Best way to write Export files

[Alvin Kutttikkat Antony <aa...@gw.ifkw.uni-muenchen.de>]

Hi there,
             I have to write export files to an another server.The code I am  using is not seams to be working fine .Some times it rewrites on an existing file.I am giving my code sample here

                     access = ACCESS_WRITE;
                    long time = System.currentTimeMillis();
                    long timeSpawned = time;
                    // this routine tries 30 seconds
                    // to open a file, if not successful
                    while(!isOpen && (((timeSpawned-time)/1000)<30))
                    {
                        timeSpawned = System.currentTimeMillis();
                        try
                        {
                            out = new BufferedWriter(new FileWriter(filename,true));
                            isOpen = true;
                        }
                        catch(IOException e)
                        {

                        }
                    }
                }
                if(isOpen)
                {
                    String line = "";
                    for(int i=0; i<attributes.length; i++)
                    {
                        String att = person.getAttribute(attributes[i]);
                        if(att==null && attributes[i].equals(PersonKeys.DATATYPE))
                            att = "cha";

                        if(att==null)
                            att = "";
                        line += att + delimiter;
                    }
                    out.write(line);
                    out.newLine();
                    out.flush();
                }
          Is there is an another better  way to do this?
          appreciating your replay
