Agree with Marcos. I got the book (Core JavaServer Faces 3rd edition - David Geary, Cay Horstmann) myself about a couple of weeks back. Finding it very simple and easy to follow so far.

This is exactly what I was looking for. The model is much simpler now.

When you start referencing the FacesContext and/or non-model JSF classes, there's a good chance you're not doing it right

I agree; didn't feel right doing it.

Thank you so much for the clarification

True, but I meant the showText() method..getting the facesContext instance, getexternalcontext, etc..etc..till you set it back as an attribute. I was thinking my approach was long-winded and there was a shorter way

Requirement: There are 2 text boxes and a command button on a page. Type in first textbox and click the button, typed text should appear on the second textbox.

What I used: RAD8.0 default implementation of JSF2.0

What I did:

1)
<h:inputText styleClass="inputText" id="text1"></h:inputText>
<h:inputText styleClass="inputText" id="text2" value="#{textBean.textValue}"></h:inputText>
<h:commandButton type="submit" value="Submit"
styleClass="commandButton" id="button1" action="#{managedBean.showText}"></h:commandButton>

2) textBean is a request-scoped backing bean with textValue attribute and its setters and getters
3) managedBean is the RAD-generated, request-scoped bean with all the component getters, in which I have the showText action as foll
public String showText(){ if (getText1()!=null){ String text1Val=String.valueOf(text1.getValue()); FacesContext fContext= FacesContext.getCurrentInstance(); Map<String, Object> requestMap = fContext.getExternalContext().getRequestMap(); TextBean bean=(TextBean)requestMap.get("textBean"); bean.setTextValue(text1Val); requestMap.put("textBean",bean); } return "copyText"; protected HtmlInputText getText1() { if (text1 == null) { text1 = (HtmlInputText) findComponentInRoot("text1"); } return text1; }

4) finally the navigation rule
<navigation-rule>
<navigation-case>
<from-action>#{managedBean.showText}</from-action>
<from-outcome>copyText</from-outcome>
<to-view-id>/JsfTestPage.xhtml</to-view-id>
</navigation-case>
</navigation-rule>

Question: Is there a better (simpler) way to code for the above requirement? I am still trying to get my head around the lifecycle..so forgive this question..isn't it possible to do a simple text2.value=text1.value somewhere?

I have seen at least 2 posts in here that says the passing percentage is 42, whereas it is 68% in the Sun objectives link provided for SCDJWS5. Can somebody clarify. Also in the SCDJWS links, which of the books are for the new version of the exam and which are for old? The listing begins with a book for j2ee1.4. Are there books specifically for the new version?

Not so proud of the score but that's all I could do in the time I had.

Materials used: Specs (for EJB roles), the oreilly book & Enthuware for exams. I should say Enthuware helped a lot, given I did not get the time to read the specs.

Prep Time: 28 days. (1-2 hrs weekday & 3 hrs weekends)

Whats next: JWS

I started on the 21st of may and gave my exam yesterday (18th june), which is less than a month. I passed with a 75%. I spent no more than 1-2 hours a weekday and 3 hrs weekends.

Although I am not so proud of the score and I could have done better if I had some more time, I think if you are short of time, reading oreilly and using the Enthuware simulator are the best bets. That's what I did. I read only the EJB roles part from the specs, nothing else. If you have even a couple of weeks more than what I got, I am sure you can score in the 90s.

My exam voucher is expiring June 18th and amidst my tight schedule, I have decided to appear for the exam. I would hate for that fee to go a waste. I have been out of touch with Java for a year now and I haven't even started preparing for this exam. I think, starting today, I can put in 2 hours on weekdays and upto 4 hrs on weekends for the next 4 weeks for the preparation. Will this be enough to pull me through the exam?

I know there is no easy way to pass this exam, but can BCD veterans guide me on which areas to focus on given the short amount of time I have on hand? I am using Mastering EJB & EJB OReilly for books plus the specs.

Thanks.

Well I was in a similar situation during my last job hunt. There were a lot of production support offers coming up through and my consultant kept pushing me to these jobs. But I came outright with my situation and my inability to work odd hours and carrying a pager. This I did every time at the start of the interview, when they ask me about myself(as part of what kind of job I am looking at) so they can wind up the interview sooner if they really did want me to have this ability.

No matter how desperate you are to get a job, you do not want to end up in a position you'd later repent accepting.

So, absolutely this situation is subjective.

I have 5 years of experience in Java/J2ee technologies. I live in the US and I had to quit my precious job due to personal reasons. I haven't been working since mid-2007. Don't think will be able to start until early 2009. What damage am I doing to my career? I am trying to keep up to date by learning new stuff online and studying for certification exams, but I am still worried if I will be able to get back into the market easily. Any advice?

I think you have made two conflicting statements here. The fact that the certifications help you perform better in interviews itself means that the certification is of value to you.

Your interviewer might not offer you a higher pay looking at your certification, but I think he/she does know that you know your stuff well.

I assume that you do not have an understanding of the basic Java language itself. For fun learning (or serious!) the best books are the Head First series. Head First Java, Head First Servlets & JSP are the two books that you can get hold of and read through like a novel, and at the same time learn tons of stuff.

I think the answer should be "yes and no"

Java supports multiple inheritance in interfaces but not in implementations.
If asked why no multiple inheritance of implementations, then the answer is simply "simplicity". Java follows the age of C++, but is a stickler for OOP principles. Creators of Java wanted to get rid of the complexity of multiple inheritance (of implementations) that is inherent in C++.

Hope it helps

Hi,

- What do you think are the qualities that interviewers look for in a Senior Java Developer (other than expertise in Java itself)?

- Do you think certifications impress interviewers in general? What could be the rationale behind interviewers grilling developers extensively inspite of certifications and experience?

- I once flunked an interview because I couldn't answer a question on memory management, weak references etc.. What kind of developing jobs really require such knowledge?

- Does your book include practical questions..like..what would you do in a given scenario?

- Do you have any IDE-specific questions..say advantages of one IDE over another?

Thank you.

I think if I were you, I would try to somehow squeeze whatever I can get in in the 11 weeks time and take the old exam, since you are saying that you will be using the technology for at least the next few years. I am sure you can pass the exam and get some concepts in, assuming you spend at least 3 hours/day for the next 11 weeks. I would use just HFEJB plus specs.

Of course, if money is not a constraint, I would also take the new exam at a later date just for kicks.
