Java Forum / First Aid / September 2004confused about Java I/O, byte[] and streams
I have an array of bytes which contains binary data. How do I go about piping this data into a servlet output stream? PrintWriter out = response.getWriter(); out.print(mybytes); //mybytes has type byte[]. This doesn't seem to work thanks Luca > I have an array of bytes which contains binary data. > How do I go about piping this data into a servlet output stream? > > PrintWriter out = response.getWriter(); > out.print(mybytes); //mybytes has type byte[].

For the archive, since I have a mix of strings and binary data, I used this trick to turn my strings into bytes: ServletOutputStream out = response.getOutputStream(); out.write("Content-Type: multipart/mixed;boundary=foo\n".getBytes()); out.write("\n".getBytes()); out.write("--foo\n".getBytes()); out.write("Content-Type: text/html\n".getBytes()); out.write(somestring.getBytes()); out.write("\n".getBytes()); Luca > I have an array of bytes which contains binary data. > How do I go about piping this data into a servlet output stream? > > PrintWriter out = response.getWriter(); > out.print(mybytes); //mybytes has type byte[]. This doesn't seem to work What exactly goes wrong? Sorry, but these two lines of Code don't give many hints as to what the actual problem is. I don't see any output when I do a view source.... I know it's binary, but still.... thanks Luca >> I have an array of bytes which contains binary data. >> How do I go about piping this data into a servlet output stream?

Sorry, but these two lines of Code don't give >> many hints as to what the actual problem is. As William said, you should use an OutputStream for binary data, since this is what writes raw bytes. Other then that, have you tried breaking down the problem into smaller units? Can you write that binary data into some file? If that works, look at what is different for your Problem then that, and so on. See you Stefan Free MagazinesGet these publications absolutely FREE for up to 12 months.
