Hi Kristian,
here I send you some short pieces of my code to make the arquitecture of my
application clearer :)
This is the class to initilize the window
public class ListItems {
List listOptions;
private static ListItems instance;
private Frame f;
public static ListItems getInstance () {
if(instance == null) {
instance = new ListItems ();
}
return instance;
}
public void initWindow(int i) {
if (i== 0){
f = new Frame();
listOptions = new List();
f.add(listOptions);
listOptions.addItem("reqConn");
f.pack();
f.setVisible(true);}
if (i!=0){
listOptions.addItem("reqConn2");
f.add(listOptions);
}
}
This is the web services class:
*public* *class* SDMInterfaceImpl *extends* Thread *implements*SDMInterface{
public ListItems list = ListItems ();
*public* SDMInterfaceImpl() { }
** *public* *void* init(){
*
*list.getInstance();
}
*public* String reqConn(String src, String dst){
String result = "";
list.initWindow(0);
*return* result;
}
*public* String reqConn2(String src, String dst){
String result = "";
list.initWindow(1);
*return* result;
}
The client will call the methods reqConn and reqConn2 and on the window
should appear these 2 messages:
reqConn
reqConn2
Is it clearer now? Do not look at the class, it is a simplification to show
you how my application tries to work
regards,
Alicia

honestly, the architecture of your overall application by now seems
somewhat obscure to me. What exactly do you intend to do? Is the
"window" supposed to display the web service calls actually supposed to
be a _desktop application_ window or rather an HTML page rendered by
some JSP?
If you want to build a GUI, probably you will have to build something
like that:
* Web Service and related classes deployed to a tomcat application
context making use of axis and friends, and
* GUI application, built as a standalone Java application making use of
Swing(?) to render a GUI and using web service client classes to do
remote calls.
Can you be more verbose about your application architecture? :)
Cheers,
Kristian
