Leena, I have to interview couple of people in next week. I don't want to be a terminator but just looking for some latest questions!! ((:- Thanks for your help guys...
hie Engin I'm very much sure about the use of JSP: JSP is used (rather essential) in multi-tier environment...it clearly seperates the Presentation from business logic , designers can easily modify prsentation layer, and developers need not to worry about presentation... what I understand is that , JSP will become servlet in the end. so 1) there is some extra (compilation) time , first time or whenever page is modified 2) Container may add some code, that could otherwise be avoided so we use Servlets where its not related to presentation , and the part is handled by java development team only not by the designers, like the controllers in MVC architecture. please guide me if there is something else? thanx

What is model 1 vs model 2. Which do you like better Struts or JSTL? Which do you like better and why: Tomcat or Jetty?

Gosh ! Rufus, I donno anything about model1 or model2. What are they ? And jetty and JSTL also ! If you know, pls share it. JagDeep, if you are to take interviews, take it on what is important to your projects, if any. Do not end up discarding a person who might have a capacity to grasp things during the course of the project, but know a lil less at this time. Did I make sense here ? Thanks and Regards, Kirti
Model 1 and Model 2 simply refer to the absence or presence (respectively) of a controller servlet that dispatches requests from the client tier and selects views.
Model 2 is better because you can put all your entitlements/security code in one place. In my opinion MVC != Model 1 since MVC is a term for a pattern. People sometimes call Model 2 'MVC2' it's not right or wrong to do that (IMO) but it does make things quite confusing. As for interview tips: Don't get onto subjects that your not 100% confident with! Simon

Isn't there such a thing as MVC and MVC2? I thought the difference between the two was that in MVC2 the model did not notify the presentation layer after state changes? [ November 07, 2002: Message edited by: Steve Chernyak ]

Oops, accidently hit submit. Which scopes are considered thread-safe? What happens when you implement the SingleThreadModel interface on a servlet? Can a ServletContext be shared between multiple JVMs? What's the difference between the javax.servlet.SevletContext.getRequestDispatcher and the javax.servlet.ServletRequest.getRequestDispatcher methods?

Is that supposed to be a trick question? I understood Struts and JSTL to address entirely different needs (Struts is an MVC architecture and JSTL is a collection of useful tags for speeding up development?).. is that wrong? Why would someone like one better than the other - what parts of their usefulness dovetail? Thanks, g.
