Why does the below 'System.out.println'(fileEncodedString) display a blank line while the value is there when I debug and I do get an output when I decode the value and print.
byte[] fileContent = readFileToByteArray(filePath);
String fileEncodedString = Base64.getEncoder().encodeToString(fileContent);
byte[] fileDecodedString = Base64.getDecoder().decode(fileEncodedString);
System.out.println("Base64 Decoded File (Basic): " + new String(fileDecodedString, "utf-8"));
private static byte[] readFileToByteArray(String filePath) {
FileInputStream fileInputStream = null;
byte[] bytesArray = null;
try {
File file = new File(filePath);
bytesArray = new byte[(int) file.length()];
// read file into bytes[]
fileInputStream = new FileInputStream(file);
fileInputStream.read(bytesArray);
} catch (IOException e) {
e.printStackTrace();
} finally {
if (fileInputStream != null) {
try {
fileInputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return bytesArray;
}
Try to use below method for readFileToByteArray and pass correct file path:
static byte[] readFileToByteArray(String filePath) throws IOException {
File file = new File(filePath);
return Files.readAllBytes(file.toPath());
}
its working fine.
i am facing a issue on getting JObject, my app is working in emulator and it is not working in device. because the string is not properly converting to JObject.

I'm trying to send a file from my Windows machine to my Raspberry-Pi 2, and I have a client and a server. The client should be able to send a zip file over the network to my server on my linux machine. I know my client and server work on Windows, as when I run both the client and server on windows and connect using 127.0.0.1 it works perfectly. But when sending it to my Pi, nothing gets sent over the socket. Any suggestion?

Your problem is here. You can't use multiple inputs on a socket when one or more of them is buffered. The buffered input stream/reader will read-ahead and 'steal' data from the other stream. You need to change your protocol so you can use the same stream for the life of the socket at both ends. For example, use DataInputStream, with readUTF() for the file name and read() for the data: at the sender, use DataOutputStream, with writeUTF() for the filename and write() for the data.
Recently i have started working on consuming wcf rest webservices in blackberry.
I have used the below two codes:
1.
URLEncodedPostData postData = new URLEncodedPostData(URLEncodedPostData.DEFAULT_CHARSET, false);
// passing q’s value and ie’s value
postData.append("UserName", "hsharma#seasiaconsulting.com");

}
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

}
catch (XmlPullParserException ex) {

ex.printStackTrace();
} catch (IOException ex) {
add(new LabelField("ex1 "+ex.toString()) );
ex.printStackTrace();
} catch (Exception ex) {
add(new LabelField("ex1 "+ex.toString()) );
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

I am new to J2ME and now I have to solve one J2ME project.
Below is my login form I don't know what to do with that but it is giving me the error "javax.microedition.io.ConnectionNotFoundException: TCP open". After searching on the google I got some hint that we have to run the code on "OTA Provisioning option ".
Now I don't know how to do that. I have "Version 2.5.2 for CLDC" of WTK. Can anybody suggest me on that?
