i have a BufferedImage that I am writing into a JPEG file. I don't get
any errors, but the file doesn't seem to be created.

i'm doing this:
              try {
                      if (img == null) System.out.println("failed!!");
                      File file = File.createTempFile("rubbish","jpg");
                      ImageIO.write(img, "jpg", file);
              } catch(IOException e) {
                      System.out.println("failed:(");
              }
but I check in the local directory where I am running the program and
nothing gets created

Perhaps you should read the documentation for File.createTempFile(). It's always
a good idea to read docs. to find out what a method does, before using it and
getting surprised because it doesn't do what you *assumed* it would. Look in
the correct directory and you might find your missing file.
