Error sending SIP request using NIST JAIN SIP API

I'm trying to send a REGISTER SIP request using NIST's implementation of the JAIN SIP API.

First I give the declarations of the data members of my SipController class:

private int port;
private long cseq = Math.abs(numberGenerator.nextInt());
private MessageFactory messageFactory;
private AddressFactory addressFactory;
private HeaderFactory headerFactory;
private SipStack sipStack;
private SipProvider sipProvider;

And here is the code that sends the request:

public void register(String aor,String serverAddress) throws ParseException,InvalidArgumentException,SipException  
    {  
        Address addressOfRecordObj = addressFactory.createAddress(aor);  
        ArrayList<ViaHeader> viaHeaders = new ArrayList<ViaHeader>(1);  
        try  
        {  
            viaHeaders.add(headerFactory.createViaHeader(InetAddress.getLocalHost().getHostAddress(),port,"udp",getNewBranch()));  
        }  
        catch (UnknownHostException e)  
        {  
            e.printStackTrace();  
        }  
        Request request = messageFactory.createRequest(  
                ....addressFactory.createURI(serverAddress),  
                ...."REGISTER",sipProvider.getNewCallId(),  
                ....headerFactory.createCSeqHeader(cseq++,"REGISTER"),  
                ....headerFactory.createFromHeader(addressOfRecordObj,Integer.toString(Math.abs(numberGenerator.nextInt()))),  
                ....headerFactory.createToHeader(addressOfRecordObj,null),  
                ....viaHeaders,  
                ....headerFactory.createMaxForwardsHeader(70));  
        request.addHeader(headerFactory.createContactHeader(addressFactory.createAddress("sip:127.0.0.1:"+port)));  
        log(">> "+request);  
        sipProvider.sendRequest(request);  
}

I call this method using the statement

sipController.register("sip:user@domain.com","sip:127.0.0.1:5061");

The value of the data member port is 5060.

What I'm trying to do is to send a request to another application running on my computer, which is listening on port 5061. This application is another instance of the same program that I'm sending the request from.

When I call the sendRequest() method of the SipProvider class, I get a javax.sip.SipException exception with message "IO Exception occured while Sending Request". This exception contains a java.net.BindException as its cause with message "Cannot assign requested address: Datagram send failed".

Here is the stack trace:

Any ideas on what I'm doing wrong?

For the record, I've solved this problem. It was a while ago so I don't remember exactly what was wrong but apparently I was using a wrong .jar file for the NIST implementation.
