To: Miguel Feitas (Package gov.nist.javax.sip.header.ims )

Hi.

I have a problem with the interfaces of package
gov.nist.javax.sip.header.ims, I can't get the headers of this package.

My code is:

public void processRegister(Request request, ServerTransaction
serverTransaction, SipProvider sipProvider){
try{
ToHeader to = (ToHeader)request.getHeader("To");
String publicIdentity = to.getAddress().toString();
VisitedNetworkIDHeader visited = (VisitedNetworkIDHeader)
request.getHeader("P-Visited-Network-ID");
String visitedNetworkIdentifier = visited.getVisitedNetworkID();

... and more
}

And launch this exception:

java.lang.ClassCastException: gov.nist.javax.sip.header.ExtensionHeaderImpl
at control.I_CSCF.processRegister(I_CSCF.java:94)
at control.I_CSCF.processRequest(I_CSCF.java:83)
at control.CSCF.processRequest(CSCF.java:396)
at gov.nist.javax.sip.EventScanner.deliverEvent
(EventScanner.java:185)
at gov.nist.javax.sip.EventScanner.run(EventScanner.java:426)
at java.lang.Thread.run(Unknown Source)

Can you help me?

Thanks
