Thanks for the article, it was very good, my problem is more specifically
the implementation of a pattern like that with Axis. I am trying to prove
its workability with a simple stateful session bean:
public class CounterEJB implements SessionBean {
private int count = 0 ;
public void reset() {
count = 0 ;
}
public int add(int i) {
count += i ;
return count ;
}
/*
* ----- cut Session Bean Required Methods cut -----
*/
}
The bean home defines a single create() method and its remote interface
declares reset() and add(int i).
I have deployed this EJB as a web service using the Axis EJB provider and
modified the WSDL2Java output to maintain the session. This all functions
correctly, the SWING client can submit a value, it is added to 'count' and
the cumulative result is returned.
What I would like to have is the CounterEBJ trigger an event when 'count'
changes that the SWING interface can observe and then update its display,
only problem is I'm a bit stumped as to how this should work :-(
Any pointers would be really helpful
Evan
