Does anyone know how to make a java application flash in the taskbar without taking the focus. I want to have a java app flash in the taskbar when a certain event happens. I found an existing windows dll that will do the trick. I found info on using JNI but haven't found anything on using an existing windows dll. Hopefully there is a way without using JNI.

create another class that extends Thread and let that class do the work of loading the picture. The new thread does the work of loading your picture while the rest of the application keeps working on it own thread.

I need to write a file to a remote server, but I can not use RMI, or client server sockets. Any suggestions on how I would do that.

I am trying to run the outcall.java example and I keep getting the below error

javax.telephony.InvalidArgumentException
java.lang.NullPointerException
MyOutCallObserver.callChangedEvent
java.lang.NullPointerException

I have all the correct jar files and other files in my classpath. It complies with no problem but I just keep getting the above error. Below is the code.

import javax.telephony.*;
import javax.telephony.events.*;
//import MyOutCallObserver;


/*
* Places a telephone call from 476111 to 5551212
*/
public class Outcall {

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.
*/
Provider myprovider = null;
try {
//JtapiPeer peer = JtapiPeerFactory.getJtapiPeer(null);
JtapiPeer peer = JtapiPeerFactory.getJtapiPeer("net.xtapi.XJtapiPeer");
//myprovider = peer.getProvider(null);
myprovider = peer.getProvider(null);
System.out.println("got provider");
} catch (Exception excp) {
System.out.println("Can't get Provider: " + excp.toString());
System.exit(0);
}

/*
* We need to get the appropriate objects associated with the
* originating side of the telephone call. We ask the Address for a list
* of Terminals on it and arbitrarily choose one.
*/

Address origaddr = null;
Terminal origterm = null;
try {

origaddr = myprovider.getAddress("0");
//Just get some Terminal on this Address
Terminal[] terminals = origaddr.getTerminals();

if (terminals == null) {
System.out.println("No Terminals on Address.");
System.exit(0);
}
origterm = terminals[0];

} catch (Exception excp) {
// Handle exceptions;
System.err.println( excp) ;
}

// Create the telephone call object and add an observer.
Call mycall = null;
try {
mycall = myprovider.createCall();
mycall.addObserver(new MyOutCallObserver());
} catch (Exception excp) {
// Handle exceptions
System.err.println(excp) ;
}

/*
* Place the telephone call.
*/

try {
Connection c[] = mycall.connect(origterm, origaddr, "6788939416");
} catch (Exception excp) {
System.out.println(excp.toString());
}

}

}
I wasn't sure which forum this went in so I posted it here. I have searched the web for about 2 days and there is very little information regarding xtapi errors. I have found several regarding the classpath issues which I corrected but not much else. Any help at all would be apprectiated

I meant the folder on my desktop is called java_telephony not java_api.
I run the command java Outcall from the simple directory

I have a folder on my desktop java_api. In that folder I have a folder that holds the jar files
comm.jar, xtapi.jar and mstapisp.jar. I then have another folder in the java_api folder called
simple that has the outcall and myoutcallobserver java and class files
