Unable to establish the connection to the file in BlackBerry
- by Vikas
I have tried the example code on SO to read the contents from the file in the resource directory in BlackBerry. But I am having an issue with the FileConnection. I get the following error:
File system error (1003)
I tried the example from here. I want only the read functionality, the file I want to read is in CSV format as a .txt file placed in the /res/test.txt.
public class FileDemo extends MainScreen {
public FileDemo() {
setTitle("My Page");
String str = readTextFile("file:///test.txt");
System.out.println("Contents of the file::::::: " + str);
}
public String readTextFile(String fName) {
String result = null;
FileConnection fconn = null;
DataInputStream is = null;
try {
fconn = (FileConnection) Connector.openInputStream(fName);
is = fconn.openDataInputStream();
byte[] data = IOUtilities.streamToBytes(is);
result = new String(data);
} catch (IOException e) {
System.out.println(e.getMessage());
} finally {
try {
if (null != is)
is.close();
if (null != fconn)
fconn.close();
} catch (IOException e) {
System.out.println(e.getMessage());
}
}
return result;
}
}
Any suggestions/advice on a better approach or as to how I can get this working??
