Hi,
I have some questions about hot redeployment in glassfish.
while hot redeploying an application in glassfish server(without stop and
restart glassfish server)

1-Does the application is still available for current users?
2-what going to happen when a user logs on , while making a hot redeployment of
the application?Is the user request blocked before momentarily to be written
after the new version of the application ? what happens really? can I have a
document that explains it clearly with a diagram and explaination of this
diagram?
