I guess you could do this by creating your own event service using
the sockets package. It would be much easier if you have one of the
CORBA ORBs for Java. I think the Sun and Iona ORBs planned for Java
only implement the client side mapping. I think you would need the
server side for recieving the events.
You are in luck though. Post Modern Computing has a complete ORB
(client and server sides) called Black Widow implemented as a Java
package. I think they are ahead of the other ORB vendors with Java
support too. If you have an applet that uses it then the ORB down
loads to the browser. They are going to Beta this week or early
next week. Their info is:

The Fresco toolkit (specified using CORBA IDL) has an event service
that I find to be more attractive than the OMG standard, for simple
things. I have duplicated this for my own internal work where I
need simple event notification.
BTW, it seems to me that Java and CORBA compliment each other very
well. Java gives us the mobile code that is very important. The
standard net libraries for Java are still at a fairly low level. A
Java based ORB (like Black Widow) provides high level programming
that is location transparent for distributed computing.
I can tell you the people I talk to at the OMG meetings are all
excited about the marriage of CORBA and Java. I would expect to see
a lot more Java ORBs within the next six to nine months. Black
Widow has a big jump on them though.
