Hi,
I had the same problem, when I used a real dummy class. Then I tried to use
a "dummy" BeanInfo class which is not empty, but which is derived from
SimpleBeanInfo:
import java.beans.*;
public class MyClassBeanInfo extends SimpleBeanInfo {
public MyClassBeanInfo() {
super();
}
}
This works with IE 4 both from an IIS and from a Personal Web Server.
Best Regards,
Thomas Langhagel.

Actually I am using an IIS Server. We have a Java web server also
so I'll try putting it there. I tried the dummy BeanInfo class
and it still crashed IE 5.0.
Thanks,
Harley
