Thank you for the link (although it's in php). That root <b>entry</b> I got from some C# example. I'm trying to implement a form of ReSTful webservice, where I call a URI (discovery will be through ROME, I suspect) and parse the xml with jdom (at least it does that well ;). In order to change the text values of the elements, I will have to iterate through them (jdom). Then I put them back together in a document and PUT them back on the server. That was the theory :(<br>
<br>You are right in noticing the empty first element - that slipped past my eye. Although I did get this damnable code PUTting to the server with a document parsed from a file (the file being the result of a jdom document output). That there made me think the jdom api was fishy ;) I'll try ROME and report back.<br>

I may be wrong here, but it seems that JDom is perhaps not the choice to use when posting to an atom feed. I say this because I can output a document to a file with no problems. However, I can't out the document to an http stream. I've wrapped the stream in a buffer and called flush on it to no avail. I know that there isn't a problem with the stream, because when I create a new document from the file where I output to originally, it works. But I don't want to have to write to a file (or even a string). I want to find a solution that works. My solution is fine until I want to post the results back to the server :(. Perhaps ROME is the way to go?</div>

Thank you for the inputs. However, I have to disagree. My problem can be distilled like so:<br>
<br>
If I create a document from an ArrayList<Element> and try to post, the server doesn't update.<br>
If I create a document by parsing the file made from a document that
was made from ArrayList<Element> and post, the server updates.<br>
<br>
This makes me think that the http output stream is not at fault, since
it works for the case for the document built from a parsed file. (I
have also since wrapped the httpOutputStream in a bufferedStreamReader
and called flush(). Still nothing). It makes me think that there is a
setting which is read from the parsed file which is not read from the
ArrayList<Element>.<br>
<br>
So the above makes me wonder if ArrayList<Element> is a suitable list to work with. What other container could I use?<br>
<br>

I agree with Jason that you should close the output stream (which will also flush) before getting the response code.<br><br>Also, if you're going to be doing a lot of http processing I recommend using Apache's httpclient instead of dealing with Java's HttpConnection directly.<div>
