = null;
httpconnection.close();
httpconnection = null;
}
catch(Exception e){}
}
return bitmap;
}
If you done get responce from this code httpconnection = (HttpConnection) Connector.open(url, Connector.READ, true); which is mention in above answer than u can also use alternative solution for that..
You can pass your your id here http://graph.facebook.com/100003506521332/?fields=picture&type=large than you will get one json responce like that {"picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/70678_100003506521332_1415569305_n.jpg"}
parse this json and get which you want exaclty .. than you will get responce using httpconnection = (HttpConnection) Connector.open(url, Connector.READ, true); also .
if you dont want larger image than remove &type=large from the above url.

copy this to your package....
Now, to use this class do like this>>>>>>>>
CREATE BITMAP OBJECT:
Bitmap IMAGE;
After That:
IMAGE=Util_ImageLoader.getImageFromUrl("https://graph.facebook.com/100003506521332/picture");
By the way, I think you have missed extension
like JPG,PNG, on your URL.... Check That
Now, add your bitmap where you would like to display the image......
ENJOY!
add(IMAGE);
I am developing an application in BlackBerry 5.0 and want to display an image from a url. While reading the image from the url using the httpconnection I get the exception "local connection timed out after 120000 "
The exception occurs on the line "httpConnection.getResponseCode()".
My code is as follows :
private byte[] getimagefromurl(String PhotoUrl)
{
String url = "http://www.mywebsite.com/images/Folder/xyz.jpg";
try
{
httpConnection = (HttpConnection) Connector.open(url, Connector.READ_WRITE);
System.out.println("url>>>>>>>> "+url);
httpConnection.setRequestMethod(HttpConnection.GET);
System.out.println("Response>>>>>>>> "+String.valueOf(httpConnection.getResponseCode()));
if(httpConnection.getResponseCode() == HttpConnection.HTTP_OK)
{
InputStream input = httpConnection.openInputStream();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int j = 0;
while((j=input.read()) != -1)
{
baos.write(j);
}
byteArray = baos.toByteArray();
baos.close();
}
}
catch(Exception e)
{
System.out.println("in catch>>>>"+e.toString());
}
return byteArray;
}
append url extension like following example is work when you r working with WIFI
httpConnection = (HttpConnection) Connector.open(url+";interface=wifi", Connector.READ_WRITE);
extensions just check this url
connection extensions
Yes the answer is exactly that. The connection timed out. check that your webservice works. if you are testing from device or emulator ,make sure you can hit the URL from the default blackberry browser.
If you are testing in the emulator, make sure you have MDS-CS simulator started.
have a look at this bit of code which works
import java.io.InputStream;
import javax.microedition.io.Connector;
import javax.microedition.io.StreamConnection;
public class HTTPClient {
public static String getPage(String url) {
String response = "";
try {
StreamConnection s = (StreamConnection)Connector.open(url);
InputStream input = s.openInputStream();
byte[] data = new byte[256];
int len = 0;
StringBuffer raw = new StringBuffer();
while( -1 != (len = input.read(data))) {
raw.append(new String(data, 0, len));
}
response = raw.toString();
input.close();
s.close();
} catch(Exception e) { }
return response;
}
}
I use following code to download jpg image and display in blackberry curve 8900 simulator. When I am trying to load my code, it strucks completely and stop responding. Please some one help me.

