Tutorial:
Let’s make, deploy, and test the AdviceBean
We’ll write the code, compile it, start the server, start the deploytool, use the deploytool to make the DD and the ejb-jar, deploy the bean, create a client, and test the bean using the client. The only thing we won’t do is install and configure the server. We assume you already did that.
If you don’t yet have the J2EE 1.3 RI up and running, go to http://java.sun.com/j2ee/ and download version 1.3 of J2EE (it includes set-up instructions), then go back and download the J2EE API documentation.
Note
Remember, the exam is for J2EE 1.3, NOT 1.4! Whatever you do, do NOT study for the exam using the 1.4 spec. See the intro for more details about why the exam uses 1.3 and not 1.4—the short version is: we don’t want to certify folks on something that almost nobody is using. Certification is NOT about “I know the latest and greatest release”. It’s about “I know the technology that people are using now. I’ve been using it for at least six months.”
Which server would we use? We use the RI for learning and practicing because we don’t know which server you’ll need to use, and the RI is the simplest of all the freely-available servers. We want it to be as easy as possible for you to focus on EJB technology and ignore the tool-specific tasks.
Open source products like JBoss are still real production servers, so they tend to have a lot more configuration ...
