Hi Bjorn, This should indeed work out of the box. Which HTTP connectors are you using? If using the internal/default ones, try adding Jetty/Simple extensions/Apache HTTP client to see if it helps.

It seems like I need to use org.restlet.representation.OutputRepresentation. From what I've read online and in the book, I expect this to work, however inefficiently, "out of the box", but I did this: this.getRangeService().setEnabled(true); in my top-level restlet, just to be sure. Unfortunately, I've found the server hangs after serving the required amount of data. I have experimented with just supplying the amount of data actually requested, but that causes problems as well. My code looks something like this the code below. Any help appreciated, as I'm a bit baffled and not really sure how to proceed. So far most of my data has been automagically converted to XML without much thought, and I'm not really sure how this part of the process actually works. List<Range> ranges = getRequest().getRanges(); Range ranget; if( ranges.size() == 0 ) ranget = null; else if( ranges.size() == 1 ) ranget = ranges.get(0); else return // error not supported!!! final Range range = ranget; if( range != null && range.getSize() + range.getIndex() > ms.getTotalSize() ) return // error: requested out of range //Note: I'm not actually using the range found above, but I've been playing with it, so I thought I'd include it. OutputRepresentation os = new OutputRepresentation( new MediaType(m.getMimeType()), ms.getTotalSize()) { @Override public void write(OutputStream outputStream) throws IOException { Iterator<MediaChunk> curChunk = ms.getChunks().iterator(); byte[] b = new byte[10240]; long cur = 0; long amt = 0; try { while( curChunk.hasNext() ) { MediaChunk mc = curChunk.next(); InputStream is = mc.openStream(); try { while( true ) { int r; r=is.read(b); if( r == -1 ) break; cur += r; amt += r; outputStream.write(b, 0, r); //HANGS HERE! } } finally { is.close(); } } } finally { outputStream.close(); long s = ms.getTotalSize() ; if( amt != s ) throw new IOException( "Error reading requested data: " + amt + " : " + s ); } } } ----------------------------- Bjorn Roche http://www.xonami.com Audio Collaboration http://blog.bjornroche.com ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=29466 26 ------------------------------------------------------ http://restlet.tigris.org/ds/viewMessage.do?dsForumId=4447&dsMessageId=2949452
