JBoss to Apply for Official J2EE Certification
Jonboy X writes "CNet has an article detailing the resolution of a long-standing feud between open-source J2EE server vendor JBoss and Sun. It seems they've decided to break down and shell out the clams to be certified by Sun. Quoth Bob Bickel, JBoss's vice president of corporate development and strategy: 'Our core base of developers, a lot of them say they don't give a damn...But the reality is that a lot of big companies who are using this are moving into production.' JBoss gives away its server software and survives on support contracts."
It's simple Jboss is an open source implementation of the J2EE Specification.
Done, without using "business logic".
Of course, you're no further along than when I started.
So What's J2EE you ask, Well That's where it gets more complex. J2EE is a large thing, but it basically runs down to this.
1. Have Client code that knows how to display the data (Either a webpage or a client application, etc)
2. Have a middle tier system that provides the ability to do things (basically it's a bunch of methods and objects that a client can use, no matter the client) This is where the work is done, like calculations, rules like "You have to have a PO on file in recieving before you can have something shipped here", and other things. That way you can change the rules and calculations without having to update the client, and so all clients use the same rules and calculations. - JBoss does this job.
3. A backend Data Store, (Normally an RDBMS) this stores data for the Middle Tier to use.
Basically it provides for sepirating Presentation, Logic, and Data (come on, I said logic, not "business logic", it's close enough right?)
4. Profit - wait how'd that get in there?
