Title: RE: [jdjlist] Chat rooms

Looks like there can bee help to get here. And I really need some.. I'm supposed to develop a three-tier web-aplication before april and don't know where/how to start!!!  A bit embarassed to ask questions I know I could find the answer too in books and with enough practice, I don't have the time and hope someone will be kind enough to help me get started.   We have chosen Oracle database (8i) and j2EE. So far we''ve been modelling and planning, and have made a test database. Because the technology is new to us, the modelling (UML) has stolen a lot of time and effort, but not really given a base to start building the system. We're just studying Servlets and EJB but haven't really understood how to use this well and what to use when.  The modelling we're doing is based on j2SE-experience and lots of "traditional" jaca-classes and we dont know how to get to the next level.   So far we'vw used Forte, but was not very pleased and have chosen to try JDeveloper with BC4J framework and hope to get some things free there. Aware that we complicating things using an unknown enviroment, we hope to get better quality (security, scalability etc) of the application.   I have studied the book store example of the DeitelDeitel book and a bit on the Pet Shop (but it's huge..) and read about DAO and MVC I've also bought the JDeveloper Handbook. But I need more input to understand which and what type og components I should build. Can anyone give me some advice or a link to al place where I can find a class-diagram that shows the structure of a application like this or a comprehensive example (not as complex as the Pet Shop)   Thank you!   ----- Original Message ----- From: Greg Nudelman To: jdjlist Sent: Wednesday, March 05, 2003 8:59 PM Subject: [jdjlist] RE: Chat rooms Dear William, 1) Go for it!  Sounds like fun.  When this economy with the stupid world war games rolls me under (which is never, I hope) you may find me looking for a job and enhancing my www.HotSciFi.com website with the J2EE discussion group myself.  You might want to check out "Joel on Software" for an easy to build, yet very finely designed discussion group/chat room. 2) I would start with JSP/Servlet controller model and use a free easy-to-use JSP engine like tomcat.  I would use the full MVC architecture (see Sun Pet Shop or any J2EE book) but leave the concrete names of app-objects out of my code and use the decorator (session controller bean) pattern and DAO architecture for DB, to call simple Java objects right in the servlet layer.  This is easy to build (and "correct") and then you can scale to something like JBoss where you can deploy real entity/session enterprise beans with little code change to your JSP/servlet classes. > I want to get certified in JAVA2EE. Good for you, but I can't help you here. In my expereince, you'll gain much knowledge from building and deploying the system model you mentioned.  Good luck!

Is this possible? 2.) What classes would I need? The next question is: I want to get certified in JAVA2EE. 1.) Is there a certification? 2.) Are there any good books on testing? Please all help me with these questions!!! -----Original Message----- From: TommCatt [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 04, 2003 1:14 PM To: JDJList Subject: [jdjlist] Re: gap between universities and employers ???? From: "Jason Bell" <[EMAIL PROTECTED]> > May I just say as someone with no university education.... never did me any > harm.... I worked for years without a degree and there would be times when it actually worked to my advantage.  Large companies usually have a minimum pay scale determined by experience and degrees.  They could offer me less than the other job applicants with degrees and the same experience.  I would, in effect, go to the head of the line. However, generally I have found it better to have the degree. > A CTO and writing for JDJ.  Not boasting, but just proving that anything is > possible. Hey, I get JDJ.  I guess I'll have to start paying attention to the author's name when I read an article. 8^) No offense intended, but I have found that, many times (but there are exceptions), people who are best at writing about programming are not the same ones who are best at programming -- and vice versa.  Here's hoping you're one of the exceptions. In that same vein, many times top notch programmers (developers, Software Engineers, whatever) can't write a resume to save their life.  Top technical talent tend to be shy and self-effacing.  They don't like to brag or bring undue attention to themselves or their accomplishments.  So when I come across a resume that fairly glows in my hands, my first impulse is to throw it away.
