I need to get information about the time taken by tomcat server to get restarted

and also when i paste some war file inside Webapps folder i dont observe anything on the startup.bbat file............I mean it should register with that file

I think there must be some property file with variable INFO that i need to make True so to get information about starting tomcat server

Can anyone tell me where i am missing

1) anywhere from a few seconds to a few minutes depending on what you have running in it, what hardware it's running on, and what the weather is in Timbuktu.

2) depends on the configuration, hot deployment is supported but needs to be turned on in the server config. Check the Tomcat documentation on how to do that.
