I like it.. But I wonder if we can do something to handle streams out of band in general. Here's a use case I'm thinking about...
A big file is being posted to a servlet and the servlet wants to pass that input stream it's receiving to a JMS consumer somewhere in the back end. So there is no actual file or URL to identify that stream but I want to 'pass' the stream to a consumer using JMS routing/load balancing. And ideally the contents of the stream would be sent out band with respect to the JMS network. It seems to me that if we can handle a case like that, transmitting URL or File based resources is just a simple case of the above.

Saw an interesting blog post today... http://weblogs.java.net/blog/guruwons/archive/2006/11/sending_large_f.html As I mentioned on the comments, I'd like to extend this a little to support both out-of-band transfer (e.g. its basically a message with a URL in it to that the user can download the file from some remote destination) or the file is actually sent over the JMS network, so it can act as a facade to the existing JMS Streams feature... http://incubator.apache.org/activemq/jms-streams.html So am thinking from a client API perspective they do one of the following... // send a message out of band... FileMessage message = session.createRemoteFileMessage(new URL("http:///foo.com/bar.jpg";)); // send a local file over the JMS network FileMessage message = session.createLocalFileMessage(new File("~/myfiles/bar.jpg")); then for consumers... if (message instanceof FileMessage) { FileMessage fileMessage = (FileMessage) message; InputStream in = fileMessage.getInputStream(); // lets read the file... // or lets force the file to be manifested as a local file so we can work directly on the file instead URL url = fileMessage.getURL(); // we can now open the file as many times as we like... } Thoughts? -- James ------- http://radio.weblogs.com/0112098/
