INTERVIEW QUESTIONS J2EE SERVLET DETAILS

Question: What is the request processor in struts? how it works?

Answer: The RequestProcessor Class is the actual place where the request processing takes place in a Struts controller environment.When the request object first reaches the actionservlet class then it invokes the process method of the underlying RequestProcessor Class.This process method then looks into the struts-config.xml file and tries to locate the name of the action that has come with the request.Once it identifies the action in the xml file it continues the rest of the steps needed for request processing(for details on this pls go thru Wrox).
