Greetings all,
I am currently doing some readup on the JSR 180 SIP API
implementation. It clearly defines and describes all about
"javax.microedition.sip" package containing interfaces and
classes implementing SIP functionality.
In the GCF (Generic Connection Framework) to establish
connectivity with remote machine I use the foll.
StreamConnection sc = (StreamConnection) Connector.open("socket://127.0.0.1:9000");
But as per the JSR 180 developers importing javax.microedition.sip
will have to use the Connector.open() method but typecast it of
type SipClientConnection interface as follows:
SipClientConnection scc = (SipClientConnection) Connector.open("sip:alice@company.com:5060");
When I tried this out using J2ME Wireless Toolkit 1.0.4_01 it
compiled fine but I got ClassCastException during runtime which is
quite logical because javax.microedition.io does not know
interface SipClientConnection like it does StreamConnection.
Now I am stuck here wondering what to do?
Any suggesstions, advices, insights would be of great help!
Thanx,
adios & cheers!
LearningCurve.

The Sun WTK (v1 or v2) does not implement the SIP API. I do not know any real device that implements this API -- maybe some Motorola devices do though. Does anyone know?
