Hi, I have a config.properties file at the root of my blackberry project (same place as Blackberry_App_Descriptor.xml file), and I try to access the file to read and write into it. See below my class:
public class Configuration {
private String file;
private String fileName;
public Configuration(String pathToFile) {
this.fileName = pathToFile;
try {
// Try to load the file and read it
System.out.println("---------- Start to read the file");
file = readFile(fileName);
System.out.println("---------- Property file:");
System.out.println(file);
} catch (Exception e) {
System.out.println("---------- Error reading file");
System.out.println(e.getMessage());
}
}
/**
* Read a file and return it in a String
* @param fName
* @return
*/
private String readFile(String fName) {
String properties = null;
try {
System.out.println("---------- Opening the file");
//to actually retrieve the resource prefix the name of the file with a "/"
InputStream is = this.getClass().getResourceAsStream(fName);
//we now have an input stream. Create a reader and read out
//each character in the stream.
System.out.println("---------- Input stream");
InputStreamReader isr = new InputStreamReader(is);
char c;
System.out.println("---------- Append string now");
while ((c = (char)isr.read()) != -1) {
properties += c;
}
} catch (Exception e) {
}
return properties;
}
}
I call my class constructor like this:
Configuration config = new Configuration("/config.properties");
So in my class, "file" should have all the content of the config.properties file, and the fileName should have this value "/config.properties".
But the "name" is null because the file cannot be found... I know this is the path of the file which should be different, but I don't know what i can change... The class is in the package com.mycompany.blackberry.utils
Thank you!
