xdotool, XSendEvent or something like them

Hi

I've got a java program that takes many hrs to analyse data then requires user intervention (a mouse click) to start building the directional graphs, (which take 1hr+).

I wrote a shell script using xdotool to automate the user input but it won't work when the screen is locked, it clicks on the screen saver not the target window.

I thought XSendEvent might work but it seems to be a C++ function and I don't know that language.

Does anyone know of another way round my problem?

Many thanks

	XFlush(display);
	
	XCloseDisplay(display);
}
int main(int argc,char * argv[]) {
int i=0;
    int x , y;
x=atoi(argv[1]);
y=atoi(argv[2]);
    Display *display = XOpenDisplay(0);
Window root = DefaultRootWindow(display);

    XWarpPointer(display, None, root, 0, 0, 0, 0, x, y);


mouseClick(Button1);
XFlush(display);

    XCloseDisplay(display);
    return 0;
}

build this program.suppose the out file is called a.out
then the java code can be written as :

Process proc = rt.exec("./a.out "+x+" "+y);
int exitVal = proc.waitFor();
System.out.println("Process exitvalue: " + exitVal);
