It might be your output stream.. here's my code, which does work:
File imagedata = new File(img.getImageLocation(),
img.getImageId() );
resp.setContentType( img.getImageType() );
RandomAccessFile raf = new RandomAccessFile( imagedata, "r" );
resp.setContentLength( (int) raf.length() );
ServletOutputStream out = resp.getOutputStream();
byte [] loader = new byte [ (int) raf.length() ];
while ( (raf.read( loader )) > 0 )
{
out.write( loader );
out.flush();
out.close();
}
