1.when actionservelet execute.
2.when web.xml executes
 Question Submitted By :: Struts
I also faced this Question!!     Answer Posted By  
# 1
1)The "web.xml" comes into the the picture when the
respective server is started. When the time of server is
starting the container will check the syntax and parse
the "web.xml" file.
2)The "web.xml" file is called as a deployment descripta
because it tells the server just what the application
contains that's it beyond of that it's doesn't do any thing.

1)ActionServlet is a predefined Servlet class which comes
along with struts framework.
2)When we implemented a struts based web application then
every request and response must go through the controller
3)We can define our own ActionServlet class insted of using
the predefined ActionServlt class but in most of all cases
we will use only the predefined ActionServlet class.
4)We should configure the ActionServlet class in
the "web.xml" file like as followed




5)If we specified "<load-on-startup>" then
the "ActionServlet" class will load,instantiated and
initilized when the server or application started.
6)If we didn't specify "<load-on-startup>" then
the "ActionServlet" class will load,instantiated and
initialized when the first request comes.
