Question

I tried the example from “J2ME/Blackberry – how to read/write text file?”. 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.

But I am having an issue with the FileConnection. I get the following error:

File system error (1003)

Any suggestions or advice on a better approach or as to how I can get this working?

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;
}
}

try this

InputStream is = getClass().getResourceAsStream("/test.txt");
StringBuffer buff = new StringBuffer();
int ch;
try {
    while ((ch = is.read()) != -1)
    buff.append((char) ch);
} catch (Exception e) {
    Log.Error(e, "Exception ");
}
String str = (buff.toString());
