View Full Version : I require a File object without writting to a file

My Betters,

I have a java program that currently takes a BufferedImage and write it to a jpg file. Then I upload the file to a server. The method I use to upload things take a File object.

But I wanna send the Buffered Image directly to the server without writing it into an actual file. (Security concerns on the client side) Anyone know where I can find out how?

Is it possible to write the File to the RAM somehow?

Can you show some of your code dealing with the image?

Luckily for me I actually found a method that deals with streams instead of files. After I read that file objects in java contain no more information then the path to the file, I gave up trying to store information into the file object.

This is my current code right now. It works :D

ClientHttpRequest is a class someone else wrote that mimic HTML form input using java. I have another question tho, since ClientHttpRequest is in sourcecode form, I just appended it after the class I'm writing, which made it long and ugly. Is there a way I can compile it separately and "import" it somehow?

ByteArrayOutputStream outstream = new ByteArrayOutputStream();

ImageIO.write(image_out, "jpg", outstream);
//System.out.println(output + Filename);
//mimic form data

ClientHttpRequest request = new ClientHttpRequest(output+Filename);
request.setParameter("Filedata", "Screenshot.jpg", new ByteArrayInputStream(outstream.toByteArray()));
