Hello and thanks for beeing so quick!
I think my problem might be related to what you say at the end,
"connectionHub shared??" I am gonna post a little bit of the code that I
have for the client:
.............................
ConnectionHub connectionHub = ConnectionHub.getInstance();
// A connection object represents a socket attached to an HL7
server
Connection connection = connectionHub.attach(SERVER, PORT,
new PipeParser(), MinLowerLayerProtocol.class);
// The initiator is used to transmit unsolicited messages
Initiator initiator = connection.getInitiator();
System.setProperty("ca.uhn.hl7v2.app.initiator.timeout",
Integer.toString(timeout));
.................................................................
But the server doesn't have any reference made to "connectionHub", should
it? this is the main code for the server:
.........................................
SimpleServer server = new SimpleServer(PORT, llp, parser);
Application handler = new ExampleReceiverApplication();
server.registerApplication("ADT", "A01", handler);
server.start();
.........................................
Thanks again!
