Subject Re: WAR format question
Date Tue, 04 Feb 2003 08:34:12 GMT
Read-only files can be placed anywhere you want.  For files that you need to
write to, use the 'javax.servlet.context.tmpdir' attribute of the
ServletContext (since you can't write to a WAR file :).  Assuming that your
servlet extends GenericServlet (this includes the cases of HttpServlet, and
Tomcat's default JSP page Servlet), then something like:

  String tmpDir =
  File outFile = new File(tmpDir, "myFile.ext");
  OutputStream outF = new FileOutputStream(outFile);
  // write something here
