@gvag
thank you for your response! i didn’t know which dependency are really necesseary… but
i found out which *.jar and dll were needed. If someone else need this informations,
in class path:
- Tapi3.gtapi ->configuration-file
- log4j.props ->configuration-file
- GenericResources.props ->configuration-file

in lib path:
- gjtapi-1.9-rc1.jar
- gjtapi-tapi3-1.9-rc1.jar
- jtapi-1.3.1.jar
- log4j-1.2.12.jar

somewhere referenced – for ex C:\windows\system32\
- Tapi3Provider.dll

of course you need your telefon-driver installed.

First make sure your PBX supports JTapi services (if your PBX supports TAPI doesn’t meen that can support JTapi), second make sure that the jtapi.jar library you have in hand supports the JTapi services you have. Third please provide the source code that causes the error. From the error you provided seems that you are trying to do something similar to “JtapiPeer peer = JtapiPeerFactory.getJtapiPeer(“”);” – that is passing no argument. Some time, a vendor specific implementation of JTapi requires you to ask for the JTapiPeer passing a specific argument. For example, for Avaya JTapi services, you need the following :
JTapiPeer jtapiPeer = JtapiPeerFactory.getJtapiPeer(“com.avaya.jtapi.tsapi.TsapiPeer”).

hi hb, ich komme aus Vietnam aber arbeite und studiere in Deutschland. Zur Zeit muss ich auch für CiscoJTAPI programmieren. Viel Spaß mit JTAPI

@pink
Danke Pink, ich nehme an dass du auch aus Deutschland kommst! Ich werde es damit mal versuchen und lasse es Dich wissen ob es funktioniert hat! Die Diplomarbeit ist super ich werde mir Sie mal durchlesen! Vielen Dank!

Englisch:
Thanks Pink, I assume that you also come from Germany! I will therefore
try it and let you know whether it worked! The thesis
is perfect, I will read it! Thank you very much!

@gvag
Thank you, that this site exists! It really helps me on!

http://blog.nominet.org.uk/tech/2008/01/25/experiments-with-jtapi-part-1-making-a-call/ is a example for your solution. i take all classes of gvag and take extra code:
Address srcAddr = provider.getAddress(src);
srcAddr.addCallObserver(new CallObserver() {
public void callChangedEvent (CallEv [] eventList) {

}
});

it work fine.

About the JTAPI case study i have an interesting document for you but it speak on german: Jtapi thomanek,jan (search with goole)

No, i don’t find the solution, it doesn’t work!

the code i posted does not work
and i can’t find the mistake!

The Method addressChangedEvent is not called when a call comes in.
I just want that when someone calls my number, this indicates, for
Example in the Console.

Good to know that you found out the solution. Would you be interesting to write a short description of the project you are working on? short of a JTapi case study.

Sorry,
the PhoneObserver implements AddressObserver!

many thanks for your help!

hey gvag,

it doesen’t work

I have these two classes:

## PhoneObserver.java ##
[...]
@Override
public void addressChangedEvent(AddrEv[] eventList) {
System.out.println(“CALL”);
}
[...]

## Phone.java: ##
[...]
peer = JtapiPeerFactory.getJtapiPeer(“net.sourceforge.gjtapi.GenericJtapiPeer”);
prov = peer.getProvider(providerName);

obsListener = new PhoneObserver();

address = prov.getAddress(listeningAddr);
address.addObserver(obsListener);
[...]
