Hi All,
This is regarding the calling of the destroy method. I am a bit confused
I do not think that browser has anything to do with calling of destroy method.
I think it is the servers responsibility of taking a servlet off depending on
certain criteria. I am not sure who specifies these.
When a servlet sends a reply back to the browser the connection between the two
no longer exists.
As far as reloading of a servlet is concerned the server employs custom class
loaders when the class file undergoes any change.
Please correct me if I am wrong.
Regards
Nitin
