Thanks Fernando for answering my questions
I have been hearing lot of things about MEAN stack nowadays.

To know more about this I have been doing a course on MongoDB from MongoDB university. As I was doing that I noticed that there are plenty of material available online for node.js and angularJS as well. So, I have 2 questions.

1. Why should we get your book where there is plenty of free online material available?
2. How usable do you think MEAN is when it comes to enterprise applications?

I hope to win a copy this time as I believe MEAN has a huge future ahead.
I have a general question regarding Web Component EE 6 exam (I guess the rules would be similar regardless of the exam though)

Let's say if I have a question that has 2 correct choices. If I get one of them correct and another one wrong, would I get partial credit for that question (since one of my picked answer is correct) or nothing?
I am preparing for EE 6 Web Component Exam. I done Head First book very thoroughly. However, I still need to prepare for EE 6 version.

Please let me know how much effort does it require for me to upgrade myself from EE 5 to EE 6 version.
Go for latest version. There is no point doing EE 5 exam when EE 6 exam exists. If you are new to servlet world I recommend studying Head First Servlet and JSP 2nd Edition.
I am preparing for EE 6 Web component exam. One of the objective outlined on Oracle exam is "Describe and use more advanced elements of the servlet APIs"

Could someone please let me know what are the advanced elements of servlet APIs?


Also please shed some light on these objectives as well

Understand the many elements that make up the model


And good study material for these

Understand the interactions that are essential to asynchronous web pages
Understand the role of AJAX-style client side programming
Implement asynchronous servlets using the facilities of Java EE 6
Seems like you need RequestDispatcher

You use this to call one web app component from another

Example - Forwarding requesting from Servlet to JSP

RequestDispatcher requestDispatcher = request.getRequestDispatcher("\login.jsp");
requestDispatcher.forward(request, response);

Inside the jsp you can use session.getAttribute("attributeName") or even better if you use <jsp:useBean> to access that as it is better to avoid scriptlets in jsp.

Hope it helps.

I found this link and thought I should share with everyone - http://exam.piotrnowicki.com/

Hi Kishori,

I am working as a java developer and always found Java language syntax simple and easy to learn. However, as Java is progressing I am feeling that it is inclining towards functional programming and due to that it is changing its syntax rather than adding new APIs or library. What is your take on this?

Out of 3 books you had, I am mostly looking forward to APIs, Extensions and Libraries as this might change my mind.

Another question I have is - Originally some of features that were part of Java 7 could not make it and then they got put in Java 8. Has something like this happened with Java 8 as well. If yes, in brief what were those features?

Then a very open question - How do you see the future of Java language in general?

I hope to win a copy of APIs book :-)

Thanks,

Hi Kathy and Bert,

First of all many thanks for writing head first Servlet and JSP book. It is written very nicely and I really appreciate the effort you have put in writing that book.

I have a question regarding the new OCP Java SE 7 - Considering that SE 8 has been officially released for more than 6 months, is it really worth to do Java SE 7 certification? Also, I have seen that as Java language is progressing it is inclining towards functional programming style. What is your take on that? Is it good or bad?

I hope to win the copy of SE 7 as your books are very nice.

Thanks,
Prabhjot Singh
Hi Craig,

I started learning Spring using Spring in Action 3rd Edition and while doing that I realized it is good to have solid foundation of J2EE before diving into Spring as the purpose of Spring framework is to get rid of the shortcomings of J2EE.

I have couple of questions for you

1. According to you, which particular topic should be a part of Spring framework which Spring doesn't have at the moment?

2. Any language/framework has pros and cons. According to you, what are the disadvantages of using Spring and how we can overcome that?

Thanks,
Prabhjot

Hello,

I am planning to give certification of Java Servlet and JSP certification. The latest version available for certification is EE 6. However, Java EE 7 has been out for more than an year now.

Does anyone have an idea when would the certification exam of Servlet and JSP based on Java EE 7 be out ?
