Mihai,
This pattern has since been renamed Transfer Object or Data Transfer Object.

Stuff is actually where you want it to be and it does everything you want and then some without being intrusive to what you are there to do..code. The experience using IDEA just doesn't compare with any other IDE I have used (Eclipse, NetBeans(and Forte), or JDeveloper. I'm not going to get into the features it has, but I will say the features it does have are all just intutitive to use and poweful.


Similar experience here. I've been using IDEA for about a year now, and I can't recommend it highly enough! Great move, Rick!

Agreed. I couldn't find a way to customize keyboard and went back to IDEA.


Good move!

Do you know of any way to create keyboard shortcuts for ANT builds within IDEA?


It sounds like you might not be using one of the more recent builds of the upcoming version 3.0. These are available from the IntelliJ Technology Network's Early Access Program (free registration).
In the recent builds, defining keyboards shortcuts is done using the Options->Keymaps editor. There, keyboard shortcuts can be defined for every single Ant target contained in your current project's build file(s).
Good luck!

Ronnie,

IMHO, I would strictly adhere to the conventions defined in the Code Conventions for the Java Programming Language
as well as in the Java Coding Style Guide just to be on the safe side, as the former seem to be missing some.
According to the above, your code should look like this:


Good luck with your assignment!

Thanks a million Simon, this bit of advice was exactly what I've been looking for. Very handy!

However I reiterate that there are lots of very good people looking for work and you will be joining the queue, that queue includes plenty of people with 4 years java and domain experience. So you will be taking you place at the back of that queue. If your serious about this career path think about doing something like 'MSc Financial Markets with Information Systems'. It will do much for you than a MA in Music :/
Sorry if that sounded like a good kicking when you were looking for a hug.
Simon


I totally agree with Simon here. FYI, London Guildhall University offers a course in MSc in Financial Markets with Information Systems.. I'm yet to find out more about it myself.
Cheers,

Safrole,
There's a Yahoo! Group created by Aaron Robinson (SCEA_J2EE moderator) at the following link:

Well done Leon, and good luck with Part II !

Congratulations Franck, a great score.Could you give any advice on how to prepare for the exam.
Syed.


Well, in a nutshell, I tried to stick to the exam objectives. This is how I prepared for Part 1:
Concepts
I read UML Distilled two years ago, and UML User Guide last year.
Common Architectures
I only read chapter 1 of the EJB code camp available from Sun's web site (not JavaSoft).
Legacy Connectivity
Based on field experience.
EJB
I read the classic 'Enterprise JavaBeans, Monson-Haefel' last year, and perhaps, I wrongly assumed that experience would be enough...
EJB Container Model
I re-read chapter 2 and 8 of the aformentioned book.
Protocols
I only concentrated on the objectives, but that clearly wasn't enough...
Applicability of J2EE
Based on field experience.
Design Patterns
I studied that one thoroughly, as well as how it maps onto the EJB model, using the classic 'Design Pattern' by the Gang of Four.
Messaging
Based on an understanding of the concepts.
Internationalization
I have worked on internationalized applications in the past, but
I re-read the i18n trail of the Java Tutorial, just in case...
Security
I revised encryption, digital certificates, and applet security FAQ from JavaSoft.
The few days before taking Part 1, I took the online mock exam for IBM 483 as well as Jaworski's, and consistently got 100%. But then again, they don't target the same exam...
Cheers
Franck
Thanks guys ! Although I didn't mention John's great notes in my previous post, you can search for them among the February posts if I remember correctly...
Good luck !
F-A-N-T-A-S-T-I-C !!! See, hard work always pays off at some point... I wish I had remembered that when preparing for Part 1...
I'm glad this is over I haven't got much more to write about Part 1 that hasn't been written before, except that I certainly did get confused by the wording of some of the questions... Nevermind, here's the score report:
Concepts 100%
Common Architectures 50%
Legacy Connectivity 100%
EJB 77%
EJB Container Model 100%
Protocols 66%
Applicability of J2EE 100%
Design Patterns 100%
Messaging 100%
Internationalization 100%
Security 100%
I mainly revised all topics but Common Architectures, EJB, and Protocols... and it shows

Hi Bjarki and Franck,
Thank you for your replies.
I was (am) following EJB vs JDO discussions, but my interest is in low-end (micro, embedded) solutions, where EJB is not an option.
But as a side question - I haven't seen any EJB - JDO performance comparisons ... Would somebody risk an opinion?
Kathy


Well, this is a tough one, mainly for the following inter-related reasons:
1. The JDO spec isn't finalized yet.
2. Although many vendors have already announced or released beta
products, none of the products fully integrates with existing
J2EE application servers. This is due to the fact that
support for the J2EE Connector Architecture in both JDO
products AND J2EE application servers still needs to mature.
You may have heard of Castor JDO, which is quite similar to the
JDO standard although it doesn't implement it. Castor has been
integrated with jBoss 2.x about 6 months ago. Someone on the Castor mailing list reported that the use of Castor JDO within Session Beans was indeed slower than straight JDBC. As to how it
compares to EJB, my guess would be that it can be expected to
be slower, again because of the many levels of indirection between the EJB container and the data store... Given my interest in JDO, I would obviously love to be proven wrong on this one ;-)

I totally agree. The overhead of a JDO engine running on top of a JDBC layer as mentioned by Bjarki will translate into poorer performance, which few people may be prepared to live with, while others would rather stick with straight JDBC.
It will be interesting to watch the evolution of JDO in terms of performance, community adoption, and its hypothetical integration within the J2EE Platform... (see the JDO vs EJB debate on TheServerSide)

Frank, I think he is talking about DB2 and cics. Am I right, Prameet? Yes you can. You need the appropriate drivers. For non-standard databases for which there are no drivers written, the solution would be custom made, I think.


Well, I would be surprised if there wasn't any JDBC driver for IBM's DB2. As to connectivity with CICS, IBM (obviously) provides connectors for it. In fact, the whole concept of connectors for Enterprise Information Systems was originated by IBM, and later standardized with the J2EE Connector Architecture.
Parmeet, what type of architecture does your application follow ?
If it a J2EE application, you may want to take a closer look at WebSphere 3.5 (or greater) or WebLogic 6.x (with JCA support).
Then, you would need to write a resource adapter for your legacy data store, and declare it in the deployment descriptor for your EJBs... I'll stop here, since I may be way off track by now ;-)
Good luck

Prantik,
what JDBC drivers are you using? Most likely, if they are JDBC 2.0 compliant, they come with an implementation of the <code>javax.sql.ConnectionPoolDataSource</code> interface, which can be be used for connection pooling.
Cheers,


Not necessarily. The <code>javax.sql.ConnectionPoolDataSource</code> interface is not part of JDBC 2.0 Core. It belongs to the JDBC 2.0 Optional Package (a.k.a. Standard Extensions). Therefore, if it doesn't support the JDBC 2.x spec, you can either write your own connection pooling framework or use an existing one such as PoolMan, which is free and open source.
