Hi,
Whilst there are numerous J2EE hosting organisations out there such as EJIP which funnily enough power this forum!
Alternatively by downloading the JDK Enterprise Edition 1.3 you already have a J2EE server included, check out the famous pet store demo.
Alternatively you could download a copy of the opensource JBoss server which is used by many organisations!

Hi,
Of course i intend to advertise my book. It takes many many hours of hard work not to try and advertise it.
I did mention that there were several good books on the market and also the excellent SCWCD links which are free. There have been many posts that mention all the other books so i did not feel the need to point them out.....

Hi,
Each time a CGI request is received the web server has to spawn a new process (v.expensive) to handle it.
With Servlet technology, the reusable servlet class is usually already loaded and in memory and ready to server the request.
Dont forget CGI is implemented via a simple script file so theres not much to reuse!

Thanks Carl and congrats to all the winners!
Hope you enjoy reading our book!

Hi everyone,
Yes our objective when we set out to write the book was to provide a complete study guide that covered every objective.
I would still advise regularly referring to both the Servlet & JSP specs though to really cement your knowledge.
Cheers

Hi,
I have just tried to download the PDF and i too get an error but the PDF still opens ok when selecting 'OK'
Not sure what the problem is here it was working fine earlier.... You can always right click and do "Save Target As", download it then it works fine...
strange?!?!

Hi Ian,
Alas the book does not come with a soft copy im afraid, as i imagine it would be too tempting for someone to place a copy somewhere on the internet!
As for typos and correctness etc, the wook was techniccally reviewed buy readers from this very forum so hopefully any major problems have eradicated. Hopefully any small typos/errors if any will be very minimal and not interrupt your study.
Cheers

Hi Guennadii
This forum is exclusively dedicated to those studying for the Sun Certifed Web Component Developer exam. All questions/posts should ideally be based around peoples problems/experirnces with studying for the exam.
Many of the topics you raise such as Web Services, Java Web Start, sockets etc are not required by the exam objectives.
Perhaps you could try looking at one of the other forums at JavaRanch, which might help you get the answers you are looking for

Hi Raj,
As with all Wrox books, our SCWCD book is crammed with fully working examples. All the examples are also packaged into an examples web application with source code for you to experiment with

Hi Rick,
You are correct, currently Filters do not form part of the exam.
We decided to add a chapter on Filters as we felt it was an important subject not to include as we wanted to make the book as useful for you as possible after you finish taking the exam.
We also are safe guarding our selves for the future, any change to the SCWCD exam (when Servlet 2.4/JSP 2.0 is out???) is likely to include Filters...
We do make it very clear what is required for the exam in the book though...
Dan
Hi Burk,
The Wrox book assumes a certain level of knowledge of Servle/JSP technology. We felt an introduction from basics would make the book to large and would alienate thode developers trying for the exam....
Whilst the book does introduce topics, you do need to understand the basics...

Hi,
If the isCommitted() method returns true then the buffer has ben filled and the response has been committed to the client(ie they have the output in their browser!)
Changing the status code would be meaningless at this stage hence the error.

Engin,
The book assumes a certain level of understanding about servlets etc so i would recommend a grounding in servlets and JSP before attempting the exam.
As for Struts, there is no mention of it in the book, although there is a chapter devoted to Design Patterns (as its an exam objective) that covers MVC
Dan
Hi Cathy,
Primarily the book is designed to cover the examination (it is a study guide after all). What we have done though to try and make the book as appealing as possible is to include some sections that are not directly examinable. For example there is a section on Filters plus a fully working case study that demonstrates best practises etc..

Hi Ming,
The JDK you use is really dependant on the Servlet Container you choose. If i assume your using Tomcat then i sugest you use a JDK 1.3 or higher......
Check you servlet container documentation
