无法写入Java中的远程文件系统

Question

I'm using Play! framework. I want to access remote file (read & write) connected through LAN. While accessing to read a file for a first time in java. I was unable to read the file. If i load the URL in browser once (successfully) then i am able to read the file in java too. ( I am reading using HttpURLConnection) Now i want to write into the file which i can't. There are no errors or exceptions. But the content is not written to the file. I have given 777 permission to my Play! application. What could be the issue. How can i solve it.

EDIT:

To update the file i have written this code

public void createFileInPath(String filePath, Object contents)
   {
        try{

        Writer output = null;
        String text = contents.toString();
        File file = new File(filePath);
        output = new BufferedWriter(new FileWriter(file));
        output.write(text);
        output.close();

        }catch (Exception e){
        System.err.println("Error While Creating File in FileManager.java: " + e);
        }
   }

Try using java.io.* classes. You dont have to treat it specially if it is already mounted on your system (linux) or mapped(windows).

All you need to do is pass the right path and operate as if it is a local file.

To read a file:

    BufferedReader in = new BufferedReader(new FileReader("my file path"));
    String line = null;
    while ((line = in.readLine()) != null) {
        System.out.println(line);
    }
    in.close();
    // To write into a file
    PrintWriter out = new PrintWriter(new FileWriter("my file path"));
    out.println("some content");
    out.flush(); // required to flush the content to filesystem
    out.close();
