Can't write file on server using Servlet

Question

Dear programers,
I have written a little method that creates a simple file. This method works fine when I execute it on my PC but it doesn't work when the servlet execute it.
For example:
public void test(){
FileOutputStream fileHTML = null;
String html_file_name = "\\\\MyServer\\dir\\filename.html";
try{
//create new HTML file
fileHTML = new FileOutputStream(html_file_name);
String text = "Hello World";
fileHTML.write(text.getBytes());
fileHTML.close();
}catch(IOException ex){
System.err.println(e.getMessage()+ " Cann't create new HTML file!");
I don't get any exception, it seems that the file is written to the server but it doesn't.
What can be the problem?

Answer 1

a) You do mean Servlet not Applet don't you? Applets aren't allowed access to the file system. If it's an applet open the "java console" window on the browser. You'll probably see a security exception.
b) If it's really a servlet any errors are likely to turn up on the server's log files. Check those. You file path doesn't contain a drive letter so maybe the drive letter is wrong in the servlet environment.
c) Always use Writers to output text, not Streams. That's not the source of your problem but it make for much messier code.
