I want to write the data retrieved from the user to a txt file.
That's sounds easy right but I have been trying this for the past 4 hours , infact I cant even write anythign to a file thru the servlet please help ...
It works fine in a main method of a decent class when I run it but it just doesnt write to the file when I run the servlet...
here is the doGet() method :
public void doGet(HttpServletRequest request,
throws IOException, ServletException
PrintWriter out = response.getWriter();
BufferedWriter pw = new BufferedWriter(new FileWriter("memberfile.txt", true));
System.out.println("Why isn't it working?");
System.out.println("IOException thrown in writeMember() method");
Why isn't it writing to the file? is there anything I dont know? ... please help and thanks

I as just looking for it in the wrong place, the file actually is being saved in the bin folder ,,, oh I learned somethign new today.... snap I am one slow and dumb person....
BTW, I always recommend using the Unix form of filenames in Java. Java handles them in an OS-independent way, and you won't get zapped when the compiler turns "YourRootDir\memberfile.txt" into "YourRootDirmemberfile.txt" because the backslash is an ESCAPE character!
- Relative to the web-app root. The call getServletContext().getRealPath(relativePath) will return the absolute path for a resource - for instance, getServletContext().getRealPath("WEB-INF/web.xml") will give you the location of the "web.xml" file. The problem with this approach is, some application servers run the entire web-app from a war or a database, not from the filesystem, and will actually return null. If you just need need read-only access, use getServletContext().getResource(relativePath) or getServletContext().getResourceAsStream(relativePath).
- In a location given by a configurable parameter. The most natural means of configuration is a servlet or application parameter specified in the web.xml file; you can retrieve them using getServletConfig().getInitParameter(name) and getServletContext().getInitParameter(name) respectively. Arguably, access relative to the user's home directory (System.getProperty("user.home")) should be included in the list; I'm not fond of it because it opens the possiblity of conflicts between web-applications.
