Where do you put the javax pacakages?

I like to know where do you put the javax packages. such as telephony. I try
to compile and I always get the error that it can not find the packages. As
for example;

import javax.telephony.*;
import javax.telephony.events.*;
import javax.telephony.callcontrol.*;
import javax.telephony.callcontrol.events.*;
/*
* The MyCallCtlOutCallObserver class implements the CallControlCallObserver
* interface and receives all events associated with the Call.
*/

I tried placing it in the jre in the lib ext and nothing works.

Thank you in advance.
