Loading Properties file

[morteza av]

I write tow method for my class to obtain correct file path in FileInputStream class to loading Properties file:

    public String getClassName() {
        String thisClassName;
        //Build a string with executing class's name
        thisClassName = this.getClass().getName();
        thisClassName = thisClassName.substring(thisClassName.lastIndexOf(".") + 1, thisClassName.length());
        thisClassName += ".class";  //this is the name of the bytecode file that is executing
        return thisClassName;
    }

    public String getLocalDirName() {
        String localDirName;
        //Use that name to get a URL to the directory we are executing in
        java.net.URL myURL = this.getClass().getResource(getClassName());  //Open a URL to the our .class file
        //Clean up the URL and make a String with absolute path name
        localDirName = myURL.getPath();  //Strip path to URL object out
        localDirName = myURL.getPath().replaceAll("%20", " ");  //change %20 chars to spaces
        //Get the current execution directory
        localDirName = localDirName.substring(0, localDirName.lastIndexOf("/"));  //clean off the file name
        return localDirName;
    }

and use:

        try {
             Properties properties = new Properties();
             properties.load(new FileInputStream(getLocalDirName() + "/setting.properties"));
            String firstnm = properties.getProperty("Fname");
            jTextField1.setText(firstnm);
        } catch (IOException ex) {
            System.out.println("Could not open Config file");
        }

Its work in netbeans IDE correctly, but when I compile my class the .properties file miss in dist folder. It don’t work even I paste .properties file inside my app folder.
Can you help me?

Where does setting.properties file exist ?

inside some package(of class directory) ?

[Wouter Oet]

Small hint for the method getClassName(): look at the method Class.getSimpleName()

setting.properties exist in class directory.

I believe you don't need to do all the stuff you are doing.

Just use as shown

try {  
            Properties properties = new Properties();  
            properties.load(YourClassName.class.getResourceAsStream("/setting.properties"));  //Assuming it is at top level, not under any package
            String firstnm = properties.getProperty("Fname");  
            jTextField1.setText(firstnm);  
        } catch (IOException ex) {  
            System.out.println("Could not open Config file");  
        }  

Remember the argument to getResourceAsStream(), should include the packages path if the properties file is under any java package.

For ex, if it is under com/xyz/setting.properties, then the argument should be "/com/xyz/setting.properties".
