Concurrency

843793Apr 23 2004 — edited May 19 2004
ok i have a Java RMI system that works, but is Java RMI concurrent?
In Socket Programming the server is set to listen for connections and
when a connection has been made it spawns a new thread to allow a new
connection to exist in a seperate thread but as far as the client is
concerned the thread is the server.

Can this be done in RMI or is RMI itself concrruent?


Thanks for the help


Rabi.

It doesn't itself, but since you can feed jaxb a DOM document from any source, you can always use a processor that does support xinclude and feed the result to the unmarshaller. Try this:

(1) Get the XInclude Engine at http://xincluder.sourceforge.net/

(2) build the xinclude document with something like:


DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware( true );
factory.setCoalescing( true );
DocumentBuilder parser = factory.newDocumentBuilder();
InputSource input = new InputSource();
input.setByteStream( new FileInputStream( fname ) );
Document masterDoc = parser.parse( input );
Document doc = DOMXIncluder.merge( masterDoc, input.getSystemId() );

(3) then unmarshal the document with:

JAXBContext jc = JAXBContext.newInstance( "my.context" );
Unmarshaller u = jc.createUnmarshaller();
MyClass x = (MyClass) u.unmarshal( doc );

there's probably a faster Sax equivalent of this. Also works (better) with Castor.

hope this helps,

Oops! sorry: looking at it again, I see I misread your question. I thought you meant using xinclude in a datafile (which I'd just worked out how to do) rather than in a schema (which I haven't worked out). Apologies.

Yes. JAXB 1.0 supports included and imported schemas.
Can you please attach the COS.xsd too
