[jdom-interest] Help XSLT/Piped Streams?

Yusuf, Nick, many apologies for the long delay in following up on this.  I
hope no offense is taken.

Yusuf, from your example, it looks like the issue is with something with
piped input streams.

Yes, that's what it looks like to me also.  From Yusuf's example, if I add
a close() to the output pipe, it seems to work.  I think Xerces (or
whatever parser you are using) is reading from the input stream, and it
hangs waiting for the output stream.

    PipedInputStream pi = new PipedInputStream();
    PipedOutputStream po = new PipedOutputStream();
    //    pi.connect(po);
    // po.flush();

    //transformer.transform(new InputSource("foo.xml"), new Result(new
    System.err.println("Calling Transform");
    transformer.transform(new StreamSource(pi), new StreamResult(new
    System.err.println("Done with Transform");

(Using the current TrAX APIs).  If I don't do the close(), and just do the
flush instead, it just hangs inside the transform, which I think replicates
your problem.  So, I don't think this has anything to do with Xalan, it has
to do with piping streams and possibly differing behavior with various
versions of the JDK in regards to PipedInputStream.

BTW, you might be better off using the JDOM DOM adapter instead of piping

Scott, Did you get any info from my test case. Do you need me to provide
you with more info etc
