Depending on what you mean by "Java file starts", there's 3 things you can do.

- Once on creation of a session, implement HttpSessionListener and
specify the listener in web.xml
- Once for every request, create a filter by extending
AbstractHttpFilter or implementing HttpFilter and specify the filter
and what URLs map to the filter in web.xml
- Once on startup (or shutdown) of the web app (including deployment),
create a ContextListener by implementing ServletContextListener and
specify the listener in web.xml
