https://www.experts-exchange.com/questions/21025678/JTAPI.html

Which exact implementation of JAPI will you be using?

Other from this: Actually google have quiote a lot hits as far as I remember :)

   Hi!

Have you looked at these sites (found them using Google :) )

Tomas,

The first site is also in my list and the second is the paper book the sources for which are in my first link :)

   Venabil,
I didn't see your post until after I posted mine.

Regards,
  Tomas Helgi

:) Yep - saw the timestamps. :) That's why I just mentioned it - haven't said you had copied them

I look at those but not working.

We are using phone CISCO
my computer has already been connected to my telephone.

My question is do i need to download the emulator DDL file from the CISCO for that phone type.

cos no matter what i try i still got the following message

net.xjtapi.XJtapiPeer could not be instantiated.

i has increase the points hopefully you experts can give me some hints
thankyou

   Hi!

Does this link help : http://forum.java.sun.com/thread.jspa?threadID=469061&start=0

Regards,
   Tomas Helgi

Not help at all.
That is what I have been trying

Do i need to download SIP provider DDL in order to create an instance using jtapi??

Most probably yes. I had not done anything with this for a while.

And you never answered my question - which implementation of jtapi are you using?

Sorry I dont quite understand the question 'which implementation of jtapi are you using"

Answer
Java

using java.sun.com example

I have checked my PC  Control Panel|Service and found one entry

Telephony - Provides telephony API (TAPI) support for progams that control telephony devices and IP based voice

My question is why i got the following error

net.xjtapi.XJtapiPeer could not be instantiated.

JTAPI is an API. You need an implementation. Which one are you using? From the class names it seems like you use:
http://sourceforge.net/projects/xtapi/

Can you confirm?

Yes. I 'm using sourceforge.net/projects/xtapi

I follow the info from the above link but i get the error net.xjtapi.XJtapiPeer could not be instantiated.

Do i need to install any JTAPI client software?

Depends. :)
First - had you seen this? - http://sourceforge.net/docman/display_doc.php?docid=10406&group_id=49686
 and had you followed it? Especially the part for the provider.

Can you also tellme which example from here: http://sourceforge.net/docman/?group_id=49686 you try?

I download the sample1. from the below link

http://sourceforge.net/project/showfiles.php?group_id=49686&package_id=43589&release_id=98523

and include jtapi-1.3.1.jar in the class path

I run again and got the following error

Can't get Provider: javax.telephony.JtapiPeerUnavailableException: JtapiPeer: net.xtapi.XJtapiPeer could not be instantiated.

I think i choose the MSTAPI provider as we are using WindowXMP

# Newer NT Based OS’s such as Windows 2000 and XP work fine.
# You must create the provider as such to invoke the MSTAPI provider:

    * myprovider = peer.getProvider(null);


My Incall program in which I have created a log file using Log4j
========================================
public class InCall {
 
  private static CreateLog4J sLog = new CreateLog4J();
  public static final void main(String args[]) {
        /*
     * Create a provider by first obtaining the default implementation of
     * JTAPI and then the default provider of that implementation.
     */
         try {
            sLog.LaunchLogFile();
        } catch (Exception e) {
            // TODO
        }
        Provider provider = null;
    try {
      JtapiPeer peer = JtapiPeerFactory.getJtapiPeer(null);
      //  JtapiPeer peer = JtapiPeerFactory.getJtapiPeer("net.xtapi.XJtapiPeer");
       
      provider = peer.getProvider(null);
    } catch (Exception excp) {
      System.out.println("Can't get Provider: " + excp.toString());
      System.exit(0);
    }

===========================================================


Now i get different errors like below

xception in thread main
java.lang.NoClassDefFoundError: org/apache/log4j/Logger
      at net.sourceforge.gjtapi.test.tapi3.Tapi3Logger.<clinit>(Tapi3Logger.java:37)
      at java.lang.Class.forName0(Native Method)

      at net.sourceforge.gjtapi.raw.ProviderFactory.initialize(ProviderFactory.java:305)
      at net.sourceforge.gjtapi.GenericJtapiPeer.getProvider(GenericJtapiPeer.java:189)
      at InCall.main(InCall.java:26)
Process exited with exit code 1.


====================================
I run the debugger, the error is caused by

provider = peer.getProvider(null);

Please advise. It seems to be getting better at least it net.xtapi.XJtapiPeer can be instantiated.

