[jgap-users] Reading configuration from file !!

[Jarek L. <jl...@st...>]

Hi,
I have been recently writing a small application using JGAP. It has GUI 
using SWING and I've encountered a problem with writing and reading my 
configuration to/from a file. I want to write to a file configuration 
attributes such as population size, natural selectors etc. from a GUI, 
and later read them into GUI from a file again. The problem is when I 
write configuration to file and try to read them into GUI something goes 
wrong!! Below I enclose my functions for writing and reading 
configuration to/from a file. Could someone help me out by explaining 
where I'd made a mistake or show an example showing how to use 
configuration for managing files (reading or writing). I use JGAP in 
version 3.3.3.

public void WriteConfigToFile() {
        int returnVal = fc.showSaveDialog(null);
       
        if(returnVal == JFileChooser.APPROVE_OPTION) {
            String filename = fc.getSelectedFile().getPath();
            try {
                FileOutputStream fos = new FileOutputStream(filename);
                ObjectOutputStream out = new ObjectOutputStream(fos);
                out.writeObject(conf);
                //out.writeUTF(conf.toString());
                out.flush();
                out.close();
            } catch(IOException e) {
                System.err.println(e);     }}}

public void ReadConfigFromFile() {
        int returnVal = fc.showOpenDialog(null);
       
        if(returnVal == JFileChooser.APPROVE_OPTION) {
            String filename = fc.getSelectedFile().getPath();
           
            try {
                FileInputStream fis = new FileInputStream(filename);
                ObjectInputStream in = new ObjectInputStream(fis);
                conf = (Configuration)in.readObject();
                //conf = new Configuration(filename, false);
            } catch(Exception e) {
                System.err.println(e);   }