Thank you in advance
You need to move the socket code off of the main UI event thread. Your code does the download on the UI thread, meaning no UI responsiveness while downloading the bytes.
i am developing and app for blackberry and i need to send a Http Post Request to my server. I'm using the simulator in order to test my app and i found this code in order to send request:
http://vasudevkamath.techfiz.com/general/posting-data-via-http-from-blackberry/
But i can't get it work, because it fails in this line:
int rc = _httpConnection.getResponseCode();
Any idea?
thanks
Here is a sample code on how to send a POST request:
HttpConnection c = (HttpConnection) Connector.open(url, Connector.READ_WRITE);
c.setRequestMethod(HttpConnection.POST);
OutputStream os = c.openOutputStream();
os.write(request.getBytes("UTF-8"));
os.flush();
os.close();
InputStream is = c.openInputStream();
Just make sure you use this code in a separate thread.
public static ResponseBean sendRequestAndReceiveResponse(String method, String absoluteURL, String bodyData, boolean readResponseBody)
throws IOException
{
ResponseBean responseBean = new ResponseBean();
HttpConnection httpConnection = null;
try
{
String formattedURL = absoluteURL + "deviceside=true;interface=wifi"; // If you are using WiFi
//String formattedURL = absoluteURL + "deviceside=false"; // If you are using BES
//String formattedURL = absoluteURL + "deviceside=true"; // If you are using TCP
if(DeviceInfo.isSimulator()) // if you are using simulator
formattedURL = absoluteURL;
httpConnection = (HttpConnection) Connector.open(formattedURL);
httpConnection.setRequestMethod(method);
if (bodyData != null && bodyData.length() > 0)
{
OutputStream os = httpConnection.openOutputStream();
os.write(bodyData.getBytes("UTF-8"));
}
int responseCode = httpConnection.getResponseCode();
responseBean.setResponseCode(responseCode);
if (readResponseBody)
{
responseBean.setBodyData(readBodyData(httpConnection));
}
}
catch (IOException ex)
{
System.out.println("!!!!!!!!!!!!!!! IOException in NetworkUtil::sendRequestAndReceiveResponse(): " + ex);
throw ex;
}
catch(Exception ex)
{
System.out.println("!!!!!!!!!!!!!!! Exception in NetworkUtil::sendRequestAndReceiveResponse(): " + ex);
throw new IOException(ex.toString());
}
finally
{
if (httpConnection != null)
httpConnection.close();
}
return responseBean;
}
public static StringBuffer readBodyData(HttpConnection httpConnection) throws UnsupportedEncodingException, IOException
{
if(httpConnection == null)
return null;
StringBuffer bodyData = new StringBuffer(256);
InputStream inputStream = httpConnection.openDataInputStream();
byte[] data = new byte[256];
int len = 0;
int size = 0;
while ( -1 != (len = inputStream.read(data)) )
{
bodyData.append(new String(data, 0, len,"UTF-8"));
size += len;
}
if (inputStream != null)
{
inputStream.close();

return bodyData;
}
I know this question is pretty old and OP probably solved it by now, but I've just run into the same problem and managed to fix it!
You need to append ;deviceside=true to your URL.
So for example, your URL will change from "http://example.com/directory/submitpost.php" to "http://example.com/directory/submitpost.php;deviceside=true".
I found this here: http://supportforums.blackberry.com/t5/Java-Development/Different-ways-to-make-an-HTTP-or-socket-connection/ta-p/445879
My POST request was timing out after 3 minutes when I did not have this (See My Comment), but it works fine with this appended to the url.
I would also recommend using ConnectionFactory. Here's some of my code:
Network.httpPost("http://example.com/directory/submitpost.php;deviceside=true", paramNamesArray, paramValsArray)
public static void httpPost(String urlStr, String[] paramName, String[] paramVal) throws Exception {
ConnectionFactory conFactory = new ConnectionFactory();
conFactory.setTimeLimit(1000);
HttpConnection conn = (HttpConnection) conFactory.getConnection(urlStr).getConnection();
conn.setRequestMethod(HttpConnection.POST);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
StringBuffer sb = new StringBuffer();
for (int i = 0; i < paramName.length; i++) {
sb.append(paramName[i]);
sb.append("=");
sb.append(paramVal[i]);
sb.append("&");
}
byte[] postData = sb.toString().getBytes("UTF-8");
conn.setRequestProperty("Content-Length",new Integer(postData.length).toString());
OutputStream out = conn.openOutputStream();
out.write(postData);
//out.flush(); //Throws an Exception for some reason/Doesn't do anything anyways
out.close();
//This writes to our connection and waits for a response
if (conn.getResponseCode() != 200) {
throw new Exception(conn.getResponseMessage());
}
}
Not sure about the site you posted, but I've successfully used the sample ConnectionFactory code provided on the blackberry site.
http://supportforums.blackberry.com/t5/Java-Development/Sample-Code-Using-the-ConnectionFactory-class-in-a-BrowserField/ta-p/532860
Just make sure not to invoke the connection on the EventThread.
That's how you add parameters, Full answer is here:
StringBuffer postData = new StringBuffer();
httpConn = (HttpConnection) Connector.open("https://surveys2.kenexa.com/feedbacksurveyapi/login?");
httpConn.setRequestMethod(HttpConnection.POST);
postData.append("username="+username);

postData.append("&projectcode="+projectid);
String encodedData = postData.toString();
httpConn.setRequestProperty("Content-Language", "en-US");
httpConn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
httpConn.setRequestProperty("Content-Length",(new Integer(encodedData.length())).toString());
byte[] postDataByte = postData.toString().getBytes("UTF-8");
