How to explain struts work flow
Answer Posted / aleem
when client makes the request,the request goes to web.xml
files <url-pattern> tag from here it goes to <servlet> tags
<servlet-class> there ActionServlet is loaded into the jvm,
and it is instantiated,initialized with in its init method,
Now the responsibility of actionServlet is to identify the
request processor,by using <inti-param> tag,after request
processor identified ,ActionServlet creates the instance of
the request processor,on that instance of request processor
calls the process(), as a result request reaches to the
requestprocessor.
the next responsibility of requestprocessor is to identify
the Action,using the client requestd uri.if client requested
uri and struts-config's path attributes are same then it
checks for the name attribute,if name attribute is found the
it goes to the <form-bean>tag there it check,if found ,sees
whether the form bean instance is available in the request
scope or not ,if found it instance set the request parameter
values by calling setxxx methods.then request reaches to the
Action. action returns the ActionForward object, using which
<forward> tag forwards to the appropriate jsp.
