This is really a simple Java issue.

When you say that it is not a file you are correct.  It is just a  
java.lang.btye[].  But on the other hand a java.io.File is not a file  
either.  It is just a pointer to the actual files in your  
filesystem.  If you want to write the byte[] out to a new file on  
your filesystem just use simple file io.

Something like ......

OutputStream out = new FileOutpuStream(new File(<file_name_goes_here>));

byte[] bytes = new byte[1024];
int bytesRead;

while ((bytesRead = in.read(bytes)) != -1) {
     out.write(bytes, 0, bytesRead);