Do you have log4j jar in your class path? This is what it complains about. :)

The classpath does include log4j.jar

That's why i dont understand


-classpath C:\jdevstudio1013\jdev\mywork\JTelephoneAppl\JTelephoneAppl\classes;
D:\Jtapi-phone\jtapi-1.3.1.jar;D:\Jtapi-phone\log4j-1.2.11.jar;
D:\Jtapi-phone\Example\sourceForge\mstapi\mstapisp.jar;
D:\Jtapi-phone\Example\sourceForge\mstapi

I did  create a log4j.xml file which includes in the classpath as well

See below linke.

http://72.14.253.104/search?q=cache:f1qhNEn99lcJ:cvs.sourceforge.net/viewcvs.py/gjtapi/src/doc/Tapi3.pdf%3Frev%3D1.4+net.sourceforge.gjtapi.test.tapi3.Tapi3Logger&hl=en&gl=au&ct=clnk&cd=1&client=firefox-a

This is strange.

log4j.xml should contain basically only the log4j configuration.
How do you invoke your program?

It would be a reason but i dont know how to do it.

Have you worked on the tapi using SourceForge.net before?

I can't find the tapi3Provider.dll as the specification mentioned it before

There is nothing to install in order to use the Tapi3 provider. Just make sure that all jars
and needed props files (GenericResources.props, GenericCapabilities.props, Tapi3.props
etc.) are in your classpath and that Tapi3Provider.dll is in your java.library.path

I add the below, but i got the same error:

-Dlog4j.configuration=C:\log4j.properties


Exception in thread main
java.lang.NoClassDefFoundError: org.apache.log4j.Appender

log4j.properties

log4j.rootLogger=INFO, CON
log4j.appender.CON=org.apache.log4j.ConsoleAppender
log4j.appender.CON.layout=org.apache.log4j.PatterLayout
log4j.appender.CON.layout=ConversionPattern=%-5p -%m%n


***********************************************
***   I think the problem is

log4j is failing in trying to load
the org.apache.log4j.ConsoleAppender class from the same classloader,
sun.misc.Launcher$AppClassLoader@12f6684.  This classloader, of course,
cannot be a child of both of the Junit classloaders.

It fails in loading ConsoleAppender class

Exception breakpoint occurred at line 205 of URLClassLoader.java.

>>Have you worked on the tapi using SourceForge.net before?
Yeah - 3 years ago :)

The problem most likely is the version of the log4j or that it is simply missing ( or you have 2 of these)... :(So can you post the full line you start your programn with

As for the dll - I remember creating it. Here are some hints how: https://sourceforge.net/tracker/index.php?func=detail&aid=1578794&group_id=40963&atid=429338

Very thanks for the hints.

I've posted two questions re this. I will give all points to you. No matter this is solved or not.
I do appricate your help

Thought you can copy the dll file, Tapi3Provider.dll

I know nothing about visual studio. We are Oracle and java developer.

Do you mind send me the dll file?

Would you please give me some hints how to find the right version of the log4j
or check if i have 2 of these files...

. would you give me the step how to create a dll? The problem is I dont have visual studio

What version of the log4j are u using ??

>>Do you mind send me the dll file?
Unfortunatelly I do not have it. As I said somewhere - I worked on this quite a while ago.:(

With the JTApi? I do not really remember - I do not have it installed here..I have like 7 versions in my system

Wait a second. What does the method CreateLog4J does?

Venabili

This is the one to create a log file
i really hope i can solve this problem as i have already spent alot of effort and your help

i remote the create log bean
==
to Test i use sourceForget given code

you are right i think i have duplicate log4j i have removed the createJlog bean

not i got different error associated with Tapi3Provider
That's understandable as i dont have Tapi3Provider.dll

which sites i can find or how to i build one please help

I gave you an isntruction how to build it above, And I do not think it exists built somewhere :(

So just some few hints:
- Use the 2003 Windows Platform SDK, not the newer R2
- Use Visual Studio 6
- Include the platform sdk files as the very first in
visual studio. Sequence matters.


I do not understand the above instruction at all

Thanks Venabili.
Look like I wont be able to do it as I have no technical backgroud for building a DLL. ( No development tool as well)

Do you have any suggestion i can use such as SIP,etc?

It doesnt matter what methods we use. the most important i need to build a program to capture the incoming phone number.

Thanks

I'd say that I gave him the answers of the initial questions... but a delete is also ok

Thanks Venabill. even thought it doesn't really work cos i dont know how to create the DLL ..
but very thanks for giving me all the useful info.
I was sick for a few days so I can't update.
