A New Year gift to all aspiring SCBCDs.
Thanks Cameron. I am going today to buy it.
Thanks Paul.

I fall in the category of people who don't like to write xml files. so, may be annotations suit me better.

I happened to see a tutorial on Hibernate using JPA at http://www.thebookonhibernate.com/HiberBookWeb/index.jsp by the author of Hibernate Made Easy and found it amazing.

Did any one read the book Hibernate Made easy? Is it as good as the tutorial given?

Thanks,

What is the better approach for using the Hibernate in a new project? Use XML mapping files or JPA annotations?

Thanks,

Thanks Tim,

Thanks a lot. I think I got some answers and I will do some research before we zero-in on some thing.

Wonderful experience talking to you all.

Thanks Paul, Tim, and Wouter,

I would also get (a lot of) people involved that know what they're talking about, who have done this before.



That is what I am trying to do.

More specific I can't be. It depends on a number of factors, and it's not exactly something I can do for free.





Just one question more,

Can I start the project using traditional Java Technologies such as a web framework, EJB/JPA combination, and Lucene for some of the searches in the documents. Will they be able to scale as I add more hardware?

Really appreciate the help.

Thanks,

Thanks Tim,

By clustered servers, do you mean clustered application servers or clustered database servers or both? Can you explain what do you mean by redundant resources? and can you give me names of "very powerful database servers"?

Also, the number of users that I have mentioned will not be using the site from day one. It's only that the web site should scale to those many users as time goes on.

Can you please give me suggestions with the technology selection?

Thanks,

Hi all,

we are expecting a project which has high number of concurrent requests. The application will have 5 million registered users and approximate number of users online at a time is around 100,000. The business logic is not complex. But handling the traffic is our problem. Can any one let me know the strategies in implementing such a web site.

Thanks,

Hi all,

I was able to solve it. JSF 2.0 requires beans.xml in WEB-INF if you use CDI even though it may be empty.

Hi all,

when I run the following code, I get an error "Target Unreachable, identifier user resolved to null". Can you please tell me where I am going wrong?

Hi Akaine,

Thanks for the information. One more clarification required. If I use Rich Faces with JSF 1.2 and want to transition to Icefaces using JSF 2.0, will it be an easy one?

Can you recommend any good books/tutorials?

Thanks,

Hi all,

I am newbie to JSF and want to learn . Where and how should I start? I heard names like myfaces, icefaces etc etc. What are the differences between them? Do they have different APIs and tag libraries or same API and different implementations? It is better to learn which version JSF1.2 or JSF2.0? I am also considering taking JSF certification once it goes live. How can I make my learning JSF to help me take certification also?

Thanks in advance,

Hi Rob

Caching of Long values is not guaranteed.


Why do separate autoboxing conversions sometimes return the same reference?

Two autoboxing conversions of a primitive value p will yield an identical reference (that is, the == comparison will return true) if p is:

* true or false
* a byte
* a short or int in the range of a byte (-128 to 127)
* a char in the range of \u0000 to \u007f (0 to 127)

Note: The Java Language Specification does not explicitly guarantee this behavior for long values within the range of a byte.

Thanks Rob,

I got to know something new

Java pools auto boxed values Boolean, Byte, Character(from \u000 to \u007f), Short and Integer from -128 to 127.
