In my code I receive uploaded image file and want to save it in two different sizes.

I am saving it using the given code:

The files of size 0 bytes get saved with the given names.
when I save only one at a time then it gets saved properly.
Please help me to debug the problem.

Step 1 exhausts the input stream, so there's nothing in step 2 to read any more. You could read the entire contents of the input stream into memory using a ByteArrayOutputStream, and then work with the resulting byte[] as many times as you need to.

Or write to both files simultaneously:
Be sure to notice my remark on line 20.

I tried the below code:

Now only one file is getting saved but the the another file is just created with size 0 byte.

You'll still need to flush() and close() the output streams.

Thank you Rob,

I followed your instructions and tried but again the same results. File with both names created but with size 0 byte.

How have you made sure that the input stream does contain any data?

In my second message after the last line baos.writeTo(out); I flushed both the out and out2 and again tried. This time the same results.

I followed your instructions and write the code (please see my second message with code), I was able to save one file correctly.

When I try to save only one file it gets saved. It means I am getting the input stream.

I tried the below code to find inputstream has some data!



Then one by one I tried to run codes suggested by both of you. Ulf your doubt is correct, the loop runs not for a single time.
