| Session ID from ResourceSet.getResource(URI) [message #376723] |

I was wondering if anyone could tell me if it is possible to retrieve a
session ID after downloading an EMF generated XMI file from a web server.
My code looks like this:
ResourceSet set = new ResourceSetImpl();
URI uri = URI.createURI(http://www.myserver.com/MyXMIFile.suffix);
Resource res = set.getResource(uri, true);
MyModelElement el = (MyModelElement) resource.getContents().get(0);
This code retrieves the xmi file for me even if the file is stored on a
remote server. The problem is that the xmi file might be protected and the
user will be asked to log-in first. So far so good, but now the client side
needs to know the session id (jsessionid) that was created on the server
(for future requests). How can I retrieve this ID? Is it stored with the
Resource or the ResourceSet object. I can usually retrieve it from an
HttpURLConnection (which is probably used internally by EMF). Can I access
this object anywhere?
Any help appreciated,
--Dirk

Dirk,
All of the interaction with streams is funneled through the URIConverter. For
the case of a URI with http protocol, this method in URIConverterImpl is
eventually called to open a stream:
protected InputStream createURLInputStream(URI uri) throws IOException
{
URL url = new URL(uri.toString());
URLConnection urlConnection = url.openConnection();
return urlConnection.getInputStream();
}
It sounds like you may need a special resource set with a special URI converter
that takes your session ID into account.
