I deployed a strut1.2 based application in Tomcat server. Whenever a request come into server then major part are like below
1) Invoke servlet service method 2) Then action servlet will be called 3) Then action class will be called 4) Whatever the java business class(not singleton) written in action's execute method will be called.
main feature of Servlet is multithreading
If many user access the same java business class at same time. Then server multithreading servlet means action servlet also multithreaded ,then action class also multithreaded ,then action class multithreaded ,then java business class also multithreaded?
please tell my understanding is correct or direct in right way
Action classes can be accessed by multiple threads at the same time. Have a look at the Action Class Design Guidelines. This does not necessarily mean that business logic classes would need to be accessed by multiple threads. For example, an action class could create unique instances of business logic classes to handle each request.
