}以上代码一直运行不了,我已经添加了,comm.jar,win32com.dll,xtapi.jar 等包,可是运行总是提示不对.
请问xtapi.inf如何修改modem信息,我的modem是enet 800,还有需要配置什么才可以运行?jb2006 错误提示:C:\Borland\JBuilder2006\jdk1.5\bin\javaw -classpath "D:\JTAPI\cti\1\classes;C:\Program Files\Java\jdk1.6.0_04\lib\jtapi1.3.1.jar;C:\Program Files\Java\jdk1.6.0_04\lib\xtapi.jar;C:\Program Files\Java\jdk1.6.0_04\lib\mstapisp.jar;C:\Program Files\Java\jdk1.6.0_04\lib\gjtapi-1.7.jar;C:\Program Files\Java\jdk1.6.0_04\lib\comm.jar;C:\Borland\JBuilder2006\jdk1.5\lib\jconsole.jar;C:\Borland\JBuilder2006\jdk1.5\lib\tools.jar;C:\Borland\JBuilder2006\jdk1.5\lib\htmlconverter.jar;C:\Borland\JBuilder2006\jdk1.5\lib\dt.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\jsse.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\im\indicim.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\im\thaiim.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\jce.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\deploy.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\javaws.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\charsets.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\rt.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\ext\dnsns.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\ext\sunpkcs11.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\ext\localedata.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\ext\sunjce_provider.jar;C:\Borland\JBuilder2006\jdk1.5\jre\lib\plugin.jar"  org.Outcall

Answer 1

如果谁有简单的可以运行的代码[jtapi应用]发给我一个好吗?(将需要的包一同给我更好了.)[email protected]十分感谢.

Answer 2

另外ProvidersEmulator
Voice Modem
SIP
Inverter
RMI
XTAPI都是什么意思,应用于什么环境? 

Answer 3

你上面定义的那些类我查了下JDK1.5文档都没有这些类!

Answer 4

我有这个代码，或者你自己去下载也可以
我告诉你网址：
http://java.sun.com/products/jtapi/   这个是java官网的，而我工作的时候Cisco的JTAPIhttp://www.cisco.com/en/US/docs/voice_ip_comm/cucm/jtapi_dev/3_1/JTAP_con.html
