forward call in b2bua jain slee

[ichi]

Hi everyone, I'd like to modify a bit the b2bua example to forward all
incoming call to an address. I found this error:

which pointed out in the following line:

ClientTransaction ct =
sipProvider.getNewClientTransaction(invite);

Any hint where's the cause of Null in the outgoing request? I only
tried to change the ToHeader. Here's the code.

public void onINVITE(javax.sip.RequestEvent event,
ActivityContextInterface aci) {

request = event.getRequest();
tracer.info("Receiving INVITE");
aci.detach(sbbContext.getSbbLocalObject());

try {
final DialogActivity incomingDialog = (DialogActivity) sipProvider
.getNewDialog(event.getServerTransaction());
final ActivityContextInterface incomingDialogACI = sipAciFac
.getActivityContextInterface(incomingDialog);

//Create a request
String toSipAddress = "open-ims.test";
String toUser = "bob";
String toDisplayName = "Bob";
SipURI toAddress = addressFac.createSipURI(toUser, toSipAddress);
javax.sip.address.Address toNameAddress =
addressFac.createAddress(toAddress);
ToHeader toHeader = headerFac.createToHeader(toNameAddress, null);
FromHeader fromHeader = (FromHeader)
request.getHeader(FromHeader.NAME);
MaxForwardsHeader maxForwards = (MaxForwardsHeader)
request.getHeader(MaxForwardsHeader.NAME);
ContentTypeHeader originalContent = (ContentTypeHeader)
request.getHeader(ContentTypeHeader.NAME);
ContentTypeHeader contentTypeHeader =
headerFac.createContentTypeHeader(originalContent.getContentType(),
originalContent.getContentSubType());
ListIterator<ViaHeader> iter = request.getHeaders(ViaHeader.NAME);

ArrayList viaHeaders = new ArrayList();
while(iter.hasNext()){
ViaHeader viaHeader = iter.next();
ViaHeader viaHeaderr =
headerFac.createViaHeader(viaHeader.getHost(), viaHeader.getPort(),
viaHeader.getProtocol(), "null");
viaHeaders.add(viaHeaderr);
}

CallIdHeader callId = sipProvider.getNewCallId();
SipURI requestURI = (SipURI) request.getRequestURI();
ContactHeader contact =
(ContactHeader)request.getHeader(ContactHeader.NAME);
long cseq = 1;
CSeqHeader cSeq = headerFac.createCSeqHeader(cseq, request.INVITE);
String sdp = null;
if(event.getRequest().getContent()!=null){
sdp = new String(event.getRequest().getRawContent());
}

//Send the Request INVITE
Request invite =
messageFac.createRequest(contact.getAddress().getURI(),
request.INVITE, callId, cSeq, fromHeader, toHeader, viaHeaders,
maxForwards, contentTypeHeader, sdp);
invite.addHeader(contact);
ClientTransaction ct = sipProvider.getNewClientTransaction(invite);
final DialogActivity outgoingDialog = (DialogActivity)
sipProvider.getNewDialog(ct);

//Attach outgoing dialog
final ActivityContextInterface outgoingDialogACI = sipAciFac
.getActivityContextInterface(outgoingDialog);

final SbbLocalObject sbbLocalObject = sbbContext
.getSbbLocalObject();
incomingDialogACI.attach(sbbLocalObject);
outgoingDialogACI.attach(sbbLocalObject);

setIncomingDialog(incomingDialogACI);
setOutgoingDialog(outgoingDialogACI);

tracer.info("Sending Second Leg");
outgoingDialog.sendRequest(ct);

} catch (Throwable e) {
tracer.severe("Failed to process incoming INVITE.", e);
replyToRequestEvent(event, Response.SERVICE_UNAVAILABLE);
}
}

The NPE occurs inside JAIN SIP RI, which should mean an issue with the
request content, probably related to using headers from one request in
another, try to .clone() each header you want to copy instead.

Anyway, the code does not seems to be best solution, when using
dialogs you should first create the dialog, using
sipProvider.getNewDialog(from,to) or
sipProvider.getNewDialog(incomingDialog,boolean), then copy request
using DialogActivity.createRequest(incomingRequest), extend it if
needed, and finally use the dialog to send the request
DialogActivity.sendRequest(outgoingRequest);
